Introduction
7Rings Gaming develops video slots and arcade-style casino games built around interacting symbols, multipliers and bonus features. The supplied General Game Catalog contains 29 titles: 27 classified as Slots and two arcade formats. This is the scope of the supplied file, not a claim that all 29 are available at every casino or that the catalogue will never change.
The games span fixed paylines, ways, clusters, All Pay, instant payouts and accumulated winnings. This review compares every title in that catalogue, then examines the cost of ordinary play, feature purchases and boosters. The detailed Necro Party section elsewhere on this page provides the illustrated individual-game review and free-play demo.
Company and Distribution
7Rings Gaming launched in 2025. Hub88 announced a distribution partnership on March 9, 2026, when the portfolio was described as containing 17 titles. The supplied catalogue used here is a different, larger snapshot. Distribution gives casino operators access to the games; it does not make 7Rings the operator of those casinos.
The assessment below concerns the software and its published mathematics. A host casino’s banking, service, promotional terms and player protections are separate considerations.
Reading the Catalogue
Game specifications below come from the supplier’s spreadsheet, not an independent reconstruction of its mathematics. Ordinary-play RTP comes from its RTP % field. Its maximum column is headed MAX WIN (SIM), x; those listed multipliers are reproduced as catalogue figures, not independently verified contractual payout caps. Formats retain the ordering supplied in the file.
The spreadsheet has both VARIANCE and VOLATILITY RATING fields. Where they disagree, both labels are shown, with the volatility-rating entry first. Different labels in those two fields do not prove that two configurations exist. The file also contains a few conflicting payout-count entries, which are identified rather than silently corrected.
Game Catalogue and Specifications
Each title in this comparison has a matching profile below. The ordinary-play RTPs in this file range from 96.00% to 96.66%. Purchase, booster and ante returns are considered separately in the mathematical section.

Line Games: Wilds, Multipliers and Bonus Features
Catalogue reference graphic; not a gameplay screenshot, paytable or payline map.
Necro Party
Catalogue RTP: 96.39%. Volatility: Medium. MAX WIN (SIM): 10,000×.
Moving wilds, a progressive multiplier and the Pentagram are the catalogue’s defining features for Necro Party. Its 100× and 250× purchases, 50× Game Booster and 3× ante each have their own disclosed return; the comparison below shows why a single RTP does not describe every option. The detailed Necro Party section on this page contains the illustrated game review and free-play demo. The supplier catalogue gives ordinary-play RTP as 96.39%, superseding the earlier 96.40% figure used in this overview.
Dead Gun
Catalogue RTP: 96.09%. Volatility: High / Medium (fields differ). MAX WIN (SIM): 20,000×.
The catalogue identifies progressive multipliers and both wild and multiplier spawners. It lists 100×, 250× and 500× purchases plus a 50× Game Booster. The separate volatility fields disagree: VOLATILITY RATING is High, while VARIANCE is Medium. That is a documentation conflict, not proof of two selectable versions.
Wild Bite
Catalogue RTP: 96.05%. Volatility: Medium High. MAX WIN (SIM): 10,000×.
Wild Bite brings together sticky wilds, sticky free-spin symbols, sticky multipliers and a total multiplier. The important distinction is between an element retained under the feature rules and a result that merely appeared on an earlier spin. Its catalogue purchase options cost 100×, 250× and 500×; their returns are not all identical to ordinary play.
Book of Wild West
Catalogue RTP: 96.15%. Volatility: Medium High. MAX WIN (SIM): 10,000×.
The feature list names the Book and additional reels, with purchases at 100× and 250×. The payout-mechanic field says Lines, but the count field says No. The review therefore identifies it as line-paying without importing a line count from another source. Its base format is reproduced as 3 × 5, exactly in the catalogue’s ordering.
Mayan Apocalypto
Catalogue RTP: 96.38%. Volatility: High. MAX WIN (SIM): 15,000×.
Mayan Apocalypto combines moving wilds with wheels awarding random multipliers and free spins. Its listed MAX WIN (SIM) value is 15,000×. The catalogue’s maximum-exposure entry does not equal that multiplier times its listed €100 maximum bet, so this review does not convert the multiplier into a supposedly guaranteed cash ceiling.
Magic Boost
Catalogue RTP: 96.10%. Volatility: Low. MAX WIN (SIM): 2,500×.
Magic Boost is consistently labeled Low in both volatility-related fields. Wild spawners, multiplier spawners, symbol upgrades and a Pot mechanic give it a different feature mix from the higher-volatility line games. The catalogue specifies a 5 × 5 base format, 20 lines and purchase prices of 50×, 75× and 150×.
Heart of Gems
Catalogue RTP: 96.04%. Volatility: Medium. MAX WIN (SIM): 2,500×.
Heart of Gems uses a 5 × 4 field, 20 lines and features described as guaranteed wins and instant wins. Those labels do not mean guaranteed net profit. Its 80× purchase is listed at 96.99% RTP, compared with 96.04% for ordinary play; the difference is meaningful only after accounting for the much larger transaction price.
Zombzilla
Catalogue RTP: 96.31%. Volatility: Medium. MAX WIN (SIM): 10,000×.
Zombzilla is the catalogue’s explicitly bidirectional line game, with 40 lines, reel rotation and a progressive multiplier. It has 100× and 200× purchase entries and a separate bonus-gamble entry. The source does not provide enough gamble probabilities to turn that entry into a recommended strategy.
More Line-Paying Designs
Catalogue reference graphic; not a gameplay screenshot, paytable or payline map.
Cannon Storm
Catalogue RTP: 96.45%. Volatility: Low / High (fields differ). MAX WIN (SIM): 5,000×.
The Cannon is listed as a wild spawner on a 5 × 3 field with 20 lines. Cannon Storm’s ordinary-play RTP is 96.45%, but its volatility fields disagree: Low in VOLATILITY RATING and High in VARIANCE. Its clearly priced 100× purchase is listed at 96.92% RTP; that return must not be assigned to every Cannon Storm wager.
Criminal Circles
Catalogue RTP: 96.29%. Volatility: Medium / High (fields differ). MAX WIN (SIM): 2,500×.
Criminal Circles uses a mafia theme, field extension, an Arrest symbol and a feature described as guaranteed wins. It lists a 100× purchase. The guaranteed-win description does not establish an award greater than the amount paid, and the Medium volatility rating conflicts with the separate High variance entry.
Trojan Duels
Catalogue RTP: 96.24%. Volatility: High. MAX WIN (SIM): 10,000×.
Trojan Duels combines multipliers, a spawner, a Bow and a Duel feature. Its maximum-base-format entry explicitly includes additional reels, rather than describing the initial 5 × 3 screen as the whole feature. Its 2.6× ante and 10× Game Booster also appear among the broad purchase-cost entries, so those low-price modes should not automatically be called guaranteed bonus entries.
Triumph
Catalogue RTP: 96.20%. Volatility: Medium / High (fields differ). MAX WIN (SIM): 5,000×.
Triumph pairs a Roman theme with a Duel and symbol replacement, on a base format described as 5 × 3 with additional reels. Its catalogue volatility labels are Medium and High in different fields. As with Trojan Duels, the low-price entries overlap ante and booster modes; price alone does not establish what is guaranteed.
Jusik Shots
Catalogue RTP: 96.03%. Volatility: High. MAX WIN (SIM): 10,000×.
Jusik Shots lists a music-bar theme, bonus multiplier level-ups and Coins carrying multipliers. Its purchase-RTP field contains two different returns attached to a 250× price. Those entries cannot be matched to distinct named options from this file alone, so they are not collapsed into a single purchase return.
Blood Hoppers
Catalogue RTP: 96.34%. Volatility: High. MAX WIN (SIM): 25,000×.
Blood Hoppers uses Fleas that act as wilds with multipliers, plus a Magnifying Glass feature. Its 25,000× MAX WIN (SIM) entry is the largest in the supplied catalogue, not a statement about every game the studio may offer. The listed purchase prices are 50×, 100× and 250×.
Wild Monkey
Catalogue RTP: 96.23%. Volatility: High. MAX WIN (SIM): 10,000×.
Wild Monkey’s feature list includes Lucky Coins, bonus choices, a Max Win symbol and Double Win. A visible maximum-award symbol does not reveal its probability. The supplied hit-frequency cell is stored differently from the other percentage cells; it is omitted here rather than interpreted as an unqualified percentage.
Egypt Apocalypto
Catalogue RTP: 96.00%. Volatility: Medium. MAX WIN (SIM): 20,000×.
The supplied record gives a 4 × 5 format, 20 lines, Medium volatility and a 20,000× MAX WIN (SIM) entry. Its feature list includes wheels awarding random multipliers and free spins, plus guaranteed wilds. The catalogue does not substantiate the four-profile Low-to-Extreme table previously used in this review, so that table is not repeated.
Ways Games and All Pay
Catalogue reference graphic; not a gameplay screenshot, paytable or payline map.
Crazy Shark
Catalogue RTP: 96.01%. Volatility: High. MAX WIN (SIM): 10,000×.
Crazy Shark has 3,125 ways on a 5 × 5 field. Its feature list includes a Shark Fin wild spawner, Coin Fish instant wins and a special maximum-win bonus. The catalogue gives ordinary-play RTP as 96.01%, with different returns for the 2.5× ante, 6× booster and larger purchases; these are separate paid modes.
Godshot
Catalogue RTP: 96.38%. Volatility: High. MAX WIN (SIM): 10,000×.
Godshot uses 243 ways on a 5 × 3 field, with multipliers, a spawner, Chains and additional reels in its feature list. Its ordinary-play RTP is 96.38%, while the 100× purchase is listed at 96.33%. A shared title does not make those returns interchangeable.
Train to Hell
Catalogue RTP: 96.13%. Volatility: High. MAX WIN (SIM): 10,000×.
Train to Hell lists a 7 × 5 format and 78,125 ways, alongside a progressive multiplier and a dynamic drum size. The identity 57 = 78,125 is arithmetically consistent with five positions in each of seven columns. It does not, by itself, specify which combinations pay or the probability of any result.
Alien X-vasion
Catalogue RTP: 96.00%. Volatility: High / Medium (fields differ). MAX WIN (SIM): 20,000×.
Alien X-vasion has a 5 × 5 field, 3,125 ways, a progressive multiplier and a multiplier spawner. The catalogue gives 96.00% RTP and a 20,000× MAX WIN (SIM) value. Its volatility fields disagree between High and Medium; the file does not identify those labels as separately selectable profiles.
F* Louvre
Catalogue RTP: 96.00%. Volatility: Medium. MAX WIN (SIM): 5,000×.
F* Louvre is recorded as a 3,125-ways game with Medium volatility and a 5,000× MAX WIN (SIM) entry. Its feature list includes wild spawning, instant-win symbols, a MaxWin symbol and an increasing total multiplier during the bonus. These supplier entries replace the earlier Pay Anywhere, High and up-to-50,000× description.
Bar of Fate
Catalogue RTP: 96.44%. Volatility: High. MAX WIN (SIM): 10,000×.
Bar of Fate is the catalogue’s All Pay title. Its feature list identifies Coins, a total multiplier, a Mini Slot and a gamble feature. Ordinary play is listed at 96.44%; its 100×, 200× and 500× purchases have separate returns. The catalogue does not contain a symbol paytable or the probability of success in the gamble.
Cluster Games
Catalogue reference graphic; not a gameplay screenshot, paytable or payline map.
Lords of the North
Catalogue RTP: 96.02%. Volatility: High. MAX WIN (SIM): 10,000×.
Lords of the North lists a 7 × 7 field, a Boat wild and a Boat Level-Up feature. Its payout field says Clusters, but another field says 20 Lines. This review retains the cluster designation and flags the incompatible line-count entry rather than inventing a hybrid winning rule. A repeated 250× purchase price also remains unresolved.
Sweets or Teeth
Catalogue RTP: 96.66%. Volatility: High. MAX WIN (SIM): 10,000×.
Sweets or Teeth has the highest ordinary-play RTP in the supplied file, 96.66%, with High volatility. Coins, Tickets and a Knock Character feature are listed. Its payout field says Clusters while the count field says 20 Lines; the source therefore does not support an exact line map. The 50×, 100× and 500× purchases have distinct returns.
Flames and Greed
Catalogue RTP: 96.12%. Volatility: High. MAX WIN (SIM): 10,000×.
Flames and Greed uses a 7 × 7 cluster format and lists a progressive multiplier and progress bar. Those labels describe features, not their full interaction or collection thresholds. The file supplies two purchase prices, 100× and 500×, with RTPs of 96.00% and 96.13% respectively.
Mouse Ananza
Catalogue RTP: 96.19%. Volatility: Medium-High / High (fields differ). MAX WIN (SIM): 5,000×.
Mouse Ananza is recorded as a 5 × 6 cluster game with a progressive multiplier. The count field says 12 symbols; the file does not define that entry as a minimum cluster size, so no such threshold is assumed. Its volatility fields differ between Medium-High and High.
Arcade Formats and Coin Mechanics
Catalogue reference graphic; not a gameplay screenshot, paytable or payline map.
SnakeX Arcade
Catalogue RTP: 96.01%. Volatility: Adjustable. MAX WIN (SIM): 10,000×.
SnakeX Arcade is classified as Arcade Gambling, with an Open World format, Instant Payout, a progressive multiplier and a Jackpot feature. It has no listed paylines, ante or bonus purchase. The catalogue does not specify four starting lives, a four-world sequence or exact selectable risk settings, so those earlier infographic claims are not used here.
SnakeX-mas
Catalogue RTP: 96.01%. Volatility: Low. MAX WIN (SIM): 250×.
SnakeX-mas is a separate Arcade Crashout title, not an alternative spelling of SnakeX Arcade. It lists accumulated winnings, Santa Claus, Low volatility and a 250× MAX WIN (SIM) entry. The official identifiers also differ: islx-snake-cave versus islx-snake-world. No ante or bonus purchase is listed.
Multi Bandit
Catalogue RTP: 96.00%. Volatility: Medium. MAX WIN (SIM): 10,000×.
Multi Bandit is classified as a Slot with a 1 × 3 base format and a Coins payout description. Its line-count field is a dash, not one confirmed payline. The catalogue lists wild spawning, instant-win symbols, a MaxWin symbol and an increasing bonus multiplier, with 100× and 250× purchases.

RTP and House Edge
RTP is expected gross payout divided by the corresponding amount wagered. It is not the probability of a winning spin. For a fixed planned amount of wagering W evaluated at an applicable return r, expressed as a decimal:
House edge = 1 − r.
Expected gross payouts = W × r.
Theoretical expected loss = W × (1 − r).
| Catalogue entry | Ordinary-play RTP | House edge | Theoretical loss per $1,000 |
|---|---|---|---|
| Sweets or Teeth | 96.66% | 3.34% | $33.40 |
| Cannon Storm | 96.45% | 3.55% | $35.50 |
| Bar of Fate | 96.44% | 3.56% | $35.60 |
| Necro Party | 96.39% | 3.61% | $36.10 |
| Dead Gun | 96.09% | 3.91% | $39.10 |
| SnakeX Arcade / SnakeX-mas | 96.01% | 3.99% | $39.90 |
| Alien X-vasion / Egypt Apocalypto / F* Louvre / Multi Bandit | 96.00% | 4.00% | $40.00 |
The ordinary-play range in this catalogue corresponds to a theoretical cost of $33.40 to $40.00 per $1,000 wagered. That is a comparison of expected costs, not a forecast of individual sessions. In particular, Necro Party’s catalogue return of 96.39% gives a 3.61% house edge and $36.10 theoretical loss per $1,000. The earlier 96.40% figure would produce a different calculation.
Wagering is not the same as a deposit: returned money can be bet again. Free spins awarded without an additional charge belong to the paid round that triggered them, rather than creating a new expenditure on every bonus spin. These overall-return comparisons also need not equal the conditional return from a particular retained-wild position or unfinished feature.
Necro Party: Ordinary Play, Ante, Booster and Purchases
The catalogue separates ordinary play, ante, Game Booster and bonus-purchase returns. Let b be the reference bet used in its cost multipliers. The table uses b = $1 purely for illustration; the displayed cost must be the full amount charged. The source identifies the two purchases by price rather than by their in-game marketing names.
| Mode | Catalogue cost | RTP | House edge | Cost at b = $1 | Expected loss at b = $1 |
|---|---|---|---|---|---|
| Ordinary play | 1×b | 96.39% | 3.61% | $1.00 | $0.0361 |
| Ante bet | 3×b | 96.32% | 3.68% | $3.00 | $0.1104 |
| Game Booster | 50×b | 96.22% | 3.78% | $50.00 | $1.8900 |
| 100× purchase | 100×b | 96.43% | 3.57% | $100.00 | $3.5700 |
| 250× purchase | 250×b | 96.04% | 3.96% | $250.00 | $9.9000 |
Source: Necro Party column in the supplied catalogue, including the separate purchase, Game Booster and ante fields. Expected losses are calculated from those disclosed returns and prices; they are not independently simulated game results.
All five modes use their own catalogue RTP; the $1 reference bet is an illustrative scaling choice.
At that reference bet, the 100× purchase has an expected gross payout of $100 × 0.9643 = $96.43 and an expected loss of $3.57. The 250× purchase has an expected gross payout of $250 × 0.9604 = $240.10 and an expected loss of $9.90. A smaller house-edge percentage does not make a larger transaction a smaller dollar exposure.
The 100× purchase’s 96.43% return is 0.04 percentage points above the ordinary-play 96.39% return. It is still below 100%, and it costs 100 reference bets at once. Expected value and transaction risk must both be considered; neither figure guarantees a profitable bonus.
Feature Returns Across the Catalogue
The following examples show why each paid mode needs its own return. Prices below are multiples of the reference bet. A low-priced entry appearing in the broad BUY BONUS fields may also appear in the ante or booster fields; that overlap is not evidence that the entry guarantees a complete bonus.
| Game | Ordinary play | Ante / Game Booster | Other listed purchases |
|---|---|---|---|
| Bar of Fate | 96.44% | 3× ante: 96.25%; 50× Game Booster: 96.10% | 100×: 96.08%; 200×: 96.04%; 500×: 96.13% |
| Dead Gun | 96.09% | 3× ante: 96.13%; 50× Game Booster: 96.11% | 100×: 96.01%; 250×: 96.16%; 500×: 96.00% |
| Crazy Shark | 96.01% | 2.5× ante: 96.84%; 6× Game Booster: 96.20% | 125×: 96.28%; 250×: 96.10%; 500×: 96.56%; 2,000×: 96.00% |
| Sweets or Teeth | 96.66% | 2.4× ante: 96.33% | 50×: 96.67%; 100×: 96.63%; 500×: 96.28% |
| Heart of Gems | 96.04% | 1.3× ante: 95.96% | 80×: 96.99% |
| Cannon Storm | 96.45% | 2.5× ante: 96.17% | 100×: 96.92% |
| F* Louvre | 96.00% | 1.3× ante: 96.00% | 50×: 96.00%; 250×: 96.00% |
For example, Heart of Gems’ 80× purchase has a 3.01% house edge at the listed 96.99% return. With a $1 reference bet, its expected loss is $80 × 0.0301 = $2.408, approximately $2.41. That is higher in dollars than the $0.0396 theoretical loss on a single ordinary $1 wager at 96.04%, despite the purchase’s better percentage return.
The expected net loss on a purchase of price C at its applicable return rB is C × (1 − rB). Its actual net result is total payout minus that full price. A $100 purchase returning $60 loses $40 regardless of the accompanying win animation.
Volatility, Hit Frequency and Maximum Awards
RTP measures average return; volatility concerns the spread of results. Qualitative labels do not supply a numerical standard deviation or a precise probability of exhausting a bankroll. More paying rounds also need not mean more profitable rounds: a $2 round returning $0.50 still loses $1.50.
The catalogue contains a six-game disagreement between its VARIANCE and VOLATILITY RATING fields. Those disagreements are shown in the game table. They should not be rewritten as selectable Low, Medium or High versions without a configuration record linking each version to its own return and rules.
The source’s MAX WIN (SIM) label is preserved deliberately. Its entries are useful catalogue specifications, but the file does not define whether SIM means the largest simulated observation, a configured award cap, or another measurement. The rules must establish the contractual limit, its wager basis and the treatment of unfinished bonus play. A 250× feature price must not automatically be substituted for the reference bet when applying a maximum multiplier.
The previous four-profile Egypt Apocalypto table is not supported by this workbook. Its single recorded entry gives 96.00% RTP, Medium in both volatility fields and a 20,000× MAX WIN (SIM) value. This does not prove that other configurations do not exist; it limits the specification claimed here to the one supplied.
The hit-frequency information also has limits. Necro Party’s hit-frequency cell is blank, and some other cells mix decimal fractions, percentage strings and unexplained numerical forms. No missing or ambiguous frequency has been converted into a precise bonus probability in this review. A maximum award, a bonus-trigger interval and a hit frequency are different quantities.
Comparing Games and Modes Fairly
Compare the same unit of expenditure and an identifiable configuration. For fixed planned amounts Wi wagered at their applicable returns ri, the combined theoretical return is Σ(Wiri) ÷ ΣWi, provided the total is positive. An unweighted average of titles describes only an equal-wagering mixture, not the return of an entire provider.
Finally, a booster’s price matters as much as its stated increase in feature frequency. A change in the probability of individual activator symbols does not automatically establish the same proportional change in a complete bonus trigger. A per-spin improvement is not a per-dollar improvement unless the extra cost is included.
Necro-Party
Introduction
Necro Party is a 7Rings Gaming video slot played on a five-column, five-row field with 20 prescribed paylines. The cartoon graveyard setting includes spellbooks, stitched dolls, horned skulls, daggers, poison bottles, and stone symbols. Its tilted playing surface gives the game a different appearance from conventional vertical reels, but the distinction that matters mathematically is in the bonus: certain wild symbols remain in place, and their multipliers can grow as the feature develops.
The published return to player is 96.40%, equivalent to a 3.60% house edge. The published volatility classification is Medium. These are reported game specifications; the arithmetic and payline analysis below are separate calculations, not a claim to have independently reconstructed the developer’s probability model.

The playing field and paylines
The game uses the 20 paths shown in its line diagram. A five-by-five field does not, by itself, mean that every possible route across the field pays. There are 5⁵ = 3,125 possible selections of one position from each column, but Necro Party documents 20 specific paylines rather than a 3,125-ways system.
The first five lines are horizontal. The remaining lines include diagonals, V-shaped patterns, inverted V-shaped patterns, and alternating paths. The paytable lists three-, four-, and five-symbol awards. A collection of matching symbols somewhere on the field is not, by itself, proof of a winning line; the game’s prescribed paths and settlement rules still apply.
All 20 prescribed paylines, in the numbering used by the game.
Why a wild’s position matters
The line diagram permits a useful calculation without knowing the reel strips or symbol probabilities. Count how many of the 20 paylines pass through each square. Numbering rows from top to bottom and columns from left to right gives the following table:
| Position | Column 1 | Column 2 | Column 3 | Column 4 | Column 5 |
|---|---|---|---|---|---|
| Row 1 — top | 4 | 2 | 2 | 2 | 4 |
| Row 2 | 4 | 5 | 4 | 6 | 4 |
| Row 3 | 4 | 5 | 8 | 5 | 4 |
| Row 4 | 4 | 6 | 4 | 5 | 4 |
| Row 5 — bottom | 4 | 2 | 2 | 2 | 4 |
Original calculation from the game’s 20 payline diagrams.
The center position belongs to eight lines: 3, 6, 7, 8, 9, 14, 17, and 20. Some other positions belong to only two. Each column totals 20 incidences, because each line uses exactly one position in each column. The complete field therefore contains 20 × 5 = 100 line-position incidences, averaging four per square.
This helps explain the appeal of locking a wild in a position shared by several lines. It does not establish that the center wild is four times as valuable as a wild on a two-line square. The symbols elsewhere on each line, the multiplier, the remaining bonus spins, and the payout rules also matter. Line coverage is a count, not a win probability or an expected-value estimate.
Symbol paytable
The following paytable lists the displayed awards for three, four, and five matching symbols. Symbol names other than Brain are descriptive labels for identifying the artwork. The five stone designs are listed separately even though they share the same displayed pay schedule.
Amounts are reproduced as displayed, not labeled as multiples of the total wager. In the original layout, “x3,” “x4,” and “x5” indicate the number of matching symbols; they are not additional factors to multiply into the adjacent award.

| Symbol | 3 matching | 4 matching | 5 matching |
|---|---|---|---|
| Brain wild | 5.00 | 10.00 | 20.00 |

| Poison bottle | 1.00 | 2.00 | 4.00 |
| Cross stone | 0.50 | 1.00 | 2.00 |
| A-marked stone | 0.50 | 1.00 | 2.00 |
| Omega stone | 0.50 | 1.00 | 2.00 |
| Circle-and-cross stone | 0.50 | 1.00 | 2.00 |
| Star-marked stone | 0.50 | 1.00 | 2.00 |
Source: the three original paytable screenshots.
The accompanying gameplay capture shows a 2.00 FUN wager. However, the cropped paytable images do not show the selected bet at the same time. Preserving the original display values avoids treating the relationship between those separate captures as an established payout-denomination rule.
For illustration, if the paytable was displayed at that same 2.00 FUN reference bet, the five-Spellbook award of 12.00 would equal 12.00 ÷ 2.00 = 6 times the reference bet. The five-Brain award of 20.00 would equal 10 times the reference bet, and the five-stone award of 2.00 would equal the reference bet. Those divisions are exact; the shared-bet assumption is stated rather than hidden.
The raw paytable does support comparisons that do not require a wager denomination. Five Spellbooks pay six times the five-stone award, because 12.00 ÷ 2.00 = 6. Likewise, the five-Brain award is ten times the five-stone award. These ratios describe awards, not relative symbol frequencies or contributions to RTP.
Wild symbols and multipliers
The game’s individual help entries identify the following five wild appearances. A useful way to describe them is one wild without a multiplier, followed by four multiplier-bearing categories.
The five wild appearances listed in the game help, including four multiplier-bearing categories.
| Wild appearance | Multiplier stated in the help |
|---|---|
| Brain | No multiplier |
| Worm | 2×–5× |
| Frog | 6×–9× |
| Satyr | 10×–14× |
| Gold Satyr | 15× and above |
The Brain’s lack of an additional multiplier does not mean that it has no value. It is identified as a wild, and it has its own matching-symbol awards in the paytable. The matching-symbol award and an additional wild multiplier are different pieces of the payout calculation.
The listed ranges are categories, not probability distributions. For example, “2×–5×” does not tell us that 2, 3, 4, and 5 are equally likely. It would therefore be unjustified to assign the Worm a 3.5× expected multiplier merely by averaging the endpoints.
A worked example from the game help
The game’s illustration shows a horizontal line of Omega symbols completed by a wild, with the calculation 2.00 × 5 displayed above it. The resulting illustrated line award is:
2.00 × 5 = 10.00.
The illustrated line pays 2.00 × 5 = 10.00 in the displayed units. This is not a statement of the total spin payout.
That is the award for the illustrated line, in the displayed units. It does not establish the total payout for the whole spin. Other winning lines, if any, must be accounted for under the game’s settlement rules.
Net profit is a separate calculation. For a hypothetical paid round costing 2.00 and returning a total of 10.00, the net profit would be 10.00 − 2.00 = 8.00. When evaluating a bonus purchased for a larger amount, the correct cost to subtract is the purchase price. A reference bet used to scale awards is not a substitute for the amount actually paid.
Free spins and the Pentagram feature
The tutorial states that three or more scatters start the Bonus Game and that each triggering scatter becomes a wild that remains until the feature ends. The published initial free-spin awards are:
| Triggering scatters | Initial free spins | Triggering symbols becoming persistent wilds |
|---|---|---|
| 3 | 6 | 3 |
| 4 | 8 | 4 |
| 5 | 8 | 5 |
The game tutorial describes demon wilds, persistent triggering wilds, and the Pentagram feature.
Four and five scatters have the same stated initial spin count, but five scatters supply one more persistent starting wild. Equal initial spin counts therefore do not imply identical starting bonus states.
During the bonus, a Pentagram appears on the field each spin. The tutorial explains that wilds landing on it remain for the rest of the feature and can increase their multipliers. The launch description specifies one-step multiplier increases. An increase from 4× to 5× is an addition of one to the multiplier, not a doubling to 8×.
The useful distinction is between an ordinary wild that helps on a particular spin and a persistent wild that can participate in later spins. A useful position secured early has more subsequent opportunities to contribute than the same position secured just before the feature ends. That observation does not require assuming that every opportunity produces a win.
Nor should the term “random position” be silently replaced by “each of the 25 positions is equally likely.” The supplied material does not establish a uniform selection rule. Consequently, the probability of a favorable Pentagram placement cannot be calculated simply by counting visible wilds and dividing by 25.
Boosters and purchased bonuses
The game help lists four optional paid features. Two modify play, while two guarantee bonus entry. The help also states that availability is jurisdiction-dependent. The price ratios below are corroborated by a captured in-game purchase menu displaying a 3.00 FUN reference bet and prices of 9.00, 150.00, 300.00, and 750.00 FUN.
Let b denote the reference bet displayed in that menu.
| Option | Price relative to b | Price at a hypothetical $1 reference bet | Stated function |
|---|---|---|---|
| FS Booster 5X | 3b | $3 | Increases the landing chance of bonus activators by five times |
| Game Booster | 50b | $50 | Increases game-feature activity and bonus-activator appearances |
| Warm-Up Ritual | 100b | $100 | Guarantees bonus entry with three starting wilds |
| Hellfire Bash | 250b | $250 | Guarantees bonus entry with four starting wilds |
Functions: in-game help. Price ratios: in-game purchase-menu capture.
These prices are different from the selected reference bet. At a 0.20 reference bet, for example, Warm-Up Ritual costs 20.00 and Hellfire Bash costs 50.00. The latter is the same expenditure as 250 ordinary wagers of 0.20. Equal expenditure does not make the payout distributions of those alternatives identical.
The difference between the two guaranteed-entry options is not just the price or the number of wilds in isolation. A fair comparison would require their complete bonus distributions and their own applicable RTPs. An additional starting wild does not, by itself, establish better value per unit paid.
What the booster wording does — and does not — establish
The supplied FS Booster text describes a fivefold increase in the landing chance of bonus activators. That wording should not automatically be turned into an exact fivefold increase in the probability of completing a bonus trigger. A trigger requires the qualifying combination, and the probability of that combination depends on how the symbols are generated.
Accordingly, the rules shown are not sufficient to calculate an exact bonus-trigger rate per dollar. Neither five times as many triggers per dollar nor any other precise improvement ratio follows from the label alone. The booster also does not promise five times the RTP or five times the profit.
The 96.40% RTP used in this review is not automatically assigned to every paid option. Separate feature prices do not prove that the modes share one return. Without the applicable mode disclosure, multiplying each purchase price by 3.60% would present an unsupported expected-loss figure.
RTP and house edge
Using the published 96.40% RTP, the implied house edge is:
100% − 96.40% = 3.60%.
For a fixed amount of wagering W at that applicable return:
Expected gross payouts = 0.964 × W.
Expected net loss = 0.036 × W.
| Total wagering | Expected gross payouts | Expected net loss |
|---|---|---|
| $100 | $96.40 | $3.60 |
| $1,000 | $964.00 | $36.00 |
| $10,000 | $9,640.00 | $360.00 |
For example, 500 paid rounds at $2 each produce $1,000 in wagering and an expected loss of $36 at this return. Individual sessions can finish far above or below that expectation. The calculation is not a forecast that a particular player will finish with a particular balance.
Wagering also differs from the initial deposit. Returned money can be wagered again, so a deposit can support a much larger cumulative amount of betting. RTP applies to the relevant amount wagered, not simply to the original amount placed in the account.
For an ordinary paid round that triggers free spins without a further charge, its bonus payouts belong to that paid round’s return. They are not free money outside the RTP calculation. Conversely, the reference bet should not be counted as a fresh expenditure on every no-additional-charge free spin.
Volatility and hit frequency
Necro Party’s published volatility classification is Medium, and its published hit frequency is 26.91%.
Volatility concerns how widely payouts vary, not merely how often a paying result occurs. A qualitative label does not provide the numerical standard deviation needed to calculate a confidence interval for a session, a probability of doubling a bankroll, or a probability of exhausting a specified bankroll.
Hit frequency must also be distinguished from the frequency of a net profit. A paid round costing 2.00 and returning 0.50 loses 1.50, even though it produces a payout. Thus a percentage describing hits cannot be treated as the percentage of rounds that leave the player ahead without checking how the provider defines a hit.
The distinction matters especially with purchased features. A feature can return a conspicuous amount and still lose money relative to its price. For a hypothetical 250.00 purchase returning 150.00, the net result is −100.00, regardless of how the game presents that payout.
A useful mental separation is: RTP describes the average return per unit wagered; hit frequency describes how often a defined event occurs; volatility describes dispersion. None is a substitute for the others.
Maximum win
The advertised maximum is 10,000×. This is a quoted game specification, not an independently calculated frequency of reaching that award.
The Gold Satyr help entry’s “15× and above” describes a wild-multiplier category. It does not establish an unlimited cash payout. The multiplier attached to a symbol, the reference wager used to scale awards, the price paid for a feature, and the maximum payable award are distinct quantities.
In particular, a 250-times-reference-bet purchase should not automatically be used as the denominator for the advertised maximum. The applicable maximum-win clause must define that basis and the treatment of any unfinished bonus. The supplied screenshots do not establish those settlement details, so no dollar-valued maximum or probability of hitting the cap is asserted here.
What can be calculated from the supplied material?
The paytable gives awards conditional on particular combinations. The line diagrams give the prescribed paths. Neither supplies the complete probabilities of the outcomes.
To independently reconstruct RTP, one would need the symbol-generation probabilities or equivalent reel information, together with the complete rules governing wilds, bonus transitions, purchased features, and payout limits. For a complete paid round with gross payout R and cost b, the basic calculation is:
RTP = E[R] ÷ b.
The bonus must be included in R when it is part of that paid round. Reading the paytable alone cannot recover E[R], because the awards still need their probability weights.
The 20 lines must not be treated as 20 independent trials either. They share positions and wilds. Expected line awards can be added without assuming independence, but the spread of their combined result depends on how they move together. That is another reason a numerical volatility calculation cannot be reverse-engineered from the paytable and line count alone.
Assessment
Necro Party is more distinctive for what persists between bonus spins than for what appears on a single spin. The documented interaction between persistent wilds, their multipliers, and the prescribed paylines gives the bonus a developing structure. The eight-line center position is a concrete example of why the placement of a persistent symbol can matter, although it is not enough to determine that symbol’s expected value.
The financial assessment is more restrained. The stated 96.40% return implies a 3.60% house edge in the applicable configuration. A more frequent feature is not necessarily a better-returning wager, an extra starting wild does not by itself justify a higher price, and a large displayed award is not necessarily a net win.
The appeal is therefore the bonus mechanics and presentation, not a demonstrated mathematical advantage. The useful comparisons remain the applicable RTP, the full amount charged, and the distribution of results—not the size of a multiplier graphic alone.
Leaderboards, Replays and Hot/Cold Indicators
7Rings’ public product presentation and the supplier’s correspondence describe an engagement layer of leaderboards, Big Win highlights, Hot/Cold indicators and cross-game navigation. These can help readers discover games or understand feature sequences. They should be assessed separately from the mathematics of a wager.
Hot and Cold Are Descriptions, Not Predictions
A Hot/Cold label needs a definition before it can be interpreted. If it is based on recent payouts divided by wagers, it reports an observed return over a sample period, not the theoretical RTP. The supplied catalogue does not disclose that methodology, its reporting window or its aggregation rules, so this review does not assume a particular formula.
A large award can dominate a small sample. Interpretation also depends on the number of paid rounds, total wagering, bet sizes and the mixture of purchase modes. For independent outcomes under the same configuration and equivalent game state, recent wins do not improve the next wager and recent losses do not make a win due.
Actual retained features are different. A wild, multiplier or other state carried forward by the rules may affect subsequent play. That is a rule-based state effect, not a reason to infer an advantage from a historical Hot/Cold label.
Big-Win Replays and Leaderboards
A replay can show the order in which a bonus acts, but highlights selected for unusually large awards are not a representative sample. Estimating an event’s frequency requires its occurrence count and the total number of comparable trials; a set of spectacular successes supplies neither a fair sample nor a reliable denominator.
Cash-win rankings can favor larger stakes. Rankings by bet multiples reduce that particular issue, but players making more attempts still have more opportunities to record an extreme result. Prize-bearing competitions require their own eligibility, scoring and reward rules. A leaderboard is not automatically an additional percentage of game RTP.
Promotions, Language Support and Demos
The catalogue marks Free Spins Promotions as available for the 27 Slot entries and unavailable for the two arcade entries. Prize Drops Promotions and Tournaments are marked In progress throughout the file. Those are statuses in the supplied snapshot, not confirmation that a particular casino currently offers the promotions; the presence of a ranking widget does not settle that question.
There are 18 localization entries marked YES across the catalogue, including English and the separate English (Social) entry. These are localization entries, not 18 necessarily distinct languages. Actual availability remains a matter of the installed game and host site.
The free-play Necro Party section on this page is useful for learning controls and inspecting the rules without a real-money wager. Demo results do not independently establish RTP or guarantee that another casino uses an identical mathematical configuration. Other titles can be explored through the official 7Rings game catalogue.
For practical comparisons, check the ordinary stake, the full charge for a selected mode, the paytable denomination, the applicable RTP and the maximum-award rule. Evaluate the complete paid round, including any attached free spins, rather than the most conspicuous single award.
Source Quality and Verification
This review uses the supplier’s General Game Catalog as its primary specification source. It is more informative than a list of promotional headline figures because it separates ordinary play, ante, Game Booster and purchases. It also contains conflicts, blanks and mismatched demo hyperlinks, which are not silently repaired by borrowing figures from unrelated versions.
The plain-language game profiles summarize the catalogue’s features; the reference graphics reproduce catalogue information and are labeled accordingly. They are not official game screenshots, symbol paytables or payline diagrams. The detailed Necro Party section retains its separate screenshot-based illustrations. The workbook itself does not supply complete symbol awards or line maps for the other games.
A listed RTP is not an independent mathematical certification. Verifying it requires the complete outcome model and feature rules, or an applicable testing report. Likewise, the catalogue’s jurisdiction flags are not substitutes for regulatory records identifying an entity, product and approval scope. Supplier documentation, game testing and the host casino’s handling of player funds are separate questions.
Unresolved differences have been retained where they matter: six volatility-field conflicts, a few line/cluster-count conflicts, incomplete maximum-award definitions and selected purchase ambiguities. The catalogue supports the values shown here; it does not justify inventing the missing rules or claiming that every casino uses one universal configuration.
Assessment
7Rings offers meaningful variety within the supplied portfolio: sticky features in Wild Bite, a Mini Slot and gamble in Bar of Fate, wild and multiplier spawning in Dead Gun, bidirectional lines in Zombzilla, and two distinct arcade formats. The catalogue also spans an ordinary-play RTP range of 96.00%–96.66%, with material differences between some paid modes.
The most useful distinction is therefore not simply which game advertises the largest multiplier. It is what the chosen mode costs, which return applies, how results are distributed and which rules carry state forward. The strongest part of the offering is its mechanical variety; the documentation’s conflicts limit how precisely some configurations can presently be described.
Judge the installed game and its price, not a highlight reel or a Hot/Cold label. A larger maximum is not a higher expected return, a feature purchase is not a guaranteed profit, and a supplier’s stated RTP is not a prediction of a single session.
