Gamesys Review

Introduction

Gamesys N.V. is an online betting firm that was founded in 2004, and is headquartered in the Netherlands Antilles. The company seems to be completely separate from the UK based Gamesys, as this particular betting firm only provides gaming software for BetVoyager and BetRaiser, while the UK firm oversees the brands Virgin Casino, JackpotJoy, and Caesars Casino.

The firm is licensed by the Government of the Netherlands Antilles to operate as an online betting software developer, and specializes in developing casino games, a rake free poker product as well as a sportsbetting exchange for the above-mentioned operators.

Gamesys N.V. has a pretty decent reputation among punters, as do the casinos they provide services to. While it may not be hailed as the flashiest of software providers, Gamesys does have a good tool that allows players to audit results for fairness.

When Internet gambling first started, any given casino either created its software themselves or got the software from one provider exclusively. Examples include Realtime Gaming, Microgaming, and Playtech. As I write this in 2015, that business model is fading away and moving toward multiple software brands in the same casino.

Gamesys is one of those companies that does not demand exclusivity. Their games can be found mixed together with those of other companies at Internet casinos which like to pick and choose their games from multiple providers.

This review is largely based on the games Gamesys provides to the BetVoyager casino. BetVoyager seems to take in a mixture of games from Gamesys and BetSoft. At first, it was frustrating for me to tell them apart. However, I later learned a simple way to identify a Gamesys game. They all have a button that says "Randomness Control" or just "RC." Some also display a long 64-digit sequence of apparently random looking characters at the top. This is all part of their "fairness guarantee," which I'll explain next.

Fairness Guarantee



A complaint I hear a lot about Internet gambling is it can't be trusted, because the casino has total control over the outcome. While I believe that the vast majority of major Internet casinos play a fair game, gamblers pretty much do have to take it on faith that the casinos are playing fairly. Until now.

As far as I know, Gamesys is the only provider of Internet casino software to predestine the outcome before the player makes a wager. For example, in roulette, the outcome of 23-red would be known in advance. So, the casino can't make the ball land in black if you bet on red. How do they do this, you ask?

Basically, the casino tells you the outcome in a foreign language, but they don't tell you which foreign language. After the bet is made, they reveal the language, so you can translate the outcome and confirm it matches.

For example, in roulette, it might be 23-red. In video poker, it might be the next ten cards in the decks, which is the most you would need. Then they add a bunch of random characters. Then this outcome gets translated into a 64-digit code called a "checksum." The player can see this code before making his bet. After the bet is adjudicated, the player may click on a check mark to see the text that showed the predestined outcome. The player may then click "calculate checksum" to translate it into a checksum. The player will be able to see that it matches the checksum given before the wager was made. There are other independent sites the player may also use to translate text to the same kind of checksum, for the skeptics out there.

I am a big advocate of open and honest gambling, so I applaud what Gamesys is doing in the interests of fair gaming.

Zero House Edge



It seems every game by Gamesys has a regular and a "zero house edge" version. What is the catch? The player must pay a 10% commission on any net gambling win per session. A "session" is defined as ending after a period of no activity of an hour or 24 hours, whichever happens first.

Be warned that not every bet in the "zero house edge" games has a zero house edge. Even the ones that are supposed to don't always, especially the blackjack and poker variants. Throughout this page I address the odds on both the standard and "zero house edge" versions.

As a general rule, I strongly recommend recreational players play the true "zero house edge" games, especially over long gambling sessions. In roulette, for example, making even money bets, the odds are better in the "zero house edge" version with as little as two bets compared to the standard single-zero version. The 10% commission may sound like a lot, but it is much worse to play a house edge game and let the casino advantage grind you down every bet.

Following is my general advice for playing Zero House Edge games:

  • Make sure the edge truly is zero, or very close to it.
  • Make low-volatility bets, preferably anything that pays even money.
  • Keep your bet range tight. The best strategy is to flat bet.
  • Try to clump your gambling into as few sessions as possible. For example, it is better to have one two-hour session than two one-hour sessions.

Table Games

Gamesys has a wide variety of table games. Most are classic games but some they created themselves. The rules are generally more liberal than average.

Most tables let the player play up to four spots, including the poker variants. It is unusual in the Internet gambling business to let the player bet more than one spot in poker-based games, because it gives the player additional information via seeing more cards. In some games, where seeing extra cards is especially powerful to the player, the casino will force the player to make a blind raise/fold decision in the third and fourth spots.

Somebody at Gamesys must love Caribbean Stud Poker variants. They strangely don't have Caribbean Stud itself but have lots of variations of it that add extra features like switching cards, buying cards, taking insurance, and forcing the dealer to switch a card.


Baccarat


Punto Banco

Punto Banco -- Zero House Edge

Gamesys offers both punto banco and heads-up baccarat. Punto Banco and baccarat are pretty much the same game, just the language is different, so I will use my usual convention of titling games by their standard names.

To make matters more confusing, what they call "heads-up baccarat" is really Chemin de Fer. How is that different?, you might ask. Chemin de Fer is like baccarat, but allows free will in drawing cards as long as neither side has a natural 8 or 9. I feel that it is sufficiently different from baccarat to create a separate section for that game.

I would like to say "bravo!" to Gamesys for paying 9 to 1 on a tie in punto banco, which lowers the house edge from 14.44% to 4.84%.

There is, of course, a "zero house edge" punto banco game too. This features the following bets:

  • Banco bet with 2.75% commission, for a house edge of 0.03%.
  • Punto bet that pays 1.0282 to 1, for a player edge of 0.02%.
  • Egalite bet that pays 9.48 to 1, for a house edge of 0.28%.

Bet Voyager Hold 'Em


Bet Voyager Hold 'Em
 

Bet Voyager Hold 'Em is closely based on Casino Hold 'Em, with these rule changes:


  • The pay table applies to the Call bet instead of the Ante.
  • The pay table pays more.
  • The dealer qualifies with a pair of twos instead of fours.
  • If the dealer qualifies and the player wins, then the Ante will push.


I created a whole page devoted to Bet Voyager Hold 'Em. The bottom lines is that the house edge in the standard version is 1.68%, assuming optimal strategy. My computers are cranking away at the zero house edge version and should be finished on April 3.

There is also the same AA+ side bet as in Casino Hold 'Em, with a house edge of 2.97% and a "Zero House Edge" version.

Big Six


Wheel of Fortune
 

Gamesys calls this game Wheel of Fortune, but I believe that Big Six is the more common term, so am titling it that. There is both a standard and "zero house edge" version. The following table shows the probability of winning and house edge under the standard version. As you can see, every bet has the same house edge of 1/49 or 2.04%.

Gamesys Wheel of Fortune

Bet Pays Number
on Wheel
Probability House
Edge
1 1 24 0.489796 0.020408
3 3 12 0.244898 0.020408
7 7 6 0.122449 0.020408
15 15 3 0.061224 0.020408
23 23 2 0.040816 0.020408

Joker 47 1 0.020408 0.020408
Total 49 1.000000


In the "Zero House Edge" version the rules are the same, except:

  • If the wheel stops on the Logo, then any bet, other than the Logo, shall push, instead of lose.
  • If the wheel stops on the Joker, then any bet on the Logo shall push, instead of lose.


By changing one stop from a loss to a push on all bets, that does indeed make the house edge exactly 0.00%.

Blackjack and Variations


Diamond Blackjack

European Blackjack

American Blackjack

Doublet Blackjack

All due credit to Gamesys for creating some new blackjack games I've never seen before. The new ones incorporate some unusual rules that the rules table below doesn't support, so let me make special mention of them:

Doublet Blackjack



The only unusual rule is Double Down Rescue. This means the player may surrender after doubling. This creates an interaction effect with its European no peek rule, which my normal model doesn't support, so I had to do a custom analysis of it. Since I did that, I created a whole page devoted to Doublet Blackjack.

Diamond Blackjack



This game is similar to Super Fun 21. A major difference is that there is no hole card, making the rule allowing surrender at any time much more powerful. However, they don't allow some other things that Super Fun 21 does, evidently to compensate. Here are all the special rules the table below doesn't indicate:

  • Player blackjack is an automatic winner.
  • Player blackjack in diamonds pays 2 to 1. All other blackjacks pay 1 to 1.
  • Player may double at any time.
  • Player may surrender at any time, including after splitting.


I find the house edge on the standard version of Diamond Blackjack to be 1.24%. In the "Zero House Edge" version some blackjacks pay more, lowering the house edge to 0.39%.

For more information, please see my page on Diamond Blackjack.

Zero House Edge



Every blackjack game has a "zero house edge" version. They only rule changes are that blackjacks pay more. The additional blackjack win depends on the game, as follows:

  • American Blackjack: Ace-king blackjack in spades pays 4 to 1. This lowers the house edge by 0.19%, from 0.29% to 0.10%.
  • European Blackjack: Ace-king blackjack in spades pays 7 to 1. This lowers the house edge by 0.41%, from 0.45% to 0.04%.
  • Doublet Blackjack: Any blackjack in spades pays 2.5. This lowers the house edge by 0.30%, from 0.38% to 0.08%.
  • Diamond Blackjack: Ace-king in diamonds blackjack pays 7.5 and any other blackjack in diamonds pays 4. This lowers the house edge by 0.85%, from 1.24% to 0.39%.

The following table shows the Blackjack and Variations games available in alphabetical order.

Blackjack Switch


Blackjack Switch
 

Gamesys follows the usual Blackjack Switch rules, with these specifics:

  • Six decks.
  • Dealer stands on a soft 17.
  • No dealer hole card. Player loses everything against a dealer blackjack after doubling or splitting.
  • Switched blackjack counts as 21 points.
  • No surrender.
  • Double after split allowed.

It goes without saying that the player may switch cards between hands and that a dealer total of 22 will result in a push instead of a win. Please see my Blackjack Switch page if you're not familiar the game.

Previously, the closest set of rules I've heard to these were found in Russia. They follow the same rules as Gamesys, except in Russia they allow surrender. The house edge under the Russian rules is 0.20%, according to the game owner.

I don't have a convenient way to determine the value of surrender in a no hole card game of Blackjack Switch. I do know that the value of early surrender in conventional blackjack is 0.63%. However, I assume that it would be less in Blackjack Switch because the player can often switch out of bad hands. I roughly guess the value of early surrender in Blackjack Switch to be about 0.27%. That would make the house edge under the Gamesys rules 0.20% + 0.27% = 0.47%.

In the "zero house edge" version an ace-king of spades blackjack pays 2 to 1. The probability of that is 0.07%, which is also how much it is worth to the player. Thus, the "zero house edge" house edge is 0.39%.

I want to stress that these figures should be considered rough, which is something I don't say very often. Blackjack Switch is a tough game to analyze and I've spent weeks on this software review as it is.

The Super Match bet follows the usual 5-8-40 pay table for a house edge of 2.55%.

Casino Hold 'Em


Casino Hold 'Em
 

Gamesys follows the standard rules for Casino Hold 'Em as well as the most common 1-2-3-10-20-100 pay table that can be found in land casinos. This pay table results in a house edge of 2.16%.

There is also an AA+ side bet pay table, which I haven't seen before. It goes 7-7-8-10-20-30-40-50-100, for a house edge of 2.97%.

The "Zero House Edge" version of the game follows a 1-2-3-17-49-100 pay table for a house edge of 0.35%.

Casino War


Casino War
 

Gamesys generously follows the liberal "bonus" rules of Casino War, where the player gets a bonus of three times his Ante bet in the event of a tie after a tie. I haven't seen a bonus that generous since Starnet software went out of business some 15 years ago. This bonus lowers the house edge from the usual 2.88% to 1.24%. Six decks are used.

Catch a Wave


Catch a Wave
 

Catch a Wave was played at the Foxwoods casino in Connecticut from 2001 to 2005. I thought it went the way of the dodo bird until I saw Gamesys decided to bring it back from the dead.

For the benefit of the old-timers like me, Catch a Wave is loosely based on the old TV game show Card Sharks. The object is to predict whether the next card in the shoe is higher or lower than the previous card, up to six times. The player also has the option to stand along the way, in which case the dealer has the chance to beat the player.

Gamesys follows the same rules, including eight decks, as Foxwoods did back in the day. If you follow my strategy, the house edge is 0.50%.

Chemin de Fer

Gamesys calls this game Heads Up Baccarat, but I'm big on titling games by their conventional names, which in this case is chemin de fer. Before going further, let me explain that when I write about baccarat and chemin de fer I refer to those playing the game in lower case and the bets in upper case, in an effort (probably a failed one) to avoid confusion.

That said, chemin de fer is the same as baccarat, with these changes:

  • The game is player-banked.
  • Apart from a natural 8 or 9 ending all further drawing, both the Player and Banker have free will in taking a third card. The Player must still act first and any third card is dealt face up.
  • At Gamesys, the casino charges a 3% commission on Banker wins (I'm not sure what they do in Monte Carlo).
  • The turn to bank alternates among the players.

The optimal strategy in this game is to randomize the following decisions:

  • Player total of 5.
  • Banker total of 6, if the player stood.
  • Banker total of 5, if the player hit and got a 4.
  • Banker total of 3, if the player hit and got a 9.

Assuming two perfect logicians played, well versed in game theory, the expected loss on the Player bet is 1.28% and on the Banker bet is 0.10%, after the 3% commission. You can find the optimal strategy in my Chemin de Fer page, which I updated thanks to Gamesys.

Craps


Craps
 

Gamesys generously follows the Australian/UK odds in craps, which have more generous wins than the stingy American rules. Here is a summary:

  • Pass and come bets are 2x odds.
  • Don't pass and don't come are also 2x, relative to the amount bet.
  • The field is the liberal version, paying 3 to 1 on the 12.


The following table shows the odds of all the other bets.

Buy 6,8 144 to 125 45.45% 2.18%
Lay 6, 8 4 to 5 54.55% 1.82%


Zero House Edge



Like many games, Gamesys has a "zero house edge" version of craps. It isn't zero on all the bets, but here are the ones they changed:

  • Odds: The pass, come, don't pass, and don't come are all infinity x odds, subject to table limits. In the free version of the game, I couldn't bet more than $200 on the odds, so for a $1 line bet the odds would be effectively 200x. That would make the overall house edge 0.01%.
  • Buy and Lay: No commission, paying fair odds.


Dice


Dice
 

This is another game that has only a "zero house edge" version. For information, please see my page on Dice.

Double Exposure


Double Exposure
 

Gamesys follows these double exposure rules:

  • Six decks.
  • Dealer stands on soft 17.
  • Tied blackjack is a push.
  • Double on hard 9 to 11 only.
  • Split three times, including aces.
  • Double after split allowed.

According to my math, the house edge under these rules is 0.51%.

The "zero house edge" version pays 8 to 1 for a winning ace and king of spades. This lowers the house edge by 0.52% for a player advantage of 0.01%.

Let it Ride


Let it Ride
 

The Gamesys Let it Ride game plays like the one seen in land casinos, except the player makes one bet to start and has two opportunities to add to it, as opposed to making three bets to start and having two chances to pull them back. Mathematically, it is the same thing.

A more liberal pay table than the standard one in U.S. casinos is followed. To be specific, the pay table goes 1-2-3-5-10-15-50-100-500, for a house edge of 1.99%.

The "zero house edge" pay table goes 1-2-3-6-11-15-52-110-250 for a house edge of 0.83%.

There is also the ubiquitous side bet on the final five cards that goes 25-40-50-70-200-500-1000 for a house edge of 5.92%.

For more information, please see my Let it Ride Appendix 3, which has the probability and return of both Gamesys Let it Ride pay tables, as well as lots of others.

Pachinko


Pearl Pachinko
 

This is a nicely done game. All I can tell you is the player shoots 100 pearls and tries to get them into shells for a chance at opening a treasure chest. There is both a regular and a "no house edge" version of the game. I'll take Gamesys at their word about the "no house edge," but on the regular version I have no idea what the odds are.

2+4 Poker


2 + 4 Poker
 

2+4 Poker is based on Caribbean Stud Poker, with three major differences:

  • The dealer gets six cards instead of five.
  • The dealer exposes four cards instead of one.
  • The player may buy a sixth card for the price of the Ante bet. This decision is made before the fold/raise decision.

The usual 1-1-2-3-4-5-7-20-50-100 pay table is followed.

As for the odds, it isn't often that I say this, but I have no idea. My compliments to the mathematician who figured this game out.

Like many other poker-based games by GameSys, there is a side bet based on the player's first five cards. It follows a 25-40-50-70-200-500-1000 pay table for a house edge of 5.92%.

The pay table in the Zero House Edge version is a little higher. The win for a four of a kind is increased from 20 to 25 and the win for a straight flush is increased from 50 to 57.

With no known strategy or analysis, play this one at your own risk.

6 Card Poker 1-2-5


6 Card Poker 1-2-5
 

6 Card Poker 1-2-5 is closely related to Lunar Poker. It is unique in that it is the only game in the Gamesys portfolio that is only in the "Zero House Edge" category. It doesn't have a standard version.

There is the usual Bonus bet, that follows a 25-40-50-70-200-500-1000 pay table for a house edge of 5.08%.

The player may play up to four spots, but the third and fourth must be played blind, with a forced raise.

For the full rules, please see my page on 6 Card Poker 1-2-5.

In the game itself, the link to the BetVoyager rules page doesn't work. Here is the correct link.

Caribbean Advanced Poker


Caribbean Advanced Poker
 

Caribbean Advanced Poker is the same thing as Caribbean Stud Poker, except the player gets to see two dealer up cards instead of one. The standard 1-1-2-3-4-5-7-20-50-100 pay table is followed. With optimal strategy, the house edge is a low 0.62% and the Element of Risk is 0.26%.

Like many other poker-based games by Gamesys, there is a side bet on the player's first five cards, which follows a 25-40-50-70-200-500-1000 pay table, for a house edge of 5.92%.

Finally, there is a Zero House Edge version of this game. The only difference is the pay on the full house is increased from 7 to 8 and on a four of a kind from 20 to 25.

For much more, please visit my page on Caribbean Advanced Poker.

Lunar Poker


Russian Poker
 

As far as I know, Gamesys is the only place where you can play Lunar Poker. However, they call it by its other name, Russian Poker. The standard 1-1-2-3-4-5-7-20-50-100 pay table is used.

As far as I can tell, the rules are the same as what is on my Lunar Poker page, except Gamesys offers one extra benefit — If the player switches one card only, and doesn't like it, he can keep switching (and paying) as much as he wants.

In the standard version, if the player has a three of a kind or better, then he can insure against the dealer getting a non-qualifying hand. The size of the insurance bet may up to half the potential win. If the dealer does not qualify, then the insurance bet will pay even money. If the dealer qualifies and beats the player, then the insurance bet will be a push. Otherwise, it will lose.

The player may play up to four spots. However, there are rules in place to avoid the player taking too much advantage of the additional information.

They also have a side bet based on the player's first five cards. That pay table goes 25-40-50-70-200-500-1000 for a house edge of 5.92%.

There is also a "zero house edge" version of the game. The only difference in the rules is that the player may insure up to the full value of a three of a kind or greater, instead of half.

For more information about this complicated game, please see the Bet Voyager rules for Russian Poker.

Oasis Poker


Oasis Poker
 

Oasis Poker is a variant of Caribbean Stud Poker, except that the player can exchange one or two cards, for a price. The standard 1-1-2-3-4-5-7-20-50-100 pay table is used.

As far as I can tell, the rules are the same as on my Oasis Poker page, except Gamesys charges only 1.5x the Ante to exchange two cards, as opposed to the usual 2x. All I can say about that is that the player should never switch two cards at a price of 2x. At a price of 1.5x, I just don't know. I hate to say this, but for now, you're on your own with that.

The player may play up to four spots. However, there are rules in place to avoid the player taking too much advantage of the additional information.

They also have a side bet based on the player's first five cards. That pay table goes 25-40-50-70-200-500-1000 for a house edge of 5.92%.

There is also a "Zero House Edge" version of the game. The only changes were an increase in the pay for a full house from 7 to 8, and on a four of a kind from 20 to 26. According to my math, that lowers the house edge from 1.04% to 0.70%, assuming no strategy changes and not factoring in the lower priced fee to change two cards. Maybe those two adjustments would lower the house edge by 0.70%, but I doubt it. Remember that the player must pay a 10% commission on any net gambling session win.

Poker Switch


Poker Switch
 

Poker Switch is based on the idea of Blackjack Switch. It is like playing two hands of Caribbean Stud Poker, except the player may switch the last card dealt to each hand for a price of Ante on both bets.

This is one of the few games I have not analyzed at all. I tip my hat to whatever mathematician tackled this one for Gamesys.

Just going off common sense, it would seem to me that a price of the Ante, on both bets, is a pretty steep price and would be likely rarely invoked under proper strategy. I'm sure there are exceptions, but the best use of the option would probably be to create a straight or higher in either hand.

There is also an Insurance feature, where the player can make a side bet with a three of a kind or better that the dealer will not qualify, to hedge against not getting paid on the Raise bet.

There is also the same 25-40-50-70-200-500-1000 side bet that I've seen in their other poker games, which carries a house edge of 5.92%.

Finally, they have a Zero House Edge version of this game too. The only changes that I can see are increasing the win on a flush from 5 to 6 and on a full house from 7 to 8. You will have to take their word on it that this does lower the house edge to zero.

Q Poker


Q Poker
 

Q Poker is very similar to Three Card Poker except:

  • Instead of having the option to make a Raise bet, the player may surrender half his Ante bet.
  • There is no Ante bonus.
  • There is a pay table for the Ante bet, with a straight or higher paying premium odds.

Another way to look at it is that the player now must win to collect the premium odds on a straight or higher, but those odds apply to the total amount bet.

Gamesys improves upon the usual 3-2-1.5 pay table seen in Macau with one that goes 4-3-2. The following table shows the probability and return of all possible outcomes. The lower right cell shows a house edge of 1.34%.

The PairPlus bets, or "Pair+" as Gamesys calls them, in Q Poker are the same as in Three Card Poker (see below).

Three Card Poker


Three Card Poker
 

Three Card Poker is played by the conventional rules except with more liberal pay tables. The following table shows the pay tables and house edge for the standard version.

Standard Three Card Poker

Hand Ante Bonus PairPlus
Straight flush 9 40
Three of a kind 8 32
Straight 1 6
Flush 0 4
Pair 0 1
House edge 1.56% 1.85%


The next table shows the same thing for the "Zero House Edge" version.

Zero House Edge Three Card Poker

Hand Ante Bonus PairPlus
Straight flush 12.5 42
Three of a kind 10 38
Straight 1 6
Flush 0 4
Pair 0 1
House edge 0.33% 0.00%


The PairPlus house edge isn't just zero to two decimal points, it is exactly zero. I must say I'm impressed that they found a pay table to achieve that.

Roulette


American Roulette

European Roulette

Multi-Ball Roulette

Roulette Express

No-Zero Roulette

I don't know why Internet casinos need to have so many different roulette games, but Gamesys is no exception. Following is a summary of the roulette games offered.

American Roulette



This game is played on a dreaded double-zero wheel. There is some good news in that single-number bets pay 36 to 1, instead of the usual 35. They also kindly don't allow bets on the 0-00-1-2-3 combination, which carries a house edge of 7.89%.

The house edge in this version of American Roulette is 2.63% on the single-number bets and 5.26% on all others.

European Roulette



This game follows the standard rules and is played on a single-zero wheel. Sorry, no losing half if the ball lands in zero, which I call "French roulette." The house edge on all bets in European roulette is 2.70%.

Multiball Roulette



This game is played on a single-zero wheel with one to three balls. If the player selects more than one ball, then whatever he bets is divided among the three balls. For example, if the player chooses three balls and bets $30 on red, then it will be like having three $10 bets on red, one for each ball. The bet amounts are conveniently evenly divisible by 2 or 3, depending on the number of balls.

The odds are the same as in single-ball European roulette, with a house edge of 2.70% on every bet.

Roulette Express



This game is similar to Multiball Roulette, except that the player may make parlay bets, called "Express Bets," based on the outcome of all three balls. For example, an Express Bet on red pays 8 to 1 and wins if all three balls land in red. Please note that each balls lands in a different number.

I felt there was enough to say about this game that I devoted a page to Roulette Express, which you may refer to for more information.

No-Zero Roulette — Zero House Edge



The title pretty much says it all. The standard roulette pay table is followed. With no zero, there is no house edge.

Please note that in all "Zero House Edge" games there is a 10% commission on the net gambling session win. Please see the top of this page for more details.

American Roulette — Zero House Edge



Single number bets pay 37 to 1. All others push on a zero or double zero. The house edge on every bet is exactly 0.00%.

European Roulette — Zero House Edge



Single number bets pay 36 to 1. All others push on a zero. The house edge on every bet is exactly 0.00%.

Single-Zero Roulette Express — Zero House Edge



The single-ball bets follow the rules for Zero House Edge European roulette, for a zero house edge.

The Express straight and neighbors bets pay 221 and 209 respectively, also for zero house edge. The other express bets carry a low house edge, but not quite zero. Please see my page on Roulette Express for more information.

No-Zero Roulette Express — Zero House Edge



The single-ball bets follow the standard roulette pay table. With no zero, there is zero house edge.

The column Express Bets pay 31.4 for no house edge. The other Express Bets carry a small house edge. Please see my page on Roulette Express for more information.

Sic Bo


Sic Bo
 

The pays in the Gamesys sic bo are pretty good, especially compared to other sic bo games. The following table shows the probability of winning and house edge on most of the bets. The "double" bet is the one that a particular number will occur at least twice. The "domino" bet is the one that two specific numbers will both occur.

Sic Bo — Standard Version

Bet Pays Combinations Probability House Edge
4 69 3 1.39% 2.78%
5 34 6 2.78% 2.78%
6 20 10 4.63% 2.78%
7 13 15 6.94% 2.78%
8 9 21 9.72% 2.78%
9 7 25 11.57% 7.41%
10 6 27 12.50% 12.50%
11 6 27 12.50% 12.50%
12 7 25 11.57% 7.41%
13 9 21 9.72% 2.78%
14 13 15 6.94% 2.78%
15 20 10 4.63% 2.78%
16 34 6 2.78% 2.78%
17 69 3 1.39% 2.78%
Specific triple 208 1 0.46% 3.24%
Any triple 34 6 2.78% 2.78%
Double 11 16 7.41% 11.11%
Domino 6 30 13.89% 2.78%


The bet on a specific number nicely pays 16 to 1 for a three of a kind, for a house edge of 1.85%.

Zero House Edge



Like many Gamesys games, there is also a "zero house edge" version. This pays the same for all the total bets, which I would avoid. However they do modify the odds on the other bets, as follows.

The single number bet pays 20 to 1 for a three of kind. As the following return table shows, that puts the house edge at 0.00%.

Single Number Bet — Zero House Edge

Bet Pays Combinations Probability Return
3 20 1 0.004630 0.092593
2 2 15 0.069444 0.138889
1 1 75 0.347222 0.347222
0 -1 125 0.578704 -0.578704
Total 0 216 1.000000 0.000000


The Domino bet puts the win for a pair and a singleton to 7 to 1. As the following table shows, that lowers the house edge to 0%.

Single Number Bet — Zero House Edge

Bet Pays Combinations Probability Return
Double and single 7 6 0.027778 0.194444
Two singles 6 24 0.111111 0.666667
Loss -1 186 0.861111 -0.861111
Total 216 1.000000 0.000000


The Double bet puts the win for a three of a kind to 35 to 1. As the following table shows, that lowers the house edge to 0%.

Single Number Bet — Zero House Edge

Bet Pays Combinations Probability Return
Triple 35 1 0.004630 0.162037
Double 11 15 0.069444 0.763889
Loss -1 200 0.925926 -0.925926
Total 216 1.000000 0.000000


These other bets also have a house edge of zero:

  • The any triple bet pays 35 to 1.
  • The specific triple bet pays 215 to 1.
  • The Small bet wins on three ones, twos or three.
  • The Big bet wins on three fours, fives, or sixes.


Slot machines


7 Wonders

The slot machines by Gamesys are the standard three-reel and five-reel variety. They look like what you would have seen in a land casino around the turn of the century. In other words, nothing especially fancy, but simple and down to business.

Three Card Baccarat


3 Card Baccarat
 

As far as I know, Gamesys is the only Internet casino software to offer Three Card Baccarat. In fact, the only other place I've ever seen the game anywhere is a few tables in Macau. Gamesys changes the word "three" to the numeral 3 and improves on the horrible odds offered by the Macau version of the game. Following are the particular bets available and a comparison between Macau and Gamesys:

  • Player: In Macau, the basic Player bet has a 5% commission, for a house edge of 2.41%. Gamesys kindly charges 3% only, for a house edge of 1.44%.
  • Tie: In Macau, the Tie bet pays 20 to 1 for a house edge of 20.80%. Gamesys was nice enough to bump the win up to 25 to 1, for a house edge of 1.94%.
  • Dealer Totals: In both Macau and Gamesys, the specific dealer total bets pay 8 to 1. The house edge ranges from 2.91% (on a tie of zero) to 11.87%.
  • Three Faces: As I point out in my page on Three Card Baccarat, the worst bet I've ever seen on a table game is the Three Faces bet, which pays 16 to 1 in Macau, for a house edge of 83.08%! Fortunately, Gamesys corrects this abomination by paying 96 to 1, for a house edge of 3.44%. Thank you!

Video Poker


Jacks or Better

Joker Poker (kings or better)

Double Joker Poker

Double or Nothing

Deuces Wild

Gamesys has a collection of six classic video poker games. All are multi-play, available in 1, 3, 5, 10, 25, and 50-play.

Be warned that the win for a royal flush is 400 per coin, as opposed to the usual 800, based on a max coin bet. In other words, there is no economy of scale in betting five coins per line. 400 is as good as it gets.

Every game comes in a standard and "zero house edge" version. As with all the other "zero house edge" games, the player must pay a 10% commission on his net gambling win per session.

A couple of the Zero House Edge games actually have a small player advantage, but our system goes only as high as a 0.00% house edge. Those two are:

  • Joker Poker (kings or better): Player edge of 0.02%.
  • Jacks or Better: Player edge of 0.01%.

The following table shows the Video Poker games available in alphabetical order.
