Lucky 7 -- Slotastic Version

Introduction

I noticed Lucky 7 at the Slotastic casino in June 2025. It is a simple game based on betting on the draw of a single card.

It should not be confused with the version of Lucky 7 by betgames.tv, which is based on a draw of keno balls.

The game uses one or more 52-card decks. The number of decks used does not matter.
Aces are low. Otherwise, cards are scored according to poker value.
The following bets are available and what they pay:
- 7 Down -- Wins on A-6 -- Pays 1 to 1*.
- 7 Up -- Wins on 8-K -- Pays 1 to 1*.
- 7 -- Wins on 7 -- Pays 11 to 1.
- Even -- Wins on 2, 4, 6, 8, 10 or Q -- Pays 1 to 1.
- Odd -- Wins on A, 3, 5, 7, 9, J, K -- Pays 0.8 to 1.
- Red -- Wins on any red card -- Pays 0.9 to 1.
- Black -- Wins on any black card -- Pays 0.9 to 1.

*: Bets on 7 Down and 7 Up lose half on a 7.

The following table shows my analysis of the 7 Down and 7 Up bets. The lower right cell shows a house edge of 3.85%.
