Analysis



The following table shows all the available bets, what they pay, the number of winning combinations out of 26,978,328, the probability of winning, and the return to the player. All wins are on a "for one" basis, meaning this is the total amount a winning bet will get back. Bets on a particular color may be made on yellow or black. To keep the table as short as possible, I listed each such bet once only and used the phase "chosen color" to mean the player may make this bet on yellow or black.

    I think the lovely dealers are the main reason for playing this game. That said, here are some screenshots of more of them. These, I believe, were taken with a previous study. The look of the game is a bit different now.













    • Lucky 5 — Another lottery game by the same company, with a draw of five balls out of 36.
