The rule is like dice games. The players will get two dices with the points from 1 to 6 x 2.
The player can choose numbers 2 to 6, 7 , 8 to 12. The odds will be 1 : 1 to 1 : 4.
Also, the players can choose to add the points of two dices, which is the numbers 2 to 12. The odds will be 1 : 5 to 1 : 26.
There are 13 places that you can place a bet. The player can place max 12 bets in each round, which is very crazy!
The players only need to afford 1/13 of a chance to lose. The rest depends on the betting amount and odds. I believe there will be a good rate of return.
