The game involves two players who play against each other. The players win based on a value that is calculated based on the cards. The value is not counted as in blackjack, but the sum must always be a single digit. The game can end in a draw.
Spectators can place their bets on who will win each hand. Different coefficients are dependant on who the spectator bets on. Betting on the house has the lowest ratio, 95 % of the value of the bet. Betting on the player has a coefficient of 100 %. Betting on a draw has a factor of 800 % or more.
