  • Patent number: 7185889
    Abstract: A method of playing a wagering game where each player is dealt a plurality of playing pieces. Each player will review the playing pieces. A first player will make a call of a total quantity of a numeric suit on all playing pieces. Each successive player will make a next call of the total quantity of the numeric suit of all playing pieces unless another player challenges that the call is incorrect. For each successive call, the next call has to be one where either the quantity of the numeric suit increases, a value of the numeric suit increases and the quantity stays the same, or both the quantity and the numeric suit increases. After a challenge is made, each player will display the playing pieces. A winning player is decided by seeing if the total quantity of the numeric suit of all playing pieces by a last player to make a call is correct or if the player challenging is correct.
