Jackpot Party Keno

On March 14, 2009, I found a keno variant called Jackpot Party Keno at the Red Rock casino. It's based on the "Jackpot Party" slot machine's bonus round, in which the player keeps selecting prizes before the dreaded "Party Poopers" is selected, which ends the bonus. In traditional keno, the game selects 20 balls at random. Four to seven "Pooper Balls" are added to the hopper in Jackpot Party Keno, and the game continues to select balls until a Pooper Ball is selected. After that, the player is compensated according to the number of hits among the balls drawn before the Pooper Ball.

In contrast to traditional keno, the player selects 2 to 10 numbers from 1 to 40 rather than 1 to 80. The player also determines the number of Pooper Balls in the hopper. The more Pooper Balls there are, the fewer balls are likely to be drawn, and therefore the larger the prizes.

Number of Balls Drawn Before Pooper Ball Probabilities

According to the number of Pooper Balls in the hopper, the following table shows the approximate number of balls drawn before a Pooper Ball.
