Patent ID: 8506384

Claim:
An apparatus for controlling a bingo paytable percentage, comprising: a network interface; and a logic system comprising at least one logic device, the logic system configured to do the following: determine a first bingo paytable percentage for a theoretical first bingo game involving a selection of N bingo numbers; determine a second bingo paytable percentage for a theoretical second bingo game involving a selection of N+1 bingo numbers; obtain a desired third bingo paytable percentage for an active bingo game involving a selection of N bingo numbers and a potential award of a free (N+1) th bingo number to a player in the bingo third game, the desired third bingo paytable percentage higher than the first bingo paytable percentage; determine a probability of awarding the free (N+1) th bingo number to the player in the active bingo game, the probability determined, at least in part, by dividing a first difference by a second difference, the first difference calculated by subtracting the first bingo paytable percentage from the desired third bingo paytable percentage, and the second difference calculated by subtracting the first paytable percentage from the second paytable percentage; and provide an indication of the probability.
