Abstract: Methods and software are disclosed for allocating a jackpot award in a keno game. A win value is randomly established between pre-determined limits. Bets on the outcome of the keno game are taken optionally in chronological order. A percentage of each qualified bet is contributed to a jackpot pool. In one embodiment, a qualified bet is selected at random when the contributions cause the pool to equal or exceed the win value. The owner of the selected bet is allocated the win value. In the alternative, a bet whose contribution causes the accumulating pool to equal or exceed the win value results in the owner of the bet to be allocated the win value, regardless of the outcome of the keno game.
