In most versions of Keno the player does not have the ability to make any decisions other than the original numbers to bet on. Because all numbers have an equal probability of comming up, Keno is largly a game of chance, rather than skill. Bonus Keno gives the player a little more choice after the game has begun. As in traditional video keno, the player chooses up to 15 numbers, and the computer follows that up with choosing 20 numbers. The more numbers the player matches, the higher his payout. In Bonus Keno, after the original numbers are played, the player has the choice of ending the game, or doubling his bet for an additional 3 numbers chosen by the computer. A player that is one ball from a large payout can choose to play those additional 3 numbers to see if he can get the large payout.
