The more numbers you mark (different casinos have different limits, 1-20 or 1-15); the bigger is your bet.

Each selected number is matched with respected ball located in the box. All balls are shuffled. Then 20 of them are taken via special transparent tube.

Probability of Winning a Keno Game

How to win at keno 80 numbers? Mathematician and lottery fan Alan Krigman tried to find the answer. He has made some serious researches of keno. He was curious if there is the strategy to win keno games. Classic 20 80 keno lottery gives the house huge advantage (house edge is 65%-75%). Krigman has managed to calculate keno odds and develop the optimal strategy. Probability of winning directly depends on how many numbers were chosen. In other words, how many bets were placed by a player. If a player makes just one bet his odds are 25%. In case of 2 bets odds go up to 38% (6% of winning both bets). If a player makes 3 bets, he will have 43.1% odds of winning (1.4% of winning 1 bet and 13.9% of 2 bets) and so on. It is almost impossible to describe all keno number combinations.
