Keno odds, payouts and the house edge

Keno Odds

If you take an average of ten numbers picked, you can see that the odds of getting several hits look quite good, but that the chance of achieving ten hits out of ten is extremely slim.

Do the math and you will see that while your odds of getting from one to five hits are fairly good, odds of a perfect match with all ten of the winning numbers are one in a million. What this means in practical terms is that if you enjoy the fun and excitement of betting on Keno, go ahead and enjoy yourself, but don’t count on it as a guaranteed get rich quick scheme.

Keno Payouts

Once again, each casino offering Keno, online or off, may have a somewhat different system of payouts. This will be influenced by the permissible total of numbers players may select. Every casino must display its own pay table, detailing how much each winning combination will pay off. To quickly determine how worthwhile a particular bet may be, find the “O/P” (odds to payout) ratio. This is done by dividing the payout by the odds. An ideal bet is one with an O/P as close to 1 as possible.

Keno House Edge

The house edge in Keno varies according to the casino offering the game, because various casinos have somewhat different versions. They all allow players a certain amount of leeway in choosing how many numbers to pick. However, some casinos permit a minimum of only one number while others require at least four. The maximum ranges from ten numbers in some online casinos up to 20 at many land based venues. Within these broad parameters, though, the average house edge has been calculated to be about 30 percent. This is perhaps the highest house edge for any casino game.
