Keno Odds Wherever you choose to play the payout schedule overall is geared to provide around a 70% return for live Keno and around 85-90% for Online and Video Keno. This doesn't sem like a big difference but think of it in the inverse terms - the casino's profit. A game that gives you a 95% return means the casino is keeping 5% but a game that is giving you a 70% return then the casino is keeping 30% - 6 times as much! You can download my Keno Odds spreadsheet by right-clicking KenoOdds.xls and selecting "Save target as" to figure out what the casino edge is in your keno game.The equation for calculating the probability (p) of hitting (n) numbers out of the (x) numbers you picked when (y) numbers were drawn out of (z). (i.e. - "What is the probability of hitting 4 out of the 5 numbers I picked when 20 numbers were drawn out of 80"). n = 4 x = 5 y = 20 z = 80 p(x,n) = (combin(x,n) * combin(z-x,y-x+n)) / combin(z,y) It is important not to look at the payout schedules but to actually see how much profit the casino is keep from the money you wager. That's what the following does. I took 2 payout schedules and calculated the casino edge on all the bets and showed it in red. At first glance the 2nd payout schedule looks better because the high-end payouts are much higher but payouts are smaller on the lower end. But the payouts on the small end occur much more frequently and that's where the value of the ticket is most of the time. The 1st payout schedule shows a casino edge of about 7% while the 2nd schedule shows an edge anywhere 21-66%! You will lose your money anywhere from 3-9 times as fast playing the 2nd schedule if you choose to play the game with the big payoffs. Odds based on the standard 80 ball game, 20 balls drawn.
