Keno is purely a game of chance and luck. Honestly, no strategy will bring you guaranteed winnings. This game is more geared towards its entertainment value and the ease of playing it.

When in a casino, you will even see players playing the same numbers as the person next to them. Before you sit down to play always consider the odds below.

The probability of catching exactly R spots when you bet on N of them (where N >= R) is given by

P(N,R) = c(N,R) * c(80-N, 20-R) / c(80,20)

where c(N,R) is the famous "binomial coefficient" and c(N,R) = f(N,R) / f(R,R)

f(N,0) = 1, otherwise f(N,R) = N * f(N-1,R-1)


Now you know that anyone that tries to offer a good strategy is nothing but a sales person.
