There are a variety of strategies for playing KENO. None of them provide you with any advantage, but they can be fun to play. Some of them can also be mighty expensive.
As with roulette you can "chase the old man", meaning play those numbers that seem to be coming up more often than the others. The theory is that they will keep coming up again in the future. The reality is they don't come up any more than chance dictates. Or you can "let the old man chase you", meaning play numbers that haven't come up in recent games, on the theory that they'll start coming up in order to make the long-run results for each number even out. Again, the reality is that the balls have no memory. Number 47 may not have come up in the last 10 games, but that has no predictive value. In such a case the molecules that make up ball number 47 do not strain themselves to "even the score".
The KENO playing card is divided into an upper and lower half. My uncle Dave would always be sure to spread his picks evenly across both halves in order to "play the whole card". His theory was that if you just picked 6 numbers from say the lower half then you wouldn't catch as many as if you picked 3 numbers from the lower half and 3 from the upper half. After all, most every game will see about half the house numbers drawn in the upper part and half drawn in the lower part. But the reality is that it doesn't matter, the balls don't care what the playing cards look like. The house could print every card differently. A set of numbers that produces a balanced card for one configuration might be highly unbalanced in another. This will not cause one set of numbers to be drawn more often than any other set.
While not exactly a strategy, some players may find it entertaining to play somebody else's losing ticket. If the guy next to you gets up to leave, take his losing ticket to the dealer and say "Play it again". This takes a certain amount of timing, judgement and chutzpah (a by-product of several Rumple Minze's on the house), but can be fun if pulled off well.
KEN0 Gambling is the game of choice for me. Cheap and easy to play and gives me the most excitment, UK.
