Keno, like the lottery, is a game of pure luck. If you're familiar with the state lottery, you have enough knowledge already to play keno. But, if you don't know much about either of the two, this is a good place to start. In both cases you select a variety of numbers and hope that those will be picked in a draw. Depending on how many numbers you got right, you might get some kind of payoff, but that depends on what game you play - some may be more generous than others. Whether it's the lottery or keno, neither is a positive expectation game and won't return much of what you put into it, but if you hit the big numbers everything you've ever put into keno will be paid back and more!
