I haven't played Keno before but I have always known that there is a lot of similarity to the lottery. In fact, other people like to refer to it as 'Keno lottery.' The similarity has to be in the way random numbers are picked and bet on, in the hope that they'll be drawn out and result in a win.I thought it was similar to the lottery, too. I've never actually played the game but I remember reading an article about how Keno draws are conducted and it seemed to me that they were very similar to lottery draws.
