I've been on the board way too much today- now I'm replying to my own post!!!!!
I guess, to close this thread (decidedly off-topic now ) with one final observation-
The higher the house edge on a given game, the more eager they are to comp you, and that figures in to the marketing computer's decison as well. In lieu of Keno, you could just make hop bets at the craps table all day...16% against.
And so it goes.
