I'd also disagree that skee-ball is a game of chance, because at the least, it's a game where how well you do is determined almost entirely by how well you roll the balls. And it's not a game, like a ring toss game, where you have to get lucky to do well.

I've played skee ball at a couple places where it really is a "pure", fair, game and it's a bunch of fun. I can imagine less ethical places doing the things you've suggested, though I've never seen it myself.
