You added this as I was making my reply, so I'm sorry for the multiple posts responding:
The only thing I don't get is, how is it worth anyone's time to play anything, when with most typical gambling establishments (dice, blackjack, whatever) the house wins in the long run by definition.
Personally I would much prefer to play on sites where the outcome isn't completely random and I have at least a small chance to play smart, and it's not mathematically predicted that I will be losing in the long run. Sure, maybe I make less per game, but at least I have a chance to stop playing with more money than what I started with.
Entertainment. Leisure time has value. That's why casinos are so large and nice. Because people are willing to lose money in order to have fun, be excited, and have the potential to win big. It's also why beatable games (poker, sportsbetting) are afterthoughts and add nearly nothing to the bottom line.
Also, as I mentioned, the way you bet on your own game drops the equity that any bets by the real players would have, making a bunch -ev.
