Game mechanics are good, but the coin mechanics are horrible. If you play online and lose the 1st game, that's it--can't play again for 2 hours until your coins recharge. And they don't recharge incrementally, you have to wait until each full hour has passed to be able to get them. Play offline & you can't win coins at all. So win or lose, you can only play a few games before coins are gone. "Adventure" mode is essentially a golf solitaire game where you can maybe win a few coins but not enough.
