I think this app is great but I do feel that the coin system is unbalanced. A few reviews have already raised this issue and I believe either removing the coins for online play, or winning a certain amount, would give more people an incentive to keep playing. Using 500 coins with nothing to show for it after does not make me want to play for multiple rounds at a time. Moreover, the coins you win if you place 2nd in online play is pitiful considering it's 1000 to enter.
