Just like smurfs or other similar games, you need to be patient or buy cash. But it's fairly addicting.

Had this game for a while now, but didn't like much because it lagged quite a bit. Now that I have the iPad 2, this game is flawless. No lags, graphics aren't choppy, and controls are now responsive. So my advice, get this game only if you have an iPad 2.

Great

Never tiring
