There's a giant gap between me and my girlfriend's habits: I like long, complicated games where you can fiddle with things, whereas my girlfriend automatically hands her phone to me when there's more than 2 buttons on the screen. So therefore I'm looking for some free (or cheap) games that are simple and straight to the point. But they have to be games, not Solitaire or Threes. Cut the Rope and Angry Birds are the only games I can think of. Any other suggestions?
