Zen bound 2 One stage can took 30 min, best time killer.... Sometime i need this, as a human not every time i can open my ibook haha..

Another one is The Room

Doors and rooms (or Dungeons and rooms i forget already lol)

Yea...Doors and Rooms is pretty much a very good puzzle

try the room pocket or the room, seriously worth the few hours i got stuck on one puzzle. on ios, i think on android as well cant be sure. they're also going to come with the sequel soon. awesome puzzle game!
