Gimme Friction Baby is a great game with some serious addiction potential. A review describes it this way:
There is a certain paradigm shift that must occur when playing this game for the first time before the light goes on and the player ‘gets it’. I believe this is due to a sort of cognitive bias we have as gamers: when firing a turret we expect things to explode… and to go fast.
Simplicity and complexity. This game finds it’s fun in being the opposite of what you’d expect from a traditional turret game. There is a version made for the iphone and a spinning version called Gimme Rotation if you’re looking for something with a little more challenge and a little faster paced.
My high score after about 20 minutes: 12.
