Brain Jam

Brain Jam is a sliding car puzzle with one twist: it counts the calories your brain burns while you think. The parking lot is jammed. Slide the cars out of the way and drive the red one to the exit. Every second you spend thinking feeds a live calorie counter, and the longer you concentrate without moving a car, the faster it climbs. 120 hand-checked levels, plus a Daily Puzzle that is the same for every player in the world, so you can compare your result with friends.
