Car Jam

Car Jam is the classic sliding traffic puzzle, set in a sunny little car park seen from above. Six bays by six are packed with chunky cartoon cars, taxis, pickups, buses, box trucks and tankers, and one red car that needs to get out. Every vehicle slides only along its own lane, forwards or backwards, never sideways, so the job is to work out who has to move, and in which order, to open a path to the exit on the right. Drag the red car through the gap, the barrier lifts and off it drives.

There are sixty car parks across three floors, sorted from a quick four-move warm-up to thirty-two-move jams that will properly test your brain. Each one was generated from a seed and proven by a solver, so par is always the true shortest solution: finish in par for three stars, within three moves of it for two, and any finish earns one. Undo and redo as often as you like, and if you are stuck, the hint slides a ghost of the next best move into place.

The Daily car park is the same for everyone on the same day, gentle on Monday and a proper jam by Sunday, and solving it keeps your daily streak going. There is no clock, so you can relax and take your time, or race yourself for fewer moves. Drag with a mouse or a finger, or pick a car with the arrow keys and slide it with Shift and the arrows. Your stars, best move counts and streak are saved on your device.
