Slide the cars out of the way to clear a path for the coral car.

Click a car to select it, then click an empty cell in the direction you want to move — it slides as far as it can go. Get the coral car all the way to the exit on the right.

The strategy the target car hides from you

This is a version of the classic sliding-block logic puzzle that a physical toy popularized worldwide in the 1990s — every car only slides along its own single axis, which sounds simple until three or four cars are all blocking each other's only way to move.

The move that trips people up: pushing the target car forward as far as it'll go, then getting stuck. Work backward from the exit instead — find the car actually sitting in the target's path, then figure out which direction *that* car needs to clear before you touch the target at all. Often the real first move is a car that looks unrelated to the exit.

Computer scientists have studied puzzles in this exact family as a genuinely hard planning problem, not just a kids' toy — the number of possible board states grows fast enough that even a computer benefits from a real search strategy rather than trying moves at random. Every puzzle here is generated and verified solvable the same way, by actually searching for a path to the exit before it's ever shown to you.

Common questions

How do I move a car?

Click a car to select it, then click an empty cell in the direction you want it to go — it slides as far as it can that way.

Which car am I trying to move?

The coral car on the marked row — get it all the way to the right edge to solve the puzzle.

What do the difficulty levels change?

Easy uses a smaller, less crowded board that usually solves in one or two moves. Medium and Hard add more cars — Hard also uses a slightly bigger board — so clearing a path takes real planning.
