Actions

Lot size

A bigger lot is a different puzzle, not just a longer one — more vehicles to read and far more ways to go wrong. Changing the size deals a new board.

Difficulty

Graded by the shortest solution that exists. Every board is verified solvable before you see it.

Coach

Show how far from solved I am Reveals the exact distance to the exit after every move, and grades each move against the solver. Great for learning, but it does a lot of the thinking for you.

Moves

Personal bests 6×6

Recorded per lot size, and only for solves without hints.

How it works

Each vehicle slides only along its own axis — a car facing across the lot never turns.
Nothing jumps over anything. A vehicle stops at the first thing in its way.
Sliding one vehicle any distance counts as one move.
Drive the red car out through the gap in the right-hand wall.
