Get the red car out through the gap on the right. Cars only slide along their own lane — no turning, no lifting.

• Click a car, then click where you want it; any distance counts as one move.
• Par is the fewest moves possible — found by exhaustive search when the jam was built.
• Work backwards: what has to move out of the red car's path, and what blocks that?

Nob Yoshigahara's sliding-block puzzle is a favourite benchmark for search algorithms — and a real workout for planning several moves ahead.
