NRICH: Sliding Puzzle

The aim of the game is to slide the green square from the top right hand corner to the bottom left hand corner in the least number of moves.

Age 11 to 16

This puzzle is an old favourite. The aim of the game is to slide the green square from its starting position, in the top right hand corner, to the bottom left hand corner in the least number of moves. You may only slide squares up, down, left or right and not diagonally.

Try first on a small two by two grid and then as you become more confident, alter the size.

Can you find a strategy?
