How to Start

Click or tap on one of the arrow keys to move the white tiles one step in that direction. The aim is to move the tiles so that they sit over the squares outlined in black in the target number of moves. There are five puzzles increasing in difficulty. Click or tap ‘New Puzzle’ to cycle through the puzzles.

As a last resort, if you really do give in, the Solve button shows you the solution. There is a pause before the tiles begin to move. The targets for the puzzles are shown below.
