The original 4x4 sliding puzzle brought to you by a bored Cyrek. Click scramble to jumble up the numbers, click a square next to the hole to move it into the hole. The aim is to get all the squares in number order with the hole in the bottom right. i.e. Exactly how it is when the page loads in fact.
If you have a modern browser, you might like to try the Sliding Squares Ultra game which will allow you to choose the dimensions of the grid!
If you get stuck and want to start over, click the Reset button. You can hit scramble again for a new puzzle to solve.
NB: 'Scramble' takes the grid as-is to jumble; it doesn't reset into order first. This means that scrambling more than once may result in a more difficult puzzle.
