Are you up for a challenge?

This is a greatly enjoyable classic puzzle game in which you need to sort the numbers in ascending order, starting from a random configuration. You could probably solve a basic 3x3 board in less than 30 seconds, with some luck. But the difficulty increases as you move up to larger boards.


How to play:

You can only move one tile at a time, by clicking on it. (Warning: don't try to drag the tile, it won't work. Just click on it and it will then move). There is a gap in the board and you can only move a tile that borders on that gap. Some configurations, you may suspect they're impossible to solve, but I assure you, there's always a solution!


Let the fun begin!
