Your goal is to reposition the tiles in ascending order from 1 (the top left corner) to 15 counting left to right. The hole has to be in the bottom right corner.

You can move the tiles in the following ways:

  • using the arrow keys. This moves just one tile
  • using WASD. That moves the whole row/column
  • by clicking/tapping an appropriate tile

To get back to the game use «ESC» and to reset the game use «SPACE»

Good luck! The clock is ticking!
