Your goal
Arrange 1 to 15 in reading order with the empty square at the bottom right. Use the instructions to see which actions move you towards it. Keep the controls in easy reach.
The order of play
- Select a tile directly beside the empty square.
- The tile slides into the gap; diagonal moves are not allowed.
- Use Undo to step back one move.

How to use the controls

See the idea in action
When the gap is in the last square, only the tile above it and the tile to its left can move into it. Use the example as a guide rather than a substitute for reading your board. Keep the controls nearby.
Check this before moving on
A distant tile cannot jump across other tiles. Check the rule before repeating the action. After a move, check what changed. Decide which rule explains the new state before acting again.
