Bring this focus to a round
Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow. Notice the feedback after each input.
What you are aiming for
Arrange 1 to 15 in reading order with the empty square at the bottom right. The feedback beside the game helps you follow the round. Check the rules when you are unsure.
From the start of a round
- 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.
- Finish the ordered board, or choose New puzzle.
Using the playing area
Use the on-screen controls with a mouse or touch. Keep the playing area visible while using these controls. Look at the feedback after the action.
A useful example
When the gap is in the last square, only the tile above it and the tile to its left can move into it. Focus on why the action is allowed, not only its outcome. Choose a deliberate next step.
Watch out for this
A distant tile cannot jump across other tiles. Compare the situation with the worked example. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
