- Use Undo to step back one move.
- Finish the ordered board, or choose New puzzle.
Keyboard and screen controls
Use the on-screen controls with a mouse or touch. On a smaller screen, keep the active part of the board within view. Make sure you are interacting with the game rather than the surrounding page.
An example to follow
When the gap is in the last square, only the tile above it and the tile to its left can move into it. Compare this with the rule that governs the move. Keep the game’s format in mind.
A common point of confusion
A distant tile cannot jump across other tiles. Take a moment to reassess the position before continuing. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
