Use the on-screen controls with a mouse or touch. Use the control method described here for this activity. Avoid pressing the same control repeatedly while a move is being processed.
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. Keep the game’s format in mind.
Watch out for this
A distant tile cannot jump across other tiles. Take a moment to reassess the position before continuing. After a move, check what changed. Decide which rule explains the new state before acting again.
