How to play 15 Puzzle
Take a moment with 15 Puzzle before moving to another game. Arrange 1 to 15 in reading order with the empty square at the bottom right. Look at what changes after your first action. Check the rule that explains your first action. Check the relevant rule before repeating a move.
A careful first round
Before your first action, say what you are trying to achieve. Then compare the result with the goal. Keep the objective visible.
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. Follow this game’s rules rather than another version’s.
Step by step
- 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.
Controls
Use the on-screen controls with a mouse or touch. A careful first action helps you become familiar with the layout. 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. Use the example as a guide rather than a substitute for reading your board. Check the stated objective.
Watch out for this
A distant tile cannot jump across other tiles. Read the feedback to see why an action did not have the expected result. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
