How to play 15 Puzzle
Choose a round of 15 Puzzle and settle into its rules. Arrange 1 to 15 in reading order with the empty square at the bottom right. Choose a clear next step rather than rushing through the instructions. Use the opening round to become familiar with the layout. Use the example below to understand a decision.
Make the controls familiar
Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart. Notice the feedback after each input.
Your goal
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. Start with a deliberate move.
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. Use the control method described here for this activity. A new-round button replaces the current round.
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. Compare this with the rule that governs the move. Consider the next action carefully.
Watch out for this
A distant tile cannot jump across other tiles. Take a moment to reassess the position before continuing. When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round.
