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. Treat the first round as a chance to learn the controls. Choose a clear next step rather than rushing through the instructions.
Focus on one rule
Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow. Use the example to check your reasoning.
Your goal
Arrange 1 to 15 in reading order with the empty square at the bottom right. Read that aim before choosing your first action. The example below illustrates a decision.
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. On a smaller screen, keep the active part of the board within view. Use the visible help when you are unsure of the next input.
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. Verify the rule before continuing.
Watch out for this
A distant tile cannot jump across other tiles. Compare the situation with the worked example. After a move, check what changed. Decide which rule explains the new state before acting again.
