How to play 15 Puzzle
Read the aim of 15 Puzzle, then make your first move. Arrange 1 to 15 in reading order with the empty square at the bottom right. Check the relevant rule before repeating a move. Read the objective before making your first input. Look at what changes after your first action.
A useful comparison
Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Use the example to check your reasoning.
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. Check any mode label before starting.
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. 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. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
