How to play 15 Puzzle
15 Puzzle gives you a focused activity to play in your browser. Arrange 1 to 15 in reading order with the empty square at the bottom right. Keep the game area visible while you use its controls. Use the opening round to become familiar with the layout. Check the relevant rule before repeating a move.
Notice the feedback
Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Make the next step deliberately.
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. Keep the controls in easy reach.
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. Apply the same reasoning to the position in your own round. Verify the rule before continuing.
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. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
