15 Puzzle: a guide for your next round
Bring your attention to one round of 15 Puzzle. 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. Check the rule that explains your first action. Check the relevant rule before repeating a move.
An idea for your next attempt
After a move, check what changed. Decide which rule explains the new state before acting again. Notice the feedback after each input.
The goal to keep in mind
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. Keep the controls in easy reach.
The steps to play
- 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.
Choosing and moving on screen
Use the on-screen controls with a mouse or touch. On a smaller screen, keep the active part of the board within view. Contact us with the game and device if a control does not respond.
A closer look at one 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. Notice the change in the playing area.
A common point of confusion
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.
