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. Use the example below to understand a decision. Choose a comfortable screen position before beginning. Choose a clear next step rather than rushing through the instructions.
Keep the aim in sight
Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules. 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. 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. Use the control method described here for this activity. Look at the feedback after the action.
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. A different version of the game may use a different rule. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
