Understand the basics of 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. Choose a clear next step rather than rushing through the instructions. Compare the starting position with the example in the Guide. Use the example below to understand a decision.
One thing to notice as you play
Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round. Use the example to check your reasoning.
Your objective
Arrange 1 to 15 in reading order with the empty square at the bottom right. Read that aim before choosing your first action. Return to the instructions when a step is unclear.
How a round unfolds
- 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.
How your actions work
Use the on-screen controls with a mouse or touch. Use the control method described here for this activity. Read the example below alongside these instructions.
Follow the example
When the gap is in the last square, only the tile above it and the tile to its left can move into it. Compare this with the rule that governs the move. Keep the game’s format in mind.
Avoid this misunderstanding
A distant tile cannot jump across other tiles. Check the rule before repeating the action. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
