15 Puzzle: rules and examples
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. Check the relevant rule before repeating a move. Choose a comfortable screen position before beginning. Choose a clear next step rather than rushing through the instructions.
Try a more deliberate round
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.
The objective of a round
Arrange 1 to 15 in reading order with the empty square at the bottom right. Read that aim before choosing your first action. Notice how the game responds to your input.
The playing sequence
- 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.
Making selections and moves
Use the on-screen controls with a mouse or touch. Read a button’s label before selecting it. Return to the rules if the result is unexpected.
Learn from a sample situation
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. Read the matching step again.
Keep this in mind
A distant tile cannot jump across other tiles. Read the feedback to see why an action did not have the expected result. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
