THE PLAYBOOK · SUDAANMO
Understand the basics of 15 Puzzle
Open 15 Puzzle, check the instructions and begin a round. 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. Choose a comfortable screen position before beginning. Look at what changes after your first action.
Try a more deliberate round
Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Use the example to check your reasoning.
Aim for this result
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.
From the start of a round
- 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 to use the controls
Use the on-screen controls with a mouse or touch. On a smaller screen, keep the active part of the board within view. Return to the rules if the result is unexpected.
Work through an example
When the gap is in the last square, only the tile above it and the tile to its left can move into it. Focus on why the action is allowed, not only its outcome. Verify the rule before continuing.
A useful caution
A distant tile cannot jump across other tiles. Take a moment to reassess the position before continuing. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
