Rules, controls and help for 15 Puzzle
Make 15 Puzzle your next activity in the game library. 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. Identify the playing area and the controls you need. Look at what changes after your first action.
Practice beyond the first move
After a move, check what changed. Decide which rule explains the new state before acting again. Keep the objective visible.
What the game asks you to do
Arrange 1 to 15 in reading order with the empty square at the bottom right. An attractive position is not enough unless the goal is met. The example below illustrates a decision.
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.
Input guidance
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.
Put the rules into context
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. Keep the controls nearby.
A useful caution
A distant tile cannot jump across other tiles. Read the feedback to see why an action did not have the expected result. 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.
