Learn the rules of 15 Puzzle
Start 15 Puzzle by looking at the playing area and its controls. 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. Identify the playing area and the controls you need. Use the example below to understand a decision.
A small practice goal
Before your first action, say what you are trying to achieve. Then compare the result with the goal. Use the example to check your reasoning.
Your objective
Arrange 1 to 15 in reading order with the empty square at the bottom right. Keep that objective in view throughout the round. Start with a deliberate move.
How to proceed
- 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.
Using the playing area
Use the on-screen controls with a mouse or touch. Keep the playing area visible while using these controls. Use one clear input at a time.
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. 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. Compare the situation with the worked example. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
