How to play 15 Puzzle
Try 15 Puzzle at your own pace and keep its objective in view. 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.
A careful first round
Before your first action, say what you are trying to achieve. Then compare the result with the goal. Notice the feedback after each input.
Your goal
Arrange 1 to 15 in reading order with the empty square at the bottom right. Keep that objective in view throughout the round. Check the rules when you are unsure.
Step by step
- 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.
Controls
Use the on-screen controls with a mouse or touch. A careful first action helps you become familiar with the layout. Avoid pressing the same control repeatedly while a move is being processed.
A useful example
When the gap is in the last square, only the tile above it and the tile to its left can move into it. Apply the same reasoning to the position in your own round. Keep the game’s format in mind.
Watch out for this
A distant tile cannot jump across other tiles. Take a moment to reassess the position before continuing. When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round.
