Read before your next round of 15 Puzzle
Bring your attention to one round of 15 Puzzle. 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. Keep the game area visible while you use its controls.
A small practice goal
After a move, check what changed. Decide which rule explains the new state before acting again. Use the example to check your reasoning.
The purpose of your moves
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. Notice how the game responds to your input.
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.
The controls to know
Use the on-screen controls with a mouse or touch. Use the control method described here for this activity. Look at the feedback after the action.
Follow the 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.
One detail worth checking
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.
