One thing to notice as you play
When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round. Use the example to check your reasoning.
The challenge in front of you
Arrange 1 to 15 in reading order with the empty square at the bottom right. The feedback beside the game helps you follow the round. Notice how the game responds to your input.
The playing sequence
- 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.
Making selections and moves
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. Your next round may have a different position, so inspect it before acting. Verify the rule before continuing.
Keep this in mind
A distant tile cannot jump across other tiles. Read the feedback to see why an action did not have the expected result. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
