A small practice goal

The purpose of your moves
Arrange 1 to 15 in reading order with the empty square at the bottom right. Keep that objective in view throughout the round. Follow this game’s rules rather than another version’s.
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.
Keyboard and screen controls
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.
One way to understand the rules
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.
A common point of confusion
A distant tile cannot jump across other tiles. Read the feedback to see why an action did not have the expected result. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
