Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Notice the feedback after each input.
What you need to achieve

- Finish the ordered board, or choose New puzzle.
Choosing and moving on screen
Use the on-screen controls with a mouse or touch. Read a button’s label before selecting it. A new-round button replaces the current round.
See how the rules apply
When the gap is in the last square, only the tile above it and the tile to its left can move into it. Use the example as a guide rather than a substitute for reading your board. Notice the change in the playing area.
Keep this in mind
A distant tile cannot jump across other tiles. Compare the situation with the worked example. Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules.
