A closer look at one example
When the gap is in the last square, only the tile above it and the tile to its left can move into it. Focus on why the action is allowed, not only its outcome. Notice the change in the playing area.
A common point of confusion
A distant tile cannot jump across other tiles. Check the rule before repeating the action. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
