See the idea in action
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.
Pay attention to this rule
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.
