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. Choose a deliberate next step.
A mistake to avoid
A distant tile cannot jump across other tiles. A different version of the game may use a different rule. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
