Learn from a sample situation
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. Keep the game’s format in mind.
Pay attention to this rule
A distant tile cannot jump across other tiles. Take a moment to reassess the position before continuing. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
