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. Compare this with the rule that governs the move. Choose a deliberate next step.
Pay attention to this rule
A distant tile cannot jump across other tiles. Read the feedback to see why an action did not have the expected result. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
