A useful 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. Consider the next action carefully.
Watch out for this
A distant tile cannot jump across other tiles. Read the feedback to see why an action did not have the expected result. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
