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. Apply the same reasoning to the position in your own round. Consider the next action carefully.
Watch out for this
A distant tile cannot jump across other tiles. Compare the situation with the worked example. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
