Use the on-screen controls with a mouse or touch. Keep the playing area visible while using these controls. Avoid pressing the same control repeatedly while a move is being processed.

See how the rules apply

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. Check the stated objective.

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. After a move, check what changed. Decide which rule explains the new state before acting again.
