Controls
Use the on-screen controls with a mouse or touch. Read a button’s label before selecting it. Read the example below alongside these instructions.
Work through an 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. Keep the game’s format in mind.
Keep this in mind
A distant tile cannot jump across other tiles. Take a moment to reassess the position before continuing. After a move, check what changed. Decide which rule explains the new state before acting again.
