Use the on-screen controls with a mouse or touch. Read a button’s label before selecting it. Use one clear input at a time.
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. Use the example as a guide rather than a substitute for reading your board. Keep the controls nearby.
Check this before moving on
A distant tile cannot jump across other tiles. Compare the situation with the worked example. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
