The order of play
- Select an editable square.
- Read inequalities by their row/column coordinates below the board.
- Enter 1–4.

A useful example
r1c2 < r1c3 means row 1 column 2 is smaller than row 1 column 3. Your next round may have a different position, so inspect it before acting. Consider the next action carefully.
Watch out for this
