Step by step
- Select an editable square.
- Read inequalities by their row/column coordinates below the board.
- Enter 1–4.

Controls
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. Use the control method described here for this activity. Look at the feedback after the action.
A useful example
r1c2 < r1c3 means row 1 column 2 is smaller than row 1 column 3. Focus on why the action is allowed, not only its outcome. Keep the controls nearby.
Watch out for this
An inequality specifies order, not an exact difference. A different version of the game may use a different rule. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
