Step by step
- Select an editable square.
- Read inequalities by their row/column coordinates below the board.
- Enter 1–4.
- Check puzzle verifies both Latin-square rules and inequalities.
The controls to know
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. Use one clear input at a time.
An example to follow
r1c2 < r1c3 means row 1 column 2 is smaller than row 1 column 3. Apply the same reasoning to the position in your own round. Read the matching step again.
An important reminder
An inequality specifies order, not an exact difference. Check the rule before repeating the action. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
