Your goal
Place 1–4 once in each row and column while obeying every inequality. Keep that objective in view throughout the round. The example below illustrates a decision.
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.
Controls
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. Keep the playing area visible while using these controls. Contact us with the game and device if a control does not respond.
A useful example
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. Keep the controls nearby.
Watch out for this
An inequality specifies order, not an exact difference. Check the rule before repeating the action. Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round.
