A careful first round
Before your first action, say what you are trying to achieve. Then compare the result with the goal. Keep the objective visible.
Your goal
Place 1–4 once in each row and column while obeying every inequality. Use the instructions to see which actions move you towards it. Review the board or playing area as it changes.
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. Make sure you are interacting with the game rather than the surrounding page.
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. Consider the next action carefully.
Watch out for this
An inequality specifies order, not an exact difference. Compare the situation with the worked example. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
