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. Check the rules when you are unsure.
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. Read a button’s label before selecting it. Return to the rules if the result is unexpected.
A useful example
r1c2 < r1c3 means row 1 column 2 is smaller than row 1 column 3. Compare this with the rule that governs the move. Keep the game’s format in mind.
Watch out for this
An inequality specifies order, not an exact difference. A different version of the game may use a different rule. When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round.
