Take a closer look while playing
Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart. Refer to the controls when needed.
What you are aiming for
Place 1–4 once in each row and column while obeying every inequality. Keep that objective in view throughout the round. Keep the controls in easy reach.
The playing sequence
- 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.
Keyboard and screen 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.
Work through an example
r1c2 < r1c3 means row 1 column 2 is smaller than row 1 column 3. Your next round may have a different position, so inspect it before acting. 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. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
