One thing to notice as you play
Read one step at a time and try it on the playing area. Match the instruction to the control you use. Make the next step deliberately.
Your goal
Place 1–4 once in each row and column while obeying every inequality. An attractive position is not enough unless the goal is met. Check the rules when you are unsure.
The order of play
- 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.

Check this before moving on
