A useful comparison
Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. 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. 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. Use the control method described here for this activity. Use the visible help when you are unsure of the next input.
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. Verify the rule before continuing.
Watch out for this
An inequality specifies order, not an exact difference. A different version of the game may use a different rule. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
