Twelve 4×4 puzzles with fixed starter values.
Practice beyond the first move
After a move, check what changed. Decide which rule explains the new state before acting again. Use the example to check your reasoning.
Your goal
Place 1–4 once in each row and column while obeying every inequality. Keep that objective in view throughout the round. Start with a deliberate move.
Start here and follow along
- 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.
Making selections and moves
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. Read the example below alongside these instructions.
An example to follow
r1c2 < r1c3 means row 1 column 2 is smaller than row 1 column 3. Compare this with the rule that governs the move. Check the stated objective.
Pay attention to this rule
An inequality specifies order, not an exact difference. Read the feedback to see why an action did not have the expected result. Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round.
