How to play Futoshiki
Try Futoshiki at your own pace and keep its objective in view. Place 1–4 once in each row and column while obeying every inequality. Look at what changes after your first action. Read the objective before making your first input. Keep the game area visible while you use its controls.
Twelve 4×4 puzzles with fixed starter values.
Try a deliberate move
After a move, check what changed. Decide which rule explains the new state before acting again. 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. Try to explain the aim in your own words.
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. Use the example as a guide rather than a substitute for reading your board. Take a moment to compare.
Watch out for this
An inequality specifies order, not an exact difference. Read the feedback to see why an action did not have the expected result. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
