A practical guide to Futoshiki
Use a short break to learn the rhythm of Futoshiki. Place 1–4 once in each row and column while obeying every inequality. Look at what changes after your first action. Treat the first round as a chance to learn the controls. Use the example below to understand a decision.
Twelve 4×4 puzzles with fixed starter values.
Bring this focus to a round
After a move, check what changed. Decide which rule explains the new state before acting again. Make the next step deliberately.
What counts as success
Place 1–4 once in each row and column while obeying every inequality. Read that aim before choosing your first action. Notice how the game responds to your input.
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.
Input guidance
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 one clear input at a time.
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.
Avoid this misunderstanding
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.
