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. Keep the game area visible while you use its controls. Identify the playing area and the controls you need. Look at what changes after your first action.
Twelve 4×4 puzzles with fixed starter values.
A small practice goal
Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow. Notice the feedback after each input.
Your goal
Place 1–4 once in each row and column while obeying every inequality. Read that aim before choosing your first action. Start with a deliberate move.
Work through the instructions
- 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.
Getting comfortable with the controls
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. A careful first action helps you become familiar with the layout. Check any mode label before starting.
Put the rules into context
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.
A useful caution
An inequality specifies order, not an exact difference. A different version of the game may use a different rule. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
