How to play Futoshiki
Bring your attention to one round of Futoshiki. Place 1–4 once in each row and column while obeying every inequality. Use the example below to understand a decision. Choose a comfortable screen position before beginning. Choose a clear next step rather than rushing through the instructions.
Twelve 4×4 puzzles with fixed starter values.
Focus on one rule
Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow. Refer to the controls when needed.
Your goal
Place 1–4 once in each row and column while obeying every inequality. The feedback beside the game helps you follow the round. Return to the instructions when a step is unclear.
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. A careful first action helps you become familiar with the layout. Use one clear input at a time.
A useful example
r1c2 < r1c3 means row 1 column 2 is smaller than row 1 column 3. Focus on why the action is allowed, not only its outcome. Notice the change in the playing area.
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.
