Futoshiki: rules and examples

Bring your attention to one round of Futoshiki. Place 1–4 once in each row and column while obeying every inequality. Choose a clear next step rather than rushing through the instructions. Treat the first round as a chance to learn the controls. Keep the game area visible while you use its controls.

Twelve 4×4 puzzles with fixed starter values.

Try a more deliberate round

Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Refer to the controls when needed.

The objective of a round

Place 1–4 once in each row and column while obeying every inequality. Read that aim before choosing your first action. Return to the instructions when a step is unclear.

Work through the instructions

  1. Select an editable square.
  2. Read inequalities by their row/column coordinates below the board.
  3. Enter 1–4.
  4. Check puzzle verifies both Latin-square rules and inequalities.

Your inputs

Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. Keep the playing area visible while using these controls. A new-round button replaces the current round.

Work through an 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. Check the stated objective.

Where a round can go wrong

An inequality specifies order, not an exact difference. Take a moment to reassess the position before continuing. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
