Your guide to Futoshiki

Bring this focus to a round

Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round. Make the next step deliberately.

Your objective

Place 1–4 once in each row and column while obeying every inequality. The feedback beside the game helps you follow the round. Check the rules when you are unsure.

How to proceed

  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.

Making selections and moves

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. A new-round button replaces the current round.

A useful example

r1c2 < r1c3 means row 1 column 2 is smaller than row 1 column 3. Compare this with the rule that governs the move. Consider the next action carefully.

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.
