Understand the basics of Futoshiki

Build familiarity through play

Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow. Make the next step deliberately.

The challenge in front of you

Place 1–4 once in each row and column while obeying every inequality. Read that aim before choosing your first action. Try to explain the aim in your own words.

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.

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. Avoid pressing the same control repeatedly while a move is being processed.

An example to follow

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. Keep the game’s format in mind.

A mistake to avoid

An inequality specifies order, not an exact difference. Compare the situation with the worked example. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
