Understand the basics of Futoshiki

A focus for your next round

Read one step at a time and try it on the playing area. Match the instruction to the control you use. Use the example to check your reasoning.

Aim for this result

Place 1–4 once in each row and column while obeying every inequality. The feedback beside the game helps you follow the round. Follow this game’s rules rather than another version’s.

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.

Keyboard and screen 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. Contact us with the game and device if a control does not respond.

Try this example

r1c2 < r1c3 means row 1 column 2 is smaller than row 1 column 3. Apply the same reasoning to the position in your own round. Consider the next action carefully.

A common point of confusion

An inequality specifies order, not an exact difference. A different version of the game may use a different rule. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
