Your guide to Futoshiki

Make Futoshiki your next activity in the game library. Place 1–4 once in each row and column while obeying every inequality. Choose a clear next step rather than rushing through the instructions. Use the opening round to become familiar with the layout. Look at what changes after your first action.

Twelve 4×4 puzzles with fixed starter values.

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. Make the next step deliberately.

Understand the aim

Place 1–4 once in each row and column while obeying every inequality. An attractive position is not enough unless the goal is met. Follow this game’s rules rather than another version’s.

Follow these playing steps

  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.

Controls

Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. On a smaller screen, keep the active part of the board within view. Use the visible help when you are unsure of the next input.

An example before you play

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. Verify the rule before continuing.

Pay attention to this rule

An inequality specifies order, not an exact difference. Read the feedback to see why an action did not have the expected result. When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round.
