Futoshiki: from controls to your first round
Read the aim of Futoshiki, then make your first move. Place 1–4 once in each row and column while obeying every inequality. Look at what changes after your first action. Treat the first round as a chance to learn the controls. Check the relevant rule before repeating a move.
Twelve 4×4 puzzles with fixed starter values.
Practice beyond the first move
Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Notice the feedback after each input.
What counts as success
Place 1–4 once in each row and column while obeying every inequality. Use the instructions to see which actions move you towards it. Notice how the game responds to your input.
How a round unfolds
- Select an editable square.
- Read inequalities by their row/column coordinates below the board.
- Enter 1–4.
- Check puzzle verifies both Latin-square rules and inequalities.
How your actions work
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. Avoid pressing the same control repeatedly while a move is being processed.
See the idea in action
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.
Avoid this misunderstanding
An inequality specifies order, not an exact difference. Read the feedback to see why an action did not have the expected result. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
