How to play Futoshiki
Futoshiki gives you a focused activity to play in your browser. Place 1–4 once in each row and column while obeying every inequality. Choose a clear next step rather than rushing through the instructions. Keep the instructions close while learning this activity. Look at what changes after your first action.
Twelve 4×4 puzzles with fixed starter values.
Keep the aim in sight
Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules. Notice the feedback after each input.
Your goal
Place 1–4 once in each row and column while obeying every inequality. An attractive position is not enough unless the goal is met. Try to explain the aim in your own words.
Step by step
- 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.
Controls
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. Use the control method described here for this activity. Use one clear input at a time.
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. Keep the controls nearby.
Watch out for this
An inequality specifies order, not an exact difference. Read the feedback to see why an action did not have the expected result. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
