How to play Futoshiki
Futoshiki on SLTPPF is organised around a clear objective: Place 1–4 once in each row and column while obeying every inequality. Begin with careful restarts and use the playbook beside the game.
Twelve 4×4 puzzles with fixed starter values.
Careful restarts
Start a fresh round when you want another attempt. Restarting may discard current progress; read the controls rather than assuming an account backup exists.
Your goal
Place 1–4 once in each row and column while obeying every inequality.
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.
A useful example
r1c2 < r1c3 means row 1 column 2 is smaller than row 1 column 3.
Watch out for this
An inequality specifies order, not an exact difference.
