Frequently asked questions
- How is futoshiki played?
- Each row and column holds the numbers 1 to the size of the grid once, as in sudoku without boxes. A sign between two squares says which is greater: in 3 > □ the empty square can only be 1 or 2.
- Where do I start?
- At the ends of chains of signs: a square smaller than another cannot hold the largest number, and one at the bottom of a chain of three signs in a 5 × 5 can be at most 2.
- Does each puzzle have only one answer?
- Yes. Every puzzle is solved before it is printed and has exactly one answer; clues are taken away only while the rest still lead to it by logic, without guessing.
- What does futoshiki mean?
- It is Japanese for “inequality”; the puzzle is also sold as unequal or inequality puzzles.
- Is there a footer on it?
- Only on the free plan: a small line “Made with nouplo.com” at the foot of the last page. With Pro there is none. Either way the sheet is made in your browser.
