You can tell because to solve them it requires a lot of brute forcing and a lot of the clues within a puzzle are redundant. There's a "fill" button that makes it easier to brute force the puzzles, but it doesn't take into account the squares you've already filled so it's next to useless. **Developer response:** The "Fill" button does not take into account cells that the player has filled in himself, because he may make a mistake. Only those cells whose values are known exactly are taken into account. ## Frequently asked questions about Futoshiki ### What is Futoshiki?
