Futoshiki RULES. 1. Complete the grid such that every row and column contains the numbers 1 to 4. 2. The arrows on the grid are less-than and greater-than signs. Example: 1 < 4, 2 < 3, 2 < 4. It's a fun Sudoku like alternative. Personally, I love these Japanese Puzzle Games. They are simple, and a good way to pass a few minutes. Basically, this is Sudoku with the added challenge of following the less than and greater than symbols. But the grid is not as large, so it isn't quite as hard. ## Key features - Number placement in rows and columns - Inequality symbol constraints - Sudoku-like gameplay - Grid-based puzzles - Quick mental challenges ## Recent user reviews (5 of 5) All indexed reviews: https://appshunter.io/ios/app/futoshiki-sudoku-like-japanese-puzzle-game/id1135031772/reviews.md ### 2/5 — Disappointing *2022-08-11, version 1.0* I agree with Richbrad. Too many possible answers. Not enough effort being made to check the quizzes. Very disappointing Like others have said, it’s total crap. ### 2/5 — Good start, needs updating *2018-05-23, version 1.0* It’s a good app, but there are too many times when there is more than one solution to the puzzle. I often complete it, with every element correct, & yet it is not the solution they were looking for, so I can’t move on to the next ### 3/5 — Needs undo option *2018-02-10* Without undo button this game is quite limited. ### 2/5 — A good start but needs upgrade *2017-11-07, version 1.0* Best thing - it’s free and there are no in-app purchase offers. It presents prepared puzzles, but entering the numbers is a bit clunky (press the box 4 times to enter 4). There is no way to select the level of difficulty (eg, easy, moderate, difficult). It would be good to be able to set up your own puzzle (eg, copied from a newspaper) for those puzzles you were not able to solve first time. ### 2/5 — Others do it better *2017-04-16, version 1.0* This is very similar to another Futoshiki game, except the other one permits the annotations that are essential to solving the puzzles. ## Frequently asked questions about Futoshiki (Sudoku like Japanese Puzzle Game) ### What are the rules of Futoshiki?
