## What is The Futoshiki?

What is Futoshiki?

Futoshiki is a funny logic puzzle game from Japan. In this game you need to fill all cells with numbers. Some cells can be filled initially, the rest is filled by the player. The game is very similar to the game "Sudoku", but it has a difference. On the playing field, in addition to numbers, there may also be signs (more, less). The sign between two cells means that one number is greater than the other. A correctly filled square must satisfy the following three conditions:
1. The numbers in each line should not be repeated.
2. The numbers in each column should not be repeated.
3. If there are signs (arrows) on the field, then the condition must be met. (One number is smaller than the other).

Levels.

In the program you can choose 6 difficulty levels (4x4, 5x5, 6x6, 7x7, 8x8 and 9x9). The larger the square, the more difficult it is to go through. If you play Futoshiki for the first time, we recommend that you start with a 4x4 square. At each level of complexity you will be offered 2000 unique game levels. The higher the number the more difficult. (Level 2000 is the most complex).

How to play?

To change the value of a cell - first select it, and then click on the numbers at the bottom of the screen to put a number in the cell. You can put several numbers in one cell at once, but the level is considered passed, when in each cell there is only one number. If you want to remove a number from the cell, select it and click the corresponding number in the bottom of the screen.

### 5/5 — Großer Spielspaß

*2026-08-05*

Perfekte App

### 5/5 — Merci

*2026-06-27*

Super jeu.  Tout est logique, pas de hasard.

### 5/5 — Great app for playing Futoshiki

*2026-05-23, version 3.0*

This app is great. I can play the 4x4 when I need a really quick game, the 9x9 when I want to challenge myself, or anywhere in between. I can close it down and resume where I left off, which is so convenient. Plus, this is much more challenging than Sudoku. I also don’t feel embarrassed playing in public waiting areas, versus many other apps, because it is an app used to increase my brain functionality, not decrease it.

### 5/5 — Yes

*2026-04-10, version 2.8*

I been playing this game for many years and the app never failed me it always works and is easy to navigate

### 5/5 — Favourite!

*2026-02-02, version 2.8*

Fantastic app! I play every day.

### 5/5 — Download this now!

*2026-01-17, version 2.7*

I found this type of puzzle on a random site while looking for puzzles and fell in love immediately. Then it turns out there's an app with over 12k of them... sign me the fluff up. I'm 30 levels into the 4x4's so far and my brain hurts but dang is it not addictive to play. Probably going to buy the ad-free version since it seems to be a onetime payment even though I have ran into an add, it just seems they have a lot of puzzles on that version that aren't just this version that I would love to try. It's similar to sudoku (something I love already) but a bit more annoying but sorta more rewarding in my head since it clicks easily for some reason. 10/10 STARS!

### 3/5 — Well laid out not all puzzles solvable

*2025-09-21, version 2.7*

Love Futoshiki but several of these puzzles can’t be solved by logic alone. You end up having to guess based on narrowed down options and playing it out. Prefer one that is by logic, which is how it should be if well designed.

### 4/5 — It's okay.

*2025-07-09, version 2.7*

When you put in a large number the small number in the column and row should disappear. And you should be able to highlight the small and large numbers when you touch one number.

### 5/5 — Niveau 8 Jeu 268

*2025-05-19*

Impossible de résoudre cette grille. Il semble qu’il y est une incompréhension sur la troisième colonne. 🙃

### 5/5 — Une drogue!!!

*2025-05-06*

Ça doit bien faire cinq ans que j’ai ce jeu que je joue quasiment tous les jours et que j’ai terminé hier la grille en neuf, voilà voilà comme dans le titre une drogue !
