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).


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.

Great App

I like using this app, I’ll echo another’s comment saying that a button to check if all current values are correct would be nice. Also, if there was a different mode to pencil in potential numbers and one to put the actual number, I find myself getting confused when removing all potentials and making sure just the actual one stays.

Why so slow now?

I used to love this app, but after the latest update (August 2019) it slowed down so hard! There’s a delay now between selecting a number and seeing it in the square. I have to wait a beat or two between each number and I find it skips a lot of numbers I typed. I used to like playing a quick game, but now it’s just frustrating.

BTW, I waited to post this review because I thought maybe it was slow due to my old iPhone 7, but I just got an iPhone X and it’s still just as slow.

I would have given this five stars in the past for clean, quick game play with no distracting graphics and no waiting for ads. I might have downgraded it to four stars because my progress would be erased randomly. But now it gets only three stars because it’s so painfully slow.

Please make it fast again like it was before the last update!

Quick and Fun

I am enjoying this game. I like the choice of levels, and you can move from level to level whenever you feel like having a harder or easier game. I thought the larger games would be really difficult, but once you catch on, they are not. Others have mentioned that the game does not keep track of their progress, but I haven’t experienced that.
