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.

Excellent Futoshiki App!

If you are looking for Futoshiki puzzles, with a full range from easy to the ridiculous 9x9 monsters, then this app is terrific! It does not try to do anything more - there aren’t any sudoku, kakuro, or any other types of puzzles- so if you are looking for anything other than Futoshiki puzzles then this is not for you.

Here’s what I like about this app:
• Those 9x9 puzzles are so challenging that they take me an hour to finish
• It is very easy and intuitive to make notes of the possible values for each square. As the puzzles get more challenging, then those notes are essential
• The app will automatically warn you if happen to enter the same integer twice in any row or column.
• The app simply works. I have yet to encounter any bugs.
• It’s free, without any in-app purchases or mandatory commercials! Banner ads across the top are a small price to pay for a quality app.

I hope the developers add more puzzles in the future!

Great puzzles, buggy app

I love how large the database of puzzles is—that’s an amazing feature. Some bugs: the level chooser screen is very, very laggy on iOS, and the puzzles a little laggy. The size chooser screen is largely fine. The level chooser screen also doesn’t preserve which levels you’ve completed between times the app is closed for any length of time. This is a bit frustrating, as you have to remember where you were and scroll (slowly because of lag) down to select by memory. Also, not a bug, but I’ll echo another user’s review saying that the modes to mark a number and to mark possible numbers are a little confusing. If you’re switching back and forth between using those two strategies, it’s a bit of mental gymnastics to remember to select everything but the number you want from the potentials but select the number you want for a blank square. It just ends up taking longer and is a bit annoying. I’m sure that goes away with time, but it could be smoother to start. Otherwise, great puzzles, and love the game!

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.
