At the beginning only some squares are revealed, the player must discover the rest.
Each puzzle has a unique solution and no guessing is required to discover it.

Futoshiki user reviews :

It’s ok if you like it simple. All the hard levels and all the boards greater than 6×6 are locked, released only if you pay. When it’s only easy levels you can play then the ads get quite tiresome as they appear after every game. That’s pretty frequent when the puzzles are so trivial. You will make mistakes though. Not through logic errors, just because the two sets of numbers you use for entry are so close to each other that unless you have matchsticks for fingers the wrong numbers will be hit

Mostly good. Some of the puzzles are very challenging which is good. I would like a couple more hints when the levels are difficult and you get stuck. Also I think there are too many levels you have to pay for. Great game though, better if you pay for all the levels. Which I’m not. More free levels please!!!

Love the game. The hard fill buttons are too close to the pencil fill buttons. It is easy to hit the wrong one by mistake resulting in the error warning and point deduction. I’d suggest putting one at top of board and other below. Also the error highlights things too quickly (i.e. immediately).Better to let game flow and let players find errors as they go. I’d also like to see a “clear board” key as well as a backspace. I haven’t paid yet to open all levels and remove adds but probably will.

the game time is affected by advertising so the only way to get actual times is to pay for the ad free version. also a significant portion of the games are not available unless you upgrade!!

  • Thank you very much for your review. After your complaint, I have changed the advertisement timing. In version 2.6 the game time is not affected by advertising. For the next version, I am planning to add more levels for users who did not upgrade.

Great UI, crisp graphics. More than worth paying to remove ads if you like puzzle games. Allows you to opt out of personalized ads as well.

Fun game. Many difficult levels allow everyone to enjoy the game.

Nice app! Could do with auto deletion of notes and ability to place multiple notes at one time.

Excellent game play and so many puzzles it will keep me going for years.

Great for keeping yourself engaged while helping stave off boredom when you need a way to pass the time!
