Great app for playing Futoshiki

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.

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!

Well laid out not all puzzles solvable

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.
