Comments on The Devil's Calculator: A Math for Android

★★★★★ Saxton Feiner · Dec 25, 2019
This game is simple to understand and challenges you in a way that doesn't feel hopeless. I would highly this if you like puzzles, want to practice your algebra and critical thinking, or if you just like problem-solving in general. The only complaint I have is that there isn't really a menu that lists all the levels that you have completed; for instance, if you want to return to a level that you've skipped, you'll have to recall that level's number off the top of your head.
★★★★★ xya green · Mar 31, 2023
