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

★★★★★ Emilio Moreno · Feb 18, 2023
Great little puzzle game. The only flaw is that sometimes the controls aren't the most responsive, but I'm playing a game about an evil calculator, and the controls aren't so unresponsive that they hinder the experience - i.e., it's very easy to excuse. It's absolutely worth the premium upgrade if ya dig math puzzles.
★★★★★ Fractalator _ · Mar 4, 2020
I find all the levels really fun, and it makes you use your brain. My favorite aspect of the game is the funny story that comes along with it. It's also well-explained how to play with quite basic rules but fun challenging questions. Most of all it's ad-free. Also, it's totally free to go past Level 23 for students.
★☆☆☆☆ Bob Devlin · Oct 2, 2022
How is this"Award-winning" unless the award is "Worst Game of the Year"?
★☆☆☆☆ Zenda Renn · Jul 2, 2024
It's stuck on a white screen, I wanted to jump into this completely blind but not like THIS
★☆☆☆☆ Fred · Nov 6, 2022
Figuring out how to upgrade to the full version without a students email is a puzzle in of itself. Where is the "buy full version" button???
