Description
An evil calculator has its normal arithmetic operators replaced with sadistically obscure functions. Using logic and a bit of algebra, you must work backwards to interpolate them and purge the calculator of its demons. This new, non-profit calculator game by the creator of Synonymy is sophisticated, and challenging.

Non-profit and open-source, The Devil's Calculator is a highly original indie game that's as addicting as it is educational. Accessible to numberphiles and math novices alike, the first 20+ levels are 100% free to play and enjoy.

Each level has you decipher the function of a mysterious operator and use it to calculate the number of the beast to progress. Advanced graphing mechanics, countless features and simple, yet innovative level design provide considerable depth to the gameplay. Players unlock the ability to create their own levels and play challenges others have created - including free DLC levels crafted by the game's creators, educators and mathematicians. With hand drawn artwork and a charming story, the Devil's Calculator is a genuinely fun and gratifying puzzle experience.

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

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???
