About The Devil's Calculator
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 and use these corrupted operators to compute the 'number of the beast', 666, in order to purge the calculator of its demons and continue on. 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 in the game's Demo.
Each level has you decipher the function of a mysterious operator and use it to calculate the number of the beast to progress. The game features advanced graphing mechanics and access to various resources to help you interpolate and solve the innovative and creative function level design. As you progress in the game, 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 an addicting and gratifying puzzle experience.

Barely disguised math homework (said with love) i will forever know the prime factorization of 6661 found this helpful
Solid Game. The binary functions are a bit repetitive, but generally worth your money for the time you get out of that
Amazing puzzle game for math nerds! Great challenge, even if you (think you) know what you're doing. Some puzzles have really neat connections, and you can tell the devs have a lot of attention to detail! All 68 main levels are really cool and well thought out. Also 3Blue1Brown made a DLC problem that I haven't been able to do yet.
A great game to get the mind going. Only complaint that i have is that the built-in regular calculator kinda sucks, I have to resort using a different calculator so that my answer from one equation can easily be used in the next equation.
