The Devil's Calculator: A Math Puzzle Game

Offers in-app purchases

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.
