## About This Game
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.
## Features

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
