The Devil's Calculator

The Devil's Calculator is an educational math experience posing as a casual indie puzzle game. Advanced graphing mechanics, countless features and simple, yet innovative level design provide considerable depth to the game play. Rather than the typical scenario of solving for x in an algebraic expression, imagine that the operators themselves are unknown. Each level requires deciphering the function of a mysterious operator and using it to calculate the number of the beast, 666, to progress. Only by gathering data can you work backwards to determine the obscure workings of the function and use it to purge the calculator of its demons. The player doesn't have to be a math prodigy; the game engages logical thinking skills. With an in-depth level creation system for players to program their own brain-teasers for the community, a DLC showcase features levels by leading mathematicians, professors and celebrities within the field, including James Grime of Numberphile and James Tanton of the Global Math Project. The Devil’s Calculator is completely free to educators and students, and 20+ levels are free to play for all. The Devil's Calculator spreads math appreciation and excitement in the form of an addicting and innovative puzzle game. (Available on iOS, Android and Steam.)
