The Devil's Calculator

The Devil's Calculator is a non-profit, educational maths experience masquerading as a casual indie puzzle game, free to download for iOS, Android, Mac, Windows or Linux. Based on machine learning concepts, players interpolate unknown and obscure functions using sophisticated logic and reverse engineering after an evil calculator has had its normal arithmetic operators replaced with sadistically obscure functions. To excise the device of its demons, you must perpetually calculate 666, strategically collecting data and recognizing patterns in the output of the calculator. Advanced graphing mechanics and deep integration with professional tools such as Wolfram and Weka help you in your journey and make the experience accessible, not mathematically erudite. Puzzles are contributed by some of the world's leading mathematicians including bestselling author and Guardian puzzle editor Alex Bellos, Grant Sanderson of the highly popular 3Blue1Brown YouTube channel, Numberphile's James Grime and others, all levels apropos of their work and research in the field. An in-depth level creation system for sharing with the online community guarantees hours of challenging and rewarding gameplay well after the main campaign.
