The Devil's Calculator is a captivating math puzzle game based on a narrative in which an evil calculator has had its normal arithmetic operators replaced with sadistically obscure functions. Using logic and a bit of algebra, you must work backwards to find the equation for the "number of the beast," 666, at each level. Innovative and addicting, this game will appeal to numberphiles and math novices alike.
The award-winning Devil's Calculator was chosen as a PAX Top 10 Indie Game in 2019.
