## The Devil's Calculator Description
An evil calculator has its normal arithmetic operators replaced with sadistically obscure functions. Using logic and algebraic puzzle solving, you must work backwards to interpolate them and purge the calculator of its demons. 

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 along with several DLC levels, authored by famous mathematicians like Alex Bellos, Grant Sanderson, James Grime, Tony Padilla and James Tanton! The game was named a fan favorite of GDWC, and one of the top 10 indie games of 2019 by PAX.

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. The game was celebrated at the MOVES conference by the National Museum of Mathematics in New York City.

## The Devil's Calculator Reviews in United States

### **--- "Problems"
Ads

Completely frustrating operations

Me having to skip levels
-- UnWhPlTh, 2026-03-27

### ****- "Truly an educational game"
Unlike most attempts, which can more accurately be described as “educational” game or educational “game”. I’m genuinely having fun while also brushing up on my math and logic. Who knew the number 666 could provide such a wide variety of puzzles.

Update: knocking off a star because some of the late puzzles with the third operator get too tedious with too much trial and error
-- Lingrush24, 2026-01-28

### ***** "Insane"
Most creative idea ever
No ads(besides ones that you can close immediately and self promote their other games)
Fun
Best game for no wifi(however if you don’t have wolfram downloaded you can’t use it)
-- aircoins fan, 2025-12-31

### **--- "Why?"
Cant use devils calculator as a calculator instead you have a second basic and bland calculator. interesting concept, actual calculation interface ruins the immersion.
-- SrUser#69, 2025-09-07

### ***** "It’s bad just a loading screen σ_σ"
UPDATE NOWWWWWWWW
-- B. P. Harris, 2025-07-25

### ***** "Amazing"
This game is exactly how my brain works out formulas in math. Ive never been amazing at math but I’ve always tried to explain to people that my brain thinks math in an unorthodox way. The Devils calculator is how my brain works out math in a nutshell. This is groundbreaking for me.
-- Riloriles, 2025-02-13
