The Devil's Calculator

Интересно занимает время, для тех кто любит математику сложно остановиться.

A real puzzle game with different problems to challenge you. One slight gripe, the “real” calculator malfunctions when you want to use the answer you got previously, like if I input “330 * 2”, getting 660, then pressed “+6” on the next row, instead of showing 660 + 6 = 666, it’d show 2+6 = 8 Still, awesome game!

My son and I have a passion for maths, and we had a blast playing through this game together. We enjoyed discussing the functions and sequences and trying to work them out. The app is a bit rough around the edges in terms of user experience, but I still have to give it 5 stars because of how much fun we had. Please release some more levels, I’ll happily pay for more!

Gets very tiresome, very quickly. The puzzles are arbitrary and unsatisfying, since the best strategy just seems to be repeated guessing.

This is a very great game! ^_^

Cool puzzles, and I can yeet the default calculator app now.

Enjoying it, but the graph to wolfram alpha function doesn’t seem to work. I love the puzzles though.

I like math

Really fun to sleuth for the answers and some levels are quite tricky!!! The built in calculator (when you press and hold on the display area )needs some work and button responsiveness isn’t always the best.

This game is infinitely clever and perfectly scratches that itch if you are looking for challenging math riddles. Most games like this do not scale the difficulty well, but this one manages to give you more and more tricky situations without feeling unfair. I greatly enjoy it and would recommend to anyone who enjoys math riddles or puzzles.
