The Devil's Calculator 4+

Don’t get me wrong the game is great, it’s just that there’s unfortunately an exploit I accidentally discovered that allows you to bypass any level. It involves plugging in one attempt, then using the calculator function you get from holding the screen type in an equation that results in 666. Due to the game plugging the answer you get from the calculator function into the puzzle calculator and you had already previously typed out an attempt, the answer gets replaced with 666 allowing the player to click the equals sign and pass the level. Again this is a great game, and I wanted to bring this issue to the developer’s attention.

As someone whose never been very good at math, the puzzles in this game have forced me to learn a lot of new concepts. But the puzzles are designed in a way that compels you to learn. There is always a skip button, but I rarely feel inclined to use it, and instead, I try to learn the concept and beat the puzzles legitimately. It’s rare that I find a puzzle game related to math, that I really want to play and continue playing, but this is that puzzle game.

With 70 levels in the base game, and plenty more in the dlc, there are plenty of opportunities to learn.

5 stars on all fronts.

Easily more fun, challenging, and educational than any math class I've been in. I'm getting ready to go back to school and this math game has been helping me a ton. The sheer joy of figuring out a pattern is just so good. And it forced me to look up math concepts I forgot about so now I remember factorials and base conversions...and some other stuff I may have never learned. Being able to buy a game outright with no ads or "energy" is also a real breath of fresh air. More games like this please.
