CryptoMath is a puzzle game where you exchange digits in the given system of basic equations to make it correct. All identical digits should be replaced with the identical ones.

This puzzle has much in common with cryptograms, but it has its own benefits:
- it doesn't require knowledge of any particular language, it uses the language of mathematics
- it improves your mathematical skills
- it allows you to practice mental addition, subtraction, multiplication
More over, there are only 10 digits, so it seems to be much more easy than playing with letters.

This app has several packs of puzzles. Each pack starts with rather simple puzzles, but the more puzzles you solve, the more difficult they become. All the puzzles in any pack are unlocked, so you don't have to solve them all to get to the last ones.

If you are stuck with a puzzle, you can use hint to get all the positions of a random digit in the system.

No internet connection required.
More packs will be available soon.
