## What is OMPN OneMinutePrimeNumber?

It's a simple game where you increase your score by factorizing prime numbers.
The difficulty level of the questions gradually increases.
 (Difficulty level mainly changes depending on the variation of prime numbers used as answers and the number of prime numbers.)

Three blue buttons help with difficult questions.(However, the three blue buttons can only be used once.)

- Extend the time limit(15 seconds).
- Change the question.
- The correct answer will be displayed for only 3 seconds.

I hope you enjoy this app!
