Connect 'Primes' and calm down

By Shin Hirota

This app is only available on the App Store for iOS devices.


This application is a casual action puzzle game that decomposes numbers (prime factorization) and disappears by connecting them.
It is also ideal for brain training!

[How to Play]
- If the number falling from the top is not a prime number (composite number), decompose it until it becomes a prime by tapping.
- When two or more prime numbers are on the screen, you can erase prime numbers by swiping.
- When prime numbers are deleted, the following points are added:

(Score) = (Sum) x (Factor)
 (Sum): Total of swiped numbers.
 (Factor): The power of a prime number when two or more same prime numbers are included.
In case two or more types of primes included, the greatest one will be chosen.

2, 2, 2, 5, 7 are swiped:

(Sum) = 2 + 2 + 2 + 5 + 7 = 18
(Factor) = 2 ^ 3 = 8
(Score) = 18 x 8 = 144

- Game will be over when numbers are piled up and crossing the light blue line at the top.
- The maximum score is 9,223,372,036,854,775,807.
