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. [Example] 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.
