PrimeBreaker is a fast number game where you break composite numbers by firing prime factors. Clear as many numbers as possible in 60 seconds. Correct prime factors split the target into a smaller quotient, while wrong shots bounce off and cost time. PrimeBreaker does not require an account, online ranking, in-app purchases, or special device permissions.
