The PrimeGrid Challenge Series is an annual competition based on the results of monthly challenges. The purpose of the Challenge is to spotlight a specific project within PrimeGrid's family of projects as well as to offer a little "healthy" competition for PrimeGrid's participants. It is also an opportunity for people to learn more about each specific project and have fun doing it. Below is a tentative schedule for 2023.
