Project Euler is a website devoted to computational problems that are intended to be solved through the use of computer programs. Adults and children interested in mathematics and computer programming are attracted to the project. Since its inception by Colin Hughes in 2001, Project Euler has earned notoriety and widespread popularity worldwide. It now contains 776 problems, with a new problem being published typically every two weeks. The problems are of varying degrees of difficulty. Still, each can be solved in less than a minute of CPU time with an efficient solution on a machine with a basic processing capacity. According to Project Euler’s latest statistics, as of April 27, 2021, it has more than 1,000,000 users who have solved at least one problem in more than 100 different programming languages.

After the user has correctly answered the question, they will visit a forum dedicated to that particular question. Problems can be sorted based on ID, and numbers can be solved or tough to figure out. Participants can keep track of their progress by achieving different levels of achievement based on the number of problems they have solved. Every 25 challenges solved results in the achievement of a new level. There are special awards given out for tackling specific combinations of challenges. For example, there is a prize for answering fifty prime numbered puzzles, given out annually. To track achievement, a unique “Eulerians” level is maintained based on the quickest fifty solvers of current problems, allowing newer members to compete without having to solve earlier problems.
