Project Euler Level 13 Badge
I reached Level 13 (325-349 problems solved out of over 950 at the moment). To put this in perspective, there are 37 levels. However, even Level 13 has fewer than 200 members at the moment (November 2025), and Levels 13 through 37 have about 1,050 out of a total 132,800 members.
The problems are very challenging, and I admire how clever some people’s solutions are (you can browse others' solutions after you submit your own correct answer).
It’s a great learning experience if you want to push coding to the limit and tackle problems involving huge numbers. However, brute-force approaches seldom work, so you also need to consider the mathematics involved.
