Bonus Problems
Posted: Fri Sep 05, 2025 11:20 pm
I haven’t been solving PE in 8 years. A few days ago, I just returned and solved a few problems from the "Recent" list, which unlocked Bonus Problem #5 — and I managed to solve it, which was a lot of fun!
I’m wondering if Project Euler has publicly documented the rules for unlocking Bonus Problems? Also, is there a way to view the number of people who have solved a Bonus Problem or its difficulty rating?
