Hello everyone!↵
↵
If you enjoy competitive programming and want that same adrenaline rush for math Olympiads, check out [MathJack](https://mathjack.org/) (The Olympiad Arena). It brings the Codeforces contest model straight into mathematics, hosting regular timed rounds across Beginner, Primary, and Intermediate tiers.↵
↵
The contest format scales with the division. Beginner and Primary rounds are answer-based, testing speed and accuracy on computational problems, while Intermediate rounds feature automated AI proof grading that evaluates full, rigorous mathematical arguments. Contests feature dynamic Elo ratings, live leaderboards, and a post-contest hacking phase to find counterexamples or logical gaps before ratings finalize.↵
↵
Most contests test the classic Olympiad quartet—one problem each from Algebra, Combinatorics, Geometry, and Number Theory—alongside occasional thematic rounds. You can explore the problem archives and register for upcoming rounds directly at [mathjack.org](mathjack.org).
