In my previous blog, I mentioned we probably (with hope) end with platforms like Mathforces. Not long after the blog, a guy shared SolveFire with me that is basically "Codeforces, but for math".

So today, I want to introduce this "Mathforces" and here it is:

The UI is super clean and modern. It obviously has both light and dark modes, which you can toggle by clicking the little "orz" guy in the top right next to your notifications. Did I really need to mention that? Yes, because orz.

Like any good Mathforces, it revolves around contests. Looking at the archives, the oldest contest dates back to February, so the platform probably launched in late 2025 or early 2026. They host weekly rounds featuring Bronze, Silver, and Gold divisions, and sometimes even Platinum and Diamond.

You can create your own community contests, and of course, upsolve problems you missed after the official round ends. The problems themselves are split into two types: answer-only and proof-based.

• Answer-only: You just type in the correct answer and it gets judged automatically.

• Proofs: You have to upload a document containing your proof. I'm not entirely sure who grades these, I'm guessing it's a mix of the problem authors and AI.

The contests are fully rated with a leaderboard, exactly as you'd expect. Another nice touch is that SolveFire separates the community chat from the blogs. This is a great feature for avoiding the spammy blog posts we sometimes see on CF (though to be fair, SolveFire doesn't have a massive amount of blogs just yet).

You can join the Discord server here.

I am going to reuse my words from my other blog cause I am lazy "Right now, there are very few active users since it is a brand-new platform. But I honestly believe it is going to grow to be just as big as the Codeforces. I think it will be a really great resource, not only for Math Olympiad, but also for CPers, since it really helps to build a solid math background and sharpen our logical reasoning..."

I highly recommend giving it a try, it's a great way to level up your logical thinking or just have fun(again)!
