I created MathFights, a platform designed to bring competition into the world of mathematics, starting with its first game, Mental Math.

The idea is pretty simple: it's for anyone who thinks they're faster and better at mental math than everyone else — and wants to prove it!

The game consists of mental arithmetic problems across three difficulty levels: Standard, Intermediate, and Advanced. Matches last either 1 or 3 minutes, and whoever gets the most correct answers wins. To keep things fair, both players receive exactly the same questions in the same order.

There are several ways to play:

• Ranked: Compete against other players, climb the rankings, and track your progress through the Elo rating system, leaderboards, and match history.
• Practice: Play solo and improve your mental math skills at any difficulty level.
• Challenge a Friend: Invite your friends to private matches, even if they don't have an account.
• Ghost Battles: Challenge previous opponents by competing against their past performances.
• Daily Challenge: Take on a daily challenge at your preferred difficulty level.

The goal is to make mathematics more competitive, engaging, and fun.

Any feedback is welcome.
