Competitive Math Game
Real-time battles, ELO ratings, and global leaderboards.
Prime 59 turns math into a competitive sport. The ELO rating system ranks you against other players based on your battle results, just like chess. Global leaderboards track the fastest solvers at each difficulty level. The daily challenge creates a shared competitive experience where everyone solves the same puzzle and competes for the top spot. Whether you’re racing a friend in Battle Mode or climbing the monthly leaderboard, Prime 59 delivers the competitive math game experience that keeps you pushing to improve.
