Numarena

What if mental math were a combat sport? Numarena is an arena where you go head to head with additions, subtractions, multiplications and divisions. Same calculation, same second, two brains: the fastest one wins. No endless levels to unlock, no lives to wait for — just you, a real opponent, and the clock running down. ⚔️ RANKED DUELS IN REAL TIME Start a search and find an opponent at your level in seconds. Every duel is played face to face, calculation after calculation, until one of you cracks. Your Elo goes up with every win and down with every loss: your rank is one you earn. 👑 BATTLE ROYALE Up to 8 players in the same arena. Knock them out, take the hits, hang on — only one can be left standing. The mode where you find out how much worse you calculate under pressure. 🤝 GAMES WITH FRIENDS Create a private room, share the code, and finally settle who's the fastest of the group. From 2 to 4 players, with a chat to comment on the damage. 🏆 GLOBAL LEADERBOARD A global ranking and detailed statistics: wins, accuracy, average response time, current streaks. Everything you need to see exactly where you're improving — and where you're stuck. 🧠 SEVEN SOLO MODES TO TRAIN • Endless — calculate without limits, at your own pace • Speed — every calculation has its own time limit, answer before the buzzer • Survival — three mistakes and it's over • Time Attack — a set time, as many calculations as you can solve • Ascent — tiers that get harder and harder, until you fall • Laboratory — your operations, your ranges, your timer: you set everything • Daily Trial — 9 calculations in 3 rounds, the same for everyone, once a day 🎯 DAILY CHALLENGES New goals every day to keep your rhythm and come back without thinking about it. 📈 WHO IS IT FOR? For pupils and students who want times tables and calculations that actually stick. For exam candidates who need to be fast without a calculator. For parents looking for something other than worksheets. And for anyone who just wants to keep their head sharp with a few minutes a day. ✨ NUMARENA PREMIUM The optional monthly subscription removes all ads, unlocks Ascent, Laboratory and the Daily Trial without limits, and gives access to advanced training settings.
