The idea for BrainDuel actually came from a deep love for Human Benchmark. I always loved testing my stats, but I kept thinking: how cool would it be to turn these cognitive tests into a competitive, high-stakes 1v1 esport? Instead of just trying to beat your own high score or checking a percentile graph, BrainDuel lets you test your reaction time, sequence memory, verbal memory, typing speed, and aim directly against a real opponent in real-time. Whether you just want a quick brain warmup or want to grind your way from Silver up to Gold, every match is a fast-paced battle of wits. The game is completely free and hosted on Vercel, so you can jump into a duel right from your browser. I’d love to hear your thoughts: - Which mini-game is your favorite (or hardest)? - What other cognitive tests or modes would you love to see added? I'll be around all day to answer questions, chat about the dev process, and jump into some matches. See you on the leaderboard!
