🧠 Expert N-Back

Expert N-Back is a demanding, expert-level cognitive workout that challenges your working memory. The task is simple to learn but hard to master: judge whether each symbol matches the one shown N steps before. Across 13 rounds the game adapts to keep you on the edge of your ability, then rolls your performance into a single shareable Brain Score, a letter grade, and a playful estimated 'brain age' you can compare with friends. Unlike endless scrolling, a few focused minutes here genuinely exercises attention, memory and processing speed — and because it's quick, it's easy to come back daily and watch your score climb. It runs instantly in your browser on phone or desktop, keeps your best score, plays gentle audio cues you can mute, and respects reduced-motion settings. No download, no sign-up — just train your brain.
