Number Memory

How sharp is your brain? Number Memory puts your working memory and reaction speed to the test — then gives you a Brain Age score that tells you exactly where you stand. TWO MODES. ONE BRAIN SCORE. 🔵 NUMBER MEMORY Numbered circles appear in random positions on screen. Memorize them. When they disappear, tap each one back in order — 1, 2, 3 — from memory alone. Every correct round adds one more circle. One wrong tap ends the game. Your Brain Age is calculated from the level you reached, your accuracy, and how quickly you responded. 🟢 REACTION TIME Five rounds. The screen flashes green — tap as fast as you can. Your average reaction speed is measured in milliseconds and your personal best is saved automatically. YOUR BRAIN AGE SCORE An algorithm combines your level, accuracy, and tap speed into a single Brain Age number, paired with a performance label: Legendary · Master · Expert · Great · Average · Almost · Keep Going · Try Again. A fun, honest benchmark to chase every session.
