Dual N-Back
A genuinely demanding working-memory exercise. Watch the grid and listen for a spoken letter each round, and flag when either one repeats from a set number of steps back. Sessions start at Level 2 and adapt automatically as you play.
Research-basedBased on the dual n-back task, one of the most studied paradigms in working-memory research -- though whether n-back training improves broader cognitive ability beyond the task itself is still actively debated among researchers.
Watch the highlighted square and listen to the spoken letter each round. When the square's position matches the one from N steps back, press Position Match. When the letter matches, press Sound Match — both can apply on the same trial. Sessions start at Level 2 and adjust automatically: strong rounds raise the level, tough ones lower it.
