N vs Cozy Fish

Dual N-Back is a scientifically-backed cognitive training game designed to strengthen your working memory and fluid intelligence. First introduced by Wayne Kirchner in 1958 and popularized by Susanne Jaeggi's landmark 2003 research, the N-back task remains one of the most studied tools in cognitive neuroscience. Each round, you're shown a sequence of positions on a grid and hear a sequence of spoken letters. Your goal: identify when either the position or the letter matches what appeared N steps earlier. As your accuracy improves, the game advances your N-level — pushing you further. Game Modes: Dual N-Back lets you track both auditory and visual stimuli simultaneously — the most challenging and most studied mode. Single N-Back focuses on one stimulus type at a time, great for getting started or isolating a weakness. Silent Dual N-Back is visual-only, ideal for quiet environments. Adaptive difficulty adjusts your N-level based on performance. Score history lets you track progress over time. Light and dark mode included. Clean, distraction-free interface built for focus. No ads. No subscriptions. No nonsense. Whether you're a student, professional, or just someone who wants to stay sharp, Dual N-Back gives you a rigorous, research-grounded workout for your mind.
