Brainrot: Memory & Brain Games

Brainrot is a brain games app for memory and focus, built on dual N-back — the working memory training task most studied in cognitive science. Short daily sessions, no feeds, no ads.

Your attention isn't broken — it's just out of practice. Brainrot is the gym for it: a focused memory game that swaps the scroll for a few minutes of real brain training.

How the N-Back Memory Game Works
Watch a stream of stimuli and respond when the current one matches the item from N steps earlier. In 2-back, you match the item from two steps ago. Easy to learn, hard to hold — and that gap is exactly where working memory, concentration and focus get trained. As you improve, N goes up.

Brain Training With Endless Depth
• Single, Dual, Triple and Quad N-back — 1 to 4 streams at once
• Classic dual n-back: grid position plus sound
• Stimuli: numbers, letters, sounds, shapes, colors and grid positions
• 1x3 and 3x3 grids, 150+ combinations of visual and audio streams
• Adaptive difficulty: the N level rises and falls by rules you set
• Two audio streams at once, one per ear — a true dual-sound challenge with headphones

The Honest Part
N-back is real cognitive training, not a magic pill. We don't promise IQ points or medical outcomes — the results come from showing up and doing the reps.
