NBack Lite-Brain Game

NBack is a scientifically backed brain training exercise used in cognitive research to improve working memory and focus. Each round, a letter and grid position are shown one at a time.

Start at N=1 for a warm up, N=2 for a real challenge, or N=3 to push your limits. Choose your round length and go. Use the UP button to change round length. Use the DOWN button to change N level.
