About N-Back Test

N-Back Test is a scientifically proven working memory exercise. It challenges your ability to remember and match positions from N steps back in a sequence.

How it works: Watch squares light up in a 3x3 grid. Press SPACE when the current position matches the position from N steps back. Start with 1-back (previous position) and work up to harder levels.

Benefits: Research shows N-back training can improve fluid intelligence, working memory capacity, and cognitive control. Used in cognitive research since 1958.

Tips for success: Start with 1-back, focus intensely, practice daily, don't guess randomly, and gradually increase difficulty as you improve.
