N-Back Trainer

🧠 N-Back Trainer — Sharpen Your Working Memory

The N-Back task is the only brain training exercise with peer-reviewed scientific evidence for improving working memory and fluid intelligence. Now you can train anywhere, anytime.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━

🎯 HOW IT WORKS

You'll see a sequence of letters or positions, one at a time. Your job? Decide if the current item matches the one from N steps ago.

Example (2-Back):
F → K → F → …
The second F matches the F from 2 steps ago — tap MATCH!

Simple to learn. Incredibly hard to master.

🕹️ TWO GAME MODES

📝 Letter Mode — Remember sequences of letters
📍 Position Mode — Remember positions on a 3×3 grid

Each mode trains different aspects of your working memory. Letter mode challenges verbal memory, while position mode targets spatial memory.
