🧠 N-Back
The gold-standard working-memory drill used in real cognitive research. A letter appears — decide instantly whether it repeats the one n steps back.
🧩
2-back trains the same ability as juggling while answering questions. It is hard on purpose — most people plateau at 2, and 3-back is where real training lives.
Tap the big button or press Space when the letter repeats the one 2 back
