Working memory
Dual N-Back
Two streams at once — a position on the grid and a spoken letter. Your job is to catch when either one repeats from N steps back.
How to play
Watch the grid
A square lights up in a 3×3 grid. Remember where it was.
Listen for the letter
At the same time, a letter is spoken aloud. Hold both in mind.
Press when it matches
If the position or letter matches what appeared N steps ago — press the key.
