How to play
N-back
Cards go by one at a time. Guess whether the card on screen is the same card you saw n back. n grows to 2 and 3 as the level rises.
Same · Different
Tap SAME if it is the same card, DIFFERENT if not. You get an O when right and an X when wrong. Letting a card pass without an answer counts as wrong.
Keyboard
