Brain Training Games

Dual N-Back

A cell lights up and a digit is spoken at the same moment. If the position matches the one 2 steps back, tap 'Same position'; if the sound matches the one 2 steps back, tap 'Same sound'. A game that challenges holding two streams in mind at once.

How to play

  1. Each round a cell lights up and a digit is spoken. Turn your sound on.
  2. If the position matches 2 steps back, tap 'Same position'; if the sound matches 2 steps back, tap 'Same sound'.
  3. Stimuli advance on a fixed rhythm. If nothing matches, tap neither.
  4. The first 2 are just to remember. The more you get right, the higher your score.
