Working memory training
You'll see a sequence of positions highlighted on the grid. Press the button when the current position matches the one from N steps back.
For example, in 2-Back, you press the button if the current position is the same as 2 positions ago.
Select difficulty:
Round 1 / 20
Press SPACE or click when position matches N steps back
Train your working memory with the N-Back task, one of the few cognitive exercises scientifically shown to improve fluid intelligence. Watch positions highlighted on a 3x3 grid and press the button when the current position matches the one from N steps back. Start with 2-Back and progress to more challenging levels as your skills improve. For another cognitive challenge, try our Stroop test to train selective attention.
The game presents a sequence of 20+ positions, with approximately 25-30% being matches. Your accuracy is calculated based on correct hits, missed matches, and false alarms. Choose difficulty levels from 1-Back (beginner) to 4-Back (expert) to match your current ability and track improvement over sessions. You can also test your spatial memory with our visual memory grid test.
Research suggests that N-Back training can enhance working memory capacity and may transfer to improved fluid intelligence, attention, and cognitive control. Working memory is fundamental to reasoning, comprehension, and learning. Pair this with our sequence memory game for comprehensive memory training. Regular N-Back practice is popular among students, professionals, and brain training enthusiasts seeking measurable cognitive improvement.
