๐Ÿง  N-Back Test: Measure Your Working Memory Span

Letters appear one at a time and you decide, each time, whether the current letter matches the one N steps earlier โ€” starting at a single step back. A block runs twenty trials: clear 75% and N goes up, drop below 50% and the test ends. Skipping a trial counts as a miss, and your score is the highest N you cleared. Most healthy adults settle around 2-back.

๐Ÿ’ก How to play โ€” Letters appear one at a time, and for each one you say whether it matches the letter that appeared N steps earlier โ€” starting at just one step back. A block runs 20 trials: clear 75% and N goes up by one, fall below 50% and the test ends. Not answering counts as a miss, so commit to a button on every trial. Your score is the highest N you cleared, and the keys A and L work as shortcuts.
