N-Back Working Memory Game
Decide whether each new letter matches the one from N steps back. Free, no signup, works on any device.
How to Play
- 1A letter appears one at a time. Recent letters stay visible so you can count back.
- 2Decide if the current letter matches the letter from N steps back.
- 3Tap Match if it is the same, or Different if it is not.
- 4Lower levels are 1-back; later levels move to 2-back and then 3-back.
N-Back asks you to keep a short stream of letters in mind and update it with every new item. That updating loop is the same working-memory skill used when you hold a phone number, a set of directions, or the last few words of a sentence.
About This Game
N-Back is a classic working-memory task: you see one letter at a time and decide whether it matches the letter from N steps earlier. That sounds simple, but it asks your mind to keep a moving window of recent items, drop the oldest one, and add the newest one after every answer.
A trial is correct only when Match or Different matches the true N-back relation. Guessing is easy to notice because the recent letters stay on screen so you can count back and check. Early levels use 1-back (compare with the previous letter). Higher levels move to 2-back and 3-back, which need a slightly longer mental window.
Short rounds are enough. Two to five minutes is a comfortable practice dose. The game is for anyone who wants a calm, focused memory workout — students, adults, and curious players — not a medical test and not a promise of special results. Play for the feeling of keeping a sequence in mind, then come back another day.
