What Is an N-Back Test?
An N-back test is a working-memory task where you compare the current stimulus with the one from N rounds earlier. You can run it here directly in the browser, without downloading software or creating an account.
N-Back Test Online
Play an online N-back test in your browser, with no download and no signup. Use Single or Dual mode, move from 1-back to 4-back, and keep local scores on your own device.
Single and Dual N-Back Online
Use Single N-back when you want to track position only. Switch to Dual N-back when you want two streams at once: visual positions and spoken letters in the same session.
Single N-Back
In Single mode, one field lights up in a 3x3 grid. Press `A` when the current position matches the one from N rounds earlier. It is the simpler place to start if you are new to the task.
Dual N-Back
In Dual mode, the browser also speaks a letter. Press `A` for a position match and `L` for a sound match when they repeat at the selected N distance. The difference is not just more input, but more coordination under time pressure.
Adjust Difficulty Before You Start
Choose 1-back to 4-back, set the number of rounds, and use presets or a custom rhythm before each session. Lower N and a slower rhythm work well for warm-up rounds. Higher N and a faster rhythm make the task tighter and less forgiving.
Working Memory Task in the Browser
This version is made for quick repeat sessions in a browser. You can run the task on desktop, tablet, or phone and restart immediately with a different setup.
No Download, Local Results Only
Finished runs show hits, misses, false alarms, and accuracy. If you save a result, it stays in local browser storage on your device.
What This Page Helps You Compare
Use this N-back task to compare your own runs across different N-levels, modes, and rhythms. Treat it as a repeatable challenge, not as a medical or clinical diagnosis.
Want a Spatial Recall Variant Instead?
If you want a working-memory game with a visible route instead of repeating stimuli at N distance, try Memory Path. It focuses on remembering a path through a grid rather than position and sound matches. If you want a more practical daily-life task, try Money Counting.
Frequently asked questions
What is the difference between Single and Dual N-back?
Single N-back tracks one stream only: the visual position in the grid. Dual N-back adds spoken letters, so you monitor both position and sound at the same time.
Can I use this as an online N-back test?
Yes. You can run the task directly in your browser, choose the setup before each session, and save local results for comparison.
Can I play N-back on mobile?
Yes. The page supports keyboard shortcuts on desktop and large touch buttons on phones and tablets.
