Dual N-Back · dualnbacktraining.com

Welcome back.
Keep the streak alive.

Consistency is what makes dual n-back training work. Research shows the biggest cognitive gains come after 4–8 weeks of daily practice. Pick up exactly where you left off and continue your working memory progress at dualnbacktraining.com.

Peer-reviewed studies confirming dual n-back training improves working memory and fluid intelligence

Consistent daily dual n-back practice needed to produce measurable, lasting cognitive gains

No ceiling — the dual n-back task scales indefinitely; even elite users continue to improve at higher N levels
Why it matters

The science of
showing up daily.

01

Memory consolidation

Each dual n-back session reinforces the neural pathways built the day before. Gaps in training allow those pathways to weaken — daily practice is what turns short-term gains into lasting working memory improvement.

02

Adaptive threshold

The dual n-back game tracks your N-level across sessions. Missing days resets your calibration. When you return consistently, the algorithm keeps you exactly at your cognitive limit — where real learning happens.

03

Cumulative transfer

Research on the dual n-back task shows that transfer effects — improvements to untrained tasks like fluid reasoning and attention — accumulate over weeks, not days. Every login adds to the total.

Research

What scientists say
about coming back.

Psychological Science 2008 — Jaeggi et al.
"The relationship between the amount of training and the size of the gain was dose-dependent — participants who trained more showed greater improvements in fluid intelligence."
Jaeggi, Buschkuehl, Jonides & Perrig
The original dual n-back and intelligence study
Frontiers in Human Neuroscience 2014
"Working memory training effects were strongest in participants who completed the full training protocol. Adherence and session count were the strongest predictors of transfer to fluid intelligence."
Salminen, Strobach & Schubert
On the benefits of dual n-back training consistency
Neuropsychologia 2017
"N-back training produced significant improvements in attention control that persisted at a 3-month follow-up, suggesting that short daily sessions create durable changes in attentional networks."
Leung, Lee, Yuen, Lee & Cheung
Intelligence Journal 2019
"The dual n-back task remains the single most replicated working memory training paradigm with evidence for far transfer. Its adaptive nature ensures that training difficulty scales with the individual."
Soveri, Antfolk, Karlsson, Salo & Laine
FAQ

Returning user
questions

Will my progress be saved? +
Yes. Every dual n-back training session is stored in your account — your N-level history, accuracy per modality, session count, and streak. Logging in restores everything instantly. Guest sessions are not saved across devices.
What happens if I miss a few days? +
Your account and data are preserved permanently. Missing sessions breaks your streak counter but does not erase your progress. The dual n-back game will recalibrate difficulty based on your first session back — usually 1 level lower than your peak to reactivate the neural pathways.
Can I train on multiple devices? +
Yes. Your dual n-back training account syncs across all devices. Start a session on desktop, check your progress on mobile — everything is linked to your account in real time at dualnbacktraining.com.
How do I reset my password? +
Click "Forgot password?" on the login form. You'll receive a reset link at your registered email address within a minute. If you signed up with Google, you log in through Google — no password is needed.
Is the dual n-back game still free after logging in? +
Completely. All core dual n-back training features — unlimited sessions, adaptive difficulty, session history, and the global leaderboard — remain free forever. No subscription, no paywall, no credit card required.
I signed up with Google — do I need a password? +
No. If you created your account with "Continue with Google", simply click that button again. Your account is linked to your Google identity — no separate password exists or is needed.
