What Is Dual N‑Back?
Dual N‑Back is a working-memory exercise developed for neuroscience research. Some studies have linked regular practice to gains in fluid intelligence, though that transfer is debated — see what the research actually says.
It's a clean, faithful implementation of the task, free in your browser. Give it a try and see for yourself.

What Our Users Say
A few comments from long-time members of the community.
Not much, yet, but I feel that I can easier get a hold of a discussion.
The feeling is the same as when I am mastering a certain n-back in the game (a bit hard to explain).
I feel much sharper since I started in the middle of last November, and my day-to-day productivity feels higher.
I’m a non-fiction writer, so I notice it in the work — though of course a lot goes into that besides training.

How To Start Training?
First select a mind game you would like to play. Then visit the information page and the tutorial page, if needed.
Then just open the training page and enjoy playing ;)
All the exercises on the site are free and do not require registration. However, if you are planning to have continuous trainings on brain games we recommend you to complete a 2 minute free registration form here.
Motivation and Persistence
One of the biggest challenges our users face is not doing the exercises. It's to keep doing them. As, you know, benefits from brain training exercises don't come overnight.
This is why we've introduced Streaks - a feature that helps you keep track of your progress and motivates you to keep going.
Do not try to do too much at once. Start with 5-10 minutes a day and gradually increase the time, watching your streak counter growing along with your brain sharpness.
