Success Stories
Feedback from people having positive results by doing Dual N-Back brain game
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… My productivity is much higher these days.
I’m a non-fiction writer, so having a higher working memory and fluid intelligence directly leads to better (and faster) performance. It’s amazing to see the stuff I produce today and compare it to before I began the Dual N-Back 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.
