There are tons of brain training games out there, but I've never heard of one that works as well as DRUGS before.
Researchers at the University of Cambridge in England recently created a brain training game called Decoder, where your goal is to spot sequences of numbers.
And they just ran a study where they had people play the game for a little while, and then take a test.
They found that it temporarily boosted people's concentration so well, it was as effective as taking RITALIN. If you're not familiar, Ritalin is what they give people with ADHD to help them focus.
You can download an app with the game for free by searching for Peak Brain Training. It comes bundled with a bunch of other games, but as far as we know, they don't work quite as well as the Decoder game. Decoder is already included on the app for iPhones and should hit Android devices later this year.
