The Open Beta was launched a few days ago but improvements are still coming!
For example, Brain Storm Experts won't be a Facebook mini-game anymore, it will be integrated to Brain Storm and accessible via the Experts. Through this new feature you'll be able to earn bonuses, by linking your Facebook friends to your experts.
How will it work?
It's very easy: assign your Facebook friends to your experts, challenge them through the quizzes and earn energy bonus.
