The most surprising thing about BrainBurst 1.3 is how a such a simple game can end up being so addictive. Basically you have to make the objects disappear (like Tetris) grouping them by colour and regrouping all of them to make them disappear.
Maybe its attraction lies in the fact that as you advance it gets more and more difficult, and a delicate, quick and authentic expert you must become to succeed.
Very entertaining, simple and controllable. What more can you ask of this type of game?
