Brain Drain — About this game
Rebuild the displayed symbol pattern by rotating groups of four tiles inside a movable frame. Each turn changes four positions at once, so solving one corner can disturb a section already arranged. Timed stages introduce effects such as reversed controls and hidden symbols. Clock and flash bonuses provide relief, but accurate planning and recognising the result of each rotation remain the main tools. Begin Brain Game and compare the target with the first board. Rotate one four-tile group with A and reverse it with B to learn the effect before planning several turns. Avoid holding a bonus button when you only intend a normal rotation.
