Brain Drain

As you progress through the game, special effects become more challenging to deal with. "?" blocks hide symbols, symbols rotate on their own, or the controls are reversed in higher difficulty levels. To aid you, you can earn power-ups like clock (stops time for 20 seconds), flash (skips the current level), and credit (gives a second try after time runs out). The "Brain Race" mode requires solving a set number of levels as quickly as possible.
