Dr. Mario — About this game
Guide two-part vitamin capsules into a bottle of viruses. Align at least four matching segments or viruses horizontally or vertically to remove them, then clear every virus to finish the stage. Loose capsule halves fall after a match and can start chains. Choose the virus level and falling speed separately, and leave the bottle's neck open so new capsules can enter.
