Dr. Mario

Dr. Mario is a falling block tile-matching video game, in which Mario assumes the role of a doctor, dropping two-colored medical capsules into a medicine bottle representing the playing field. This area is populated by viruses of three colors: red, yellow, and blue.

In a manner and style considered similar to Tetris, the player manipulates each capsule as it falls, moving it left or right and rotating it such that it is positioned alongside the viruses and any existing capsules.
