Dr. Mario

Dr. Mario (ドクターマリオ, Dokutā Mario?) is a 1990 Mario action puzzle video game designed by Gunpei Yokoi and produced by Takahiro Harada. Nintendo developed and published the game for the Nintendo Entertainment System and Game Boy consoles. The game's soundtrack was composed by Hirokazu Tanaka.

The game focuses on the player character Mario, who assumes the role of a doctor and is tasked with eradicating deadly viruses. In this falling block puzzle game, the player is tasked with destroying the viruses populating the on-screen playing field with the use of colored capsules that are dropped into the field. The player manipulates the capsules as they fall so that they are aligned with viruses of matching colors, which removes them from play. The player progresses through the game by eliminating all the viruses on the screen in each level.

Dr. Mario received positive reception, appearing on several "Best Nintendo Games of All Time" lists. The game was either ported, remade, or has had a sequel on every Nintendo home console since the NES as well as most portable consoles, including a re-release in 2004 on the Game Boy Advance as part of the Classic NES Series. Modified versions of Dr. Mario were included as minigames in WarioWare, Inc.: Mega Microgames! and Brain Age 2: More Training in Minutes a Day!.
