Dr. Mario is a 1990 puzzle video game developed and published by Nintendo for the Nintendo Entertainment System, Famicom, and Game Boy. It was produced by Gunpei Yokoi and designed by Takahiro Harada. The soundtrack was composed by Hirokazu Tanaka.
It is a falling block puzzle game, in which the player's objective is to destroy the viruses populating the on-screen playing field by using colored vitamin capsules that are automatically tossed into the field by Dr. Mario. The player manipulates the falling capsules, to align the same colors, which destroys viruses. The player progresses through the game by eliminating all the viruses on the screen in each level.
Dr. Mario was a commercial success, with more than 10 million copies sold worldwide across all platforms. It received generally positive reviews, appearing on several lists of "Best Nintendo Games of All Time". It has been ported, remade, or had a sequel on every Nintendo home console since the NES, and on most portable consoles, including a re-release in 2004 on the Game Boy Advance in the Classic NES Series. It was modified into minigames in WarioWare, Inc.: Mega Microgames!, Brain Age 2: More Training in Minutes a Day!, and Brain Age: Concentration Training. Dr. Luigi is a spin-off for Wii U, released in 2013 as part of the Year of Luigi celebration.
