->''"The pills Dr. Mario throws to destroy the viruses are in fact the major threat. The viruses in the bottle can never actually do any harm. In fact, it is the pills that can do harm, causing the player to lose the game if they obstruct the neck of the bottle. Thus Dr. Mario is, as a game, one about [[MistakenForProfound bad medicine.]]"''\\

Around the time of ''VideoGame/{{Tetris}}'', ''Dr. Mario'' cashed in on both that puzzle game's fame and the fame of [[SuperMarioBros Mario]], while providing an intelligent twist on both.

Mario in this game has changed from a plucky plumber to a determined doctor who has to destroy all of the viruses (red, yellow and blue ones). He uses a series of capsules to eliminate them (when four capsule pieces/viruses of the same color line up in a row).

''Dr. Mario'' proved just as addictive as its puzzle game parent. "[[http://www.youtube.com/watch?v=8CB1fFeb1n8 Fever]]" and "[[http://www.youtube.com/watch?v=RsBtQCDbTWc Chill]]", the game's two main themes, are almost as iconic as "[[VideoGame/{{Tetris}} Korobeiniki]]". Two other tunes, "[[http://www.youtube.com/watch?v=MfCfVDJ-2PU Cough]]" and "[[http://www.youtube.com/watch?v=yW2dRDHWuj4 Sneeze]]", have also been present since the N64 iteration.

The game made an appearance as a minigame in both ''VideoGame/{{WarioWare}} Inc.: Mega Microgame$'' ("Dr. Wario", which is pretty much a sprite swap of the NES version) and ''BrainAge'' ("Virus Buster", which introduced touch controls to the series). Dr. Mario himself has showed up in ''VideoGame/SuperSmashBros Melee'', and the viruses appear as enemies in ''[[VideoGame/MarioAndLuigiSuperstarSaga Mario & Luigi: Superstar Saga]]'' and ''[[VideoGame/MarioAndLuigiDreamTeam Mario & Luigi: Dream Team]]''.

This game has been on the following systems:
* NintendoEntertainmentSystem
* GameBoy
* SuperNintendoEntertainmentSystem (in a double pack with ''VideoGame/{{Tetris}}'')
* {{Nintendo 64}} (''Dr. Mario 64'', which for some reason featured characters from ''VideoGame/WarioLand3'' as opponents)
* GameBoyAdvance (in a double pack with ''[[VideoGame/PanelDePon Puzzle League]]'' and as the aforementionned "Dr. Wario")
* NintendoGamecube (''Dr. Mario 64'', as part of the [[NoExportForYou Japan-only]] ''Nintendo Puzzle Collection'')
* WiiWare (''Dr. Mario Online Rx'', an online-capable version)
* {{Nintendo DS}}[=iWare=] (''Dr. Mario Express'' on the [=DSi=]'s Virtual Console)
* WiiU (''Dr. Luigi'', a MissionPackSequel to ''Dr. Mario Online Rx'' which celebrates TheYearOfLuigi by replacing Mario with Luigi and introducing the "Operation L" mode)

!!This series provides examples of:

* AnIcePerson: Chill, the Blue virus.
* AscendedExtra: In most media outside the game, the Viruses are given their own powers and personalities relating to the sickness they instill. Two of them are also named after the tunes in the game, the other one being "Weird", the Yellow Virus. In the games, they're simply obstacles.
* CanonDiscontinuity: Not that Franchise/SuperMarioBros has much of a canon, but according to a 2012 [[WordOfGod interview]] with ShigeruMiyamoto, Mario's time as a doctor was "not necessarily legitimate".
* ColorCodedForYourConvenience: It's a color-match puzzler, so...
* ComicBookAdaptation: "[[http://www.mariowiki.com/The_Doctor_Is_In..._Over_His_Head The Doctor Is In... Over His Head]]" from the ''ComicBook/NintendoComicsSystem'' explains to us how Mario got to be a doctor.
* ContinuityNod: Not necessarily in this game, but all three viruses have been featured as enemies in the ''Mario and Luigi'' series.
** In ''Superstar Saga'' they change into different viruses, an are taken out all at once when matched up. In addition they also power up another enemy called an Eeker.
** In ''Bowser's Inside Story'' a Blue Virus is spat up by Toothies as an attack. They stab Bowser with a spear if they reach him in time.
** ''Dream Team'' has them as enemies again, with the same matching color gimmick.
* DressedToHeal
* EasyModeMockery: In ''Dr. Mario 64'', when playing Round 7 in Easy Mode, it's just you and the Hammer-Bot from ''Wario Land 3''. But in higher difficulties, it's a free-for-all between the aforementioned, your rival, and Mad Scientists. You also can't face the {{Perfect Run Final Boss}}es in Easy Mode. Interestingly, Easy Mode also creates a case of WhatHappenedToTheMouse when playing as Wario in the opening for the final round, Dr. Mario is seen entering the castle after Wario, but doesn't show up again after that. In the higher difficulties, however, Dr. Mario just sits there dazed from the free-for-all battle as Wario enters the castle without him.
* FallingBlocks: Well, falling pills.
* HospitalHottie: [[AllThereInTheManual As seen in the manual for the game]], Princess Peach is a nurse at whatever clinic Mario oversees.
* NintendoHard: Good luck.
* NoEnding: The "Fever Clear," "Chill Clear," and "Game Over" songs go on for several seconds before abruptly cutting off.
* PerfectRunFinalBoss: ''Dr. Mario 64'' has two. If you beat the game as either character, you face [[spoiler:his rival, who has just ingested the megavitamins, resulting in either Metal (Dr.) Mario or Vampire Wario]].
* ShrunkenHead: [[http://www.youtube.com/watch?v=eUC058AGV6M A commercial]] had a guy telling how he beat a witch doctor at the game, and got his [[SoreLoser head shrunk as a result]].
* WithLyrics: [[http://www.youtube.com/watch?v=pc-EP-0xEDQ Of the background music]].
