Mario trades overalls for a lab coat in Dr. Mario, a 1990 puzzle game released on NES and Game Boy at the same time. Red, yellow and blue viruses sit at the bottom of a medicine bottle, and Mario tosses in two-colored capsules called megavitamins. Lining up four or more segments of one color, vertically or horizontally, clears them, and a stage ends when every virus is gone.
Unlike Tetris, the objective is removal rather than survival, so each level is a small puzzle about where the viruses are placed. Leftover capsule halves fall when the piece beneath them clears, which allows chain reactions. Players choose a virus level from 0 to 20, a speed setting, and one of two songs, Fever or Chill, both of which became well known. Two-player versus mode sends garbage capsules to the opponent when combos land. Later versions include the SNES pairing with Tetris and the Game Boy Advance Puzzle League collection.
Tips for Dr. Mario
Keep the bottle's neck clear; a capsule that cannot enter at the top ends the game.
Stack capsule halves of the same color on a virus rather than covering it with mismatched colors.
Set up chains, where one clear drops loose halves into another match, to clear viruses faster and attack in versus.
