It's an action-puzzle video game released in 1990. Same as a falling block puzzle game, your goal is to destroy the virus that populates the screen with the help of coloured capsules thrown in by the doctor Mario. You have to manipulate the capsule while they fall, and you have to align them with similar colours, that is what kills the virus. If you match a line of the same colour of four or more than that, it will wipe out the viruses. Once you wipe out every virus, then you can move to the next stage. If you allow the pills to stack up the bottle, then you lose. The viruses are of three different colours: red, blue and yellow. Dr Mario stands to the right and tosses the capsules of the same three colours. The fun in Dr Mario is it requires a deep concentration to clear the viruses that fall faster and faster. You receive points for removing the virus, and if you clean up numerous viruses at one time, you get double, triple and quadruple points.
Mario takes the role of a doctor, tosses coloured medical capsule to clear the virus in the playing field, which is a medical bottle. The player can manipulate the capsules as it falls vertically at a time, he/she can rotate it 90 degrees clockwise or counterclockwise or left and right. The main aim is to complete the levels, which the player accomplishes by eliminating the viruses from the field. After completion of every 5th level, up to twenty cut-scene comes. In that scene, the virus trio sits on a tree, and some object glides over the screen. In the beginning, the player chooses the game speed and music. The score depends on the elimination of the virus.
