Dr. Mario is a non-tetromino puzzle game franchise developed by Nintendo and released on its systems.

The bottle is 8 blocks wide by 11 to 16 blocks high (depending on version) and starts out partially full of "viruses", or fixed blocks of the color red, yellow, or blue.

Pieces in Dr. Mario are vitamin pills with two halves (making them dominoes,) with each half colored red, yellow, or blue. The player can move or rotate them as they fall into the bottom. Once a pill locks, if four or more blocks of a color are aligned horizontally or vertically, they are removed, and the pill segments above them (but not viruses) fall in a cascade. In 2-player, cascades are worth more points.

Players who like Dr. Mario may also like Columns, Klax, and Puyo Pop. The game Tetris 2 can be thought of as Dr. Mario with tetrominoes.

Rotation system

Ordinarily, the pills rotate within a 2x2 box whose bottom left corner is always filled. Clockwise rotation looks like this:
