Dr. Mario

Dr. Mario is a non-tetromino puzzle game franchise developed by Nintendo and released on the NES, Arcade, Game Boy, Super NES, Nintendo 64, Gamecube, and Game Boy Advance 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 dominoes, with each half colored red, yellow, or blue. The player can move or rotate them as they fall into the bottom. Once a piece locks, if four or more blocks of a color are aligned horizontally or vertically, they are removed, and the blocks above them (other than 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.
