DRMBM meaning in Computing ?

Dr. Robotnik's Mean Bean Machine is a falling block puzzle game developed by Compile and published by Sega. It was released for the Genesis/Mega Drive in North America and Europe in November 1993, and ported to the Game Gear in 1993 and Master System in 1994.

The game is a Westernised version of Puyo Puyo (1991), and replaces its characters with those from the Sonic the Hedgehog franchise, primarily the Adventures of Sonic the Hedgehog animated series. The Puyo Puyo character Carbuncle appears under the name "Has Bean" and makes different animations depending on how the player plays the game. The gameplay is similar to puzzle games such as Tetris, in which the player organises coloured shapes as they descend a board. The plot sees Sonic antagonist Doctor Robotnik kidnapping residents from Beanville and turning them into robots. The game received mostly positive reviews, with critics praising the gameplay but criticising the difficulty.
