Dr. Robotnik's Mean Bean Machine is a puzzle game for the Sega Game Gear and Sega Master System. It is similar to its 16-bit counterpart for the Sega Mega Drive, but contains an additional Puzzle Mode that is not present in the Mega Drive version. This version was included as an unlockable game in Sonic Adventure DX: Director's Cut, and later as a default game in the compilation Sonic Mega Collection Plus (which itself featured in later compilations).

For information on the storyline and gameplay common to both versions of the game, see the article about the 16-bit version.


Scenario Mode

This is the game's story mode, in which Has Bean must "Battle Robotnik's ranks of robot flunkies in order to save Beanville!" The player competes against computer-controlled characters in 13 stages. Most of these characters are also found in the pilot and 1st episode of the show, and each one is based on a corresponding character from the original Puyo Puyo game. The pilot even has a scene that looks striking similar to the continue screen in this game.
