"Robots! Bring me those beans!"

Dr. Robotnik's Mean Bean Machine (ドクターエッグマンのミーンビーンマシーン Dokutā Egguman no mīn bīn mashīn aka "Doctor Eggman's Mean Bean Machine"), also known as Dr. Robotnik and His Mean Bean Machine in European countries outside of United Kingdom, is a falling block puzzle video game that was 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. This is the only official Sonic spin-off that is set in the Adventures of Sonic the Hedgehog universe.

The game is a Westernized version of Puyo Puyo (1991), and replaces its characters with those from the Sonic the Hedgehog franchise, primarily those from 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 organizes colored shapes as they descend aboard.

This game is very faithful to Adventures of Sonic the Hedgehog from having the titular supervillain, Dr. Ivo Robotnik, and his iconic henchmen Scratch and Grounder (including the robot monkey, Coconuts). On every single level, nearly every single badnik from the very first episode of that show appears in the game.

Whenever you win a level, you get creative passwords that resemble each element in the game like the beans you use to win and the smiling Has-Bean. Whenever you lose, you are always given the option to continue without needing to necessarily start the game all over again. Despite how simple the game is, some of the levels can get extremely hard to pass them. For example, stages from Davey Rocket to Scratch's levels; but at least they're all playable, as stated before, you do get passwords to save your progress and you are given more than one chance to try again on a whim. If you happen to battle the badniks for a long amount of time, regardless of difficulty level, it speeds up and it also encourages you to find different chain combos for the beans you've been stacking.

The goofy and cartoonish nature of the game that matches the show is better seen during the levels. When the enemies' start making facial expressions as a way to communicate their confident or nervous reactions to winning or losing in a expressive way that are all done for comical effect.


Dr. Robotnik, the evil mastermind of planet Mobius, has hatched a new plan to menace the world and its inhabitants by kidnapping the citizens of Beanville and turning them into devious robot slaves, the doctor will create an army that will help him rid the planet of music and fun forever. To this end, he has created a giant robotizing machine called the "Mean Bean-Steaming Machine" to use on the jolly bean folk of Beanville.

Putting his plan into motion, Robotnik sends out all of his henchbots to round up all the unfortunate bean folk and group them together in dark dungeons so they can be sent to the Mean Bean-Steaming Machine. With help from Has Bean, the player must now stand up against Robotnik's henchbots by breaking into the dungeons, freeing the bean folk before it is too late, and get through the henchbots to the deranged doctor himself and foil his evil plans once and for all.

  • In the Game Gear version, Robotnik has plenty of wacky expressions while you battle him in this port, which can be also seen in the instruction manual for the Game Gear port; the latter being surprisingly faithful to Milton Knight's drawings he made when creating the character design model sheet for this take on Robotnik.
  • The game over screen in all versions of the game is based on the scene from the show's unaired pilot where Eggman informs his S.S.S.S.S. Squad about catching Sonic.
  • There was a whole entire level that is dedicated to this game on an actual Sonic game! As seen in Sonic Mania, there is a mini level and a boss battle in Chemical Plant Zone Act 2 where you get to face Robotnik in same style as Mean Bean Machine.
  • This version of Dr. Robotnik was one of the first video game villains to have mild voice-overs in the 16-bit era alongside the villains from Altered Beast. All with some decent voicing that contains laughs and one yell that was provided by Max Taylor to voice Robotnik himself.
  • While it is very faithful to the cartoon, there aren't that much references from the show aside from the titular villain alongside the recurring antagonists, the one-off robots that appear, and Robotnik's fortress (with the minor nitpick of Robotnik's missing golden statue of himself). As such, you never get to see a cameo of Sonic, Tails, or anyone else from that show. Especially since this game is still a part of the Sonic the Hedgehog franchise as a whole and AoStH fans may be wondering why other characters never appear in the game.
