Story: With his newest machine, the "Mean Bean-Steaming Machine," Dr. Robotnik will transform the citizens of Beanville into robots. Robotnik's robots are grouping the beans into their dungeons to send them to their fate. As the player of the game, you are to move as many beans through your dungeon as possible. If you can make your opponent's dungeon burst open (i.e. filled with beans), you will move up the line of "henchbots" until you meet up with Dr. Robotnik.

Levels: The basic Scenario Mode consists of 13 levels, where there is one opponent per level. The order of the opponents is as follows: Arms, Frankly, Humpty, Coconuts, Davy Sprocket, Skweel, Dynamight, Grounder, Spike, Sir Ffuzzy-Logik, Dragon Breath, Scratch, and Dr. Robotnik.

Chaos Emeralds: There are no Chaos Emeralds in this game.

Miscellaneous: The Game Gear version has four modes of play: Scenario, Gear-to-Gear, Exercise, and Puzzle. Scenario Mode has only one level of difficulty (the Genesis version has four different levels of difficulty) and has 13 levels. Gear-to-Gear Mode is the same as saying "2-player versus mode." This mode only works if both players have a cartridge, Game Gear, and a link cable. Exercise Mode allows the player to practice their skills with the addition of Has Bean and Big Bean. Has Bean was a happy bean until Robotnik turned him into a robot. During Exercise Mode, Has Bean will walk across some of the beans, turning them into the same color. In the higher levels of Exercise Mode, Big Bean will appear. Big Bean is so big that other beans will disappear.

Unlike the version for Genesis, the Game Gear version has a Puzzle Mode. Puzzle Mode is essentially Dr. Robotnik's training manual for robots. There are 30 levels or "lessons" that present a challenge, such as "Eliminate all red beans."
