Dr. Robotnik's Mean Bean Machine, also known as Dr. Robotnik and His Mean Bean Machine in some European countries, is a falling-block puzzle video game in the series developed by and published by Compile for the Sega Mega Drive/Genesis. Released in North America and Europe during the late 1993, the game is based on the Japanese puzzle game Puyo Puyo. Dr. Robotnik's Mean Bean Machine is also one of the few spin-off games in the Sonic franchise to take place in the Adventures of Sonic the Hedgehog cartoon universe, which aired during the game's release.
The core gameplay of Dr. Robotnik's Mean Bean Machine is derived from the Japanese Mega Drive port of the original Puyo Puyo arcade game, but with altered visuals and rearranged music tracks. Here, the player takes the role of Has Bean, whose mission is to rescue the kidnapped citizens of Beanville and defeat Dr. Ivo Robotnik. Dr. Robotnik's Mean Bean Machine later received a separate 8-bit version for the Sega Game Gear in 1993 and Master System in 1994, which featured similar gameplay and additional modes. The game has also appeared in some compilations and was re-released on the Wii's Virtual Console and Steam.
