Dr. Robotnik's Mean Bean Machine

Dr. Robotnik's Mean Bean Machine is a Sonic the Hedgehog video game. The game is a modified version of the Japanese puzzle game Puyo Puyo. Unlike other games in the series, it takes place in the same universe as the Adventures of Sonic the Hedgehog cartoon.
The game is played with two opponents trying to connect as many chains of four or more similarly colored beans as possible in a large grid. As higher chains are achieved, Refugee Beans are sent to the other side. This can only be removed when a neighboring group of beans is matched. The winner is the one whose beans do not reach the top of the grid. There are various modes that allow players to battle each other in various difficulty settings. These determine speed, the initial number of Refugee Beans, and other various things.
