I come from Tetris, Dr. Mario, and Panel de Pon puzzle games. This game is basically Dr. Robotnik's Mean Bean Machine from SEGA Genesis, but this is on Super Nintendo. I personally prefer the SNES over SEGA for a number of reasons, but this is basically the same game. This game is incredibly popular in Japan seeing as how over 20 different versions were made.
The game is basically a falling puzzle piece game where 2 jellybeans are attached to each other, can be red, blue, green, yellow, orange, or purple. The gray ones are like the garbage blocks from Tetris Attack. Make 4 beans touch each other and then you clear them and all surrounding garbage blocks. The game is incredibly simple to figure out, but takes a long time to master its combo system.
