Dr. Robotnik's Mean Bean Machine

Dr Robotnik's Mean Bean Machine is a Tetris-styled SEGA game from November 26,1993. You have to match the beans (4 in a row) to get rid of them.

Scenario Mode
In Scenario Mode you complete the levels throughout a basic story,

2P Mode
This mode is for two players to play together using two sets of buttons on a SEGA device. They are against each other trying to see who wins.

Exercise Mode
Exercise Mode is basically a practice for 1 or two players so you can practice/exercise for the upcoming harder levels.

Combo
A combo is when someone gets multiple beans matched in a row.

Combos win you more points, increasing chances of winning the game. People sometimes record these and put them on YouTube.

Winning & Losing
To win the game you have to last longer than your opponent. You lose by making a row of beans to the top of the screen.

Online game
Now because of the small number of people playing with SEGA devices an online version of the game has been released.
