I am not so much of a Tetris freak but for those millions fans who would love to play the game whenever possible, here is a portable version of the game. Now the details are a bit sketchy because they forgot to teach me Korean in school, but because my picture comprehension skills are good, I figured that you needed to hook the game up with the wires to a TV. Now the pink device takes in two wires, one that goes into the TV and the other goes into the blue device. This means that two people can play the game together.
The portable Tetris is for 54,000 Won, which would be $58.
