Tetris just came back with an educational twist. When you couple Tetris with education, you are sure to get someone to learn something, because Tetris is extremely addictive. The object of the game is to put all of the parts of China in its rightful place. A blank outline of China is on the screen and pieces, which happen to be territories, drop in and it is your job to place them in the correct location they belong in. There are three levels of difficulty; each with its set of unique challenges. Use the right and left arrow keys to move the pieces. Use down to speed the territory's descent, and press 'enter' to make the piece drop.
