Not too much to go into here with regards to this particular iteration of the game we all got addicted to when Game Boy first came out.
This version of Tetris seems to have been a pet project by one of the coders over at Crystal Office.
If you don't know Tetris or have never played the game before on the NES or Game Boy, then why not get your feet wet and take a walk back in time to the days before cell phones?
Either, this is Tetris Free!
