When I first got my 64, I decided to buy this game since it was fairly cheap. I wasn't a big fan of Tetris but, My brother is so I bought it for him. Instead I ended up playing it. This time you blow up blocks in a sphere that corresponds to the same shape of the block. This is like 50% different comparing to the original tetris. This game is very fun but it gets boring after like a month or if you get a another game but still this game is recommended.
