Everyone knows i'm a fanatic for Tetris. I don't know what it is but those crazy vodka drinking, awkward-shaped-building dwelling Russians made an incredibly addictive 8 bit video game back in 1984.
25 years later, someone went and flipped the script. No, literally. They went and flipped the screen instead of the individual pieces. Doesn't make sense? Yeah, it's not supposed to. Just follow the link.
Don't worry, you'll only play it for about 2 minutes until you get sick and throw up. But hey, at least you'll be able to say you attempted it.
