First-person Tetris with a side of vertigo
Tetris is one of those games that are iterated on repeatedly. The game has been release on 50 platforms, in 50 languages, and has been played in 185 countries (Tetris.com). Yet somehow, there are people who still have managed to re-invent the game into something crazy and new, which will also have your head spinning. The game is played in a browser and is completely free.
FirstPersonTetris has you sitting in front of old 20-inch Toshiba and playing Tetris on your NES. Everything seems normal until you go to rotate a Tetrimino and the screen starts to rotate as well. Quickly FPT becomes a dizzying experience that retains the addictiveness of classic Tetris. If that still isn't bizarre enough, try turning on Night Mode or Existential Crisis Mode and you will certainly begin to lose your mind. The genius behind this appears to be David Kraftsow of DontSave.com.
