This really shouldn't be called Tetris HD, rather Grand Canyon Tetris, or maybe Time-wasting Tetris. Tetris HD (or Tetoris) is quite simply a huge resolution, widescreen version of the game we know and love and we warn you now, trying to get even just one line is a mission in itself.

We advise having a look at it, thinking that's a really bad idea and then giving its opposite Alleytris a go instead. Even trying to die in that big open space is pretty impossible. Screenshots below if you manage it!
