Put that silly smartphone back in your pocket, Tetris fan! The Pebble e-paper watch is now able to do more than just tell you when you've received a new SMS and play Snake -- a new application called "Pebblis" clones the iconic Russian puzzle game for Pebble with stunning accuracy. Even better? It's free, and super easy to get working. All we had to do with our Android was click through the source link and the Pebble app took care of the rest. Apparently it's a bit tougher to get running via iOS, but then again, Pebblis isn't really an "official" application anyway. And yes, playing Tetris on a watch is pretty difficult. Obviously.
