Sketch W Friends for BlackBerry PlayBook has just been updated to v4! Sketch W Friends brings a fresh twist to the good old games of Pictionary & Charades. It is a real-time, multi-player, virtual game where your artistic, creative and vocabulary skills are put to the ultimate test. You get to join a “game room” and compete with players from all over the world- even ones you’ve never met before! You can draw something while others guess what you sketch and vice-versa. All you need to do is call upon your wits and your doodling skills and its game on!
I didn't find any notes on a changelog, but this new version is 1mb larger than the previous one, so I'm guessing there are some significant improvements. If you happen to notice what's new, let us know in the comments below!
