Federico Viticci wrote a nice review of SketchParty TV, a Pictionary-like game that uses the iPad and Apple TV via AirPlay Mirroring:
We ended up playing SketchParty TV until 6 AM. At one point, I was laughing so hard at my friend’s attempt to guess a platypus (I’m terrible at drawing) that I dropped wine all over my elegant New Year’s Eve outfit (I’m also terrible at laughing without causing things to fall off desks and/or tables).
It’s a very well done game. You break people up into two teams, and then one team member (attempts) to illustrate a word they’re given so their group can guess it. The team member draws on the iPad and can see the word, while everyone else sees what they’re drawing on the TV but cannot see the word. I bought it for a little party a few months ago, and everyone absolutely loved it. It’s a lot of fun.
It’s also a very good use of iOS’s AirPlay Mirroring feature. There’s a ton of untapped potential here for party games of this sort—one I can imagine is Taboo, where the person trying to give hints to their team has the list of “cards” on their iPhone, iPad or iPod Touch, and each team’s score is shown on the TV screen.
In any case, I highly suggest checking out SketchParty TV. It’s a great game.
