Pool Break (Full and Lite) for BlackBerry PlayBook
One of the only worthwhile Android Apps I've found that's "officially" available via BlackBerry App World is Pool Break, which offers PlayBook owners a visually engaging and fun billiards experience. The free version only offers two types of pool: traditional eight ball and nine ball. But the three-dollar "Pro" version features many different styles of pool and a number of additional gameplay options, making it well worth the cash.
