Acid Rain for the BlackBerry PlayBook is a simple yet fun swiping style of game. Your job is to protect your three flowers from the storm that will produce some nasty acid rain. In order to do this you must swipe away the evil green acid rain. Using combinations will earn you more points but it isn't quite that easy. As the levels progress you will find more and more blue rain drops. These are good for your plants so you need to avoid swiping those, which when in a swiping frenzy can get a little challenging.
There will also be bonus drops & power-ups to help boost your score and keep your flowers alive but let the acid rain fall on your flowers and they will die.
While the game is not the most exciting, it is smooth and chilled out, with fluid graphics. Is it worthy of its $0.99 price tag? I would say it is.
