Pet Rescue Saga Online is a match-three puzzle game from the makers of Candy Crush Saga. Although it shares some element with Candy Crush, Pet Rescue is based on matching falling blocks; the goal is to eliminate matching blocks to help the pets stranded throughout the screen fall to the bottom and escape. The cute animals make the game visually appealing, and the game play, although derivative, is fun enough to be addictive. Like most games of its type, this one relies heavily on in-app purchases.
