Pet Rescue Saga is a puzzle game in which players have to break apart sets of blocks with the goal of clearing each of the levels while also rescuing the animals trapped on them.
The game has over a hundred levels, each of which presents the challenge of breaking up sequences of colored blocks. Doing so is as easy as scrolling over a group of blocks of the same color.
The goal is to get each of the animals on top of the blocks down to the ground. Doing so will earn you extra points, giving you access to the three stars available in each level.
Due to the social nature of the game you can also compete against your friends. Every time they post a new score it's up to you to try and beat it!
