In Pet Rescue Saga you have to rescue cute pets trapped between colored blocks. Solve puzzles to remove all blocks that are necessary to free the animals and gain enough points to win a level. Blocks can be removed by clicking/tapping on at least two adjacent blocks of the same color. Free all pets an gain enough points before running out of moves or before no more blocks can be removed.
Every time you fail completing a level in Pet Rescue Saga you lose a life, but every 5 minutes your lives refill by 1. If you don't have any lives left, you either have to wait, ask some of your friends to send you a life or buy new lives with Gold Bars - the premium currency. There are different boosters that you can use to solve even the hardest levels. Available boosters are for example the Column Blaster Rocket which can remove a vertical row of blocks or Mesh Masher to remove all wire boxes which otherwise prevent that blocks can be removed.
Besides asking your friends for additional lives, you have the possibility to compare your progress and all your level scores to the scores of your friends.
