Pet Rescue Legend is an entertaining puzzle game created for Mac by Superpow Studio. The app has nice, colorful graphics, provides you with 80 challenging levels, gives you access to plenty of gameplay instructions, and automatically saves your progress.
Each level comes with a certain list of goals. The main objective, which is available in every mission, is to rescue the animals. You can do that by matching tiles of the same color until all animals are at the bottom of the screen. Each time you remove blocks from the board, the rest of the tiles move to the bottom of the window.
You also have access to several power-ups that help you complete missions easier. For example, you can use the Hammer power-up to eliminate one block from the board.
Another advantage is the fact that you can always replay missions if you wish to increase your overall score. However, you cannot play a level until you complete the previous ones.
All in all, I think Pet Rescue Legend is a great game that comes in handy while you're on a break from work. In addition, it comes without a price tag. So, I can't find any reason why you shouldn't try it on your computer if you're into playing this type of games.
