Pet Rescue Saga is a popular mobile game in which players must rescue cute pets by matching two or more squares of the same color to make them disappear and release the pets from their cages. The gameplay is easy to learn, but challenging to master. Players start with a tutorial that explains the basics of the game. The main goal is to clear the board by matching squares, but each level has specific challenges and goals to accomplish. For example, players may need to save a certain number of pets, reach a specific score, or break all the squares on the board. The game is divided into several episodes, each with multiple levels. Each level has a unique layout and objective, and the difficulty increases as the player progresses through the game. To complete a level, players must save all the pets on the board before the action runs out. If they fail to do so, they lose a life and the level must be replayed.

Blocks come in different colors and shapes, and players must strategize to create the best match. Matching two or more blocks creates special blocks that can clear entire rows, columns or groups of blocks. These special blocks can also be combined to create more powerful moves, such as bombs that destroy large areas of blocks or rockets that blow up multiple rows or columns. In addition to the regular blocks, there are a number of obstacles that players must overcome. Some blocks are locked and the player must match them with a key to unlock them. Other blocks are indestructible and cannot be matched, requiring players to bypass them to reach their goal. There are also different types of pets, each with their own special abilities, such as cats that can climb the board and birds that can fly over obstacles.

To make the game even more challenging, Pet Rescue Saga includes power-ups that players can purchase or acquire in the game. These power-ups provide additional moves, boosters, or special abilities that help players complete levels faster and earn higher scores. There are also daily challenges and leaderboards where players can compete against each other for high scores and rewards.
