Fish Story 3 is another match-3 puzzle game in the fun and exciting Fish Story series. Along the bottom of the ocean, among seaweed, sponges, sea snakes and turtles, the player matches three or more identical items on boards level by level to complete tasks for a mermaid named Pearl. They typically collect marine lifeforms and items and perform other actions. They receive up to three achievement stars per level and coins.
The player creates powerful tools and receive boosters to help them finish faster, which is important because they receive a limited number of moves. On a board, they can create line and cross blasts and rainbow bombs by matching more than three pieces and creating unique match scenarios. They can also use merge mechanics to pair two special items to create even more powerful ways to remove and collect items. Additionally, on the right side of the board, they receive boosters that allow them to swap or remove pieces to create lines.
Fish Story 3 provides the player with gifts from Pearl and other rewards when they reach specific levels. These freebies usually give them extra coins and boosters. They can then use coins to activate and buy boosters.
