Fishdom | (LS) (Nintendo DS)

Fishdom is a puzzle and aquarium simulation game on the Nintendo DS where players complete match-3 style puzzles to earn currency used for building and decorating virtual fish tanks. The game is structured around alternating between puzzle rounds and aquarium customization, creating a loop where performance in the puzzles directly impacts how quickly new fish, decorations, and upgrades can be unlocked. Each aquarium acts as a separate space that can be gradually filled with themed objects and aquatic life.

Gameplay centers on swapping tiles in a grid to form matches of three or more identical pieces, clearing objectives within a limited number of moves. Successful puzzle completion rewards coins that are spent on fish, plants, and decorative items for the aquarium section. As players progress, puzzles introduce new mechanics and increasing complexity, requiring more planning and fewer random matches.

This game builds its experience by linking puzzle performance directly to visual progression in the aquarium, where each completed board translates into noticeable environmental changes. by tying rewards to customization, it encourages repeated puzzle play as a means of expanding and improving each tank. with its split structure, it balances short, focused puzzle sessions with longer-term creative building. because of that loop, progression feels like gradually designing a living display that reflects how well each puzzle stage is completed.
