About this game

Park Foundation & Growth

Starting with a single tank and a few fish, you gradually build a larger aquatic environment. The idle system ensures your park continues to earn income even when you are not actively playing, making it suitable for players who prefer a low-pressure experience. Each new tank or species you add increases visitor interest and revenue, creating a steady cycle of expansion.

Marine Life Care & Happiness

Keeping your fish healthy is the core of park management. Regular feeding and clean water maintenance are essential. Happy marine life attracts more visitors, which directly boosts your income. The game does not impose strict deadlines, allowing you to tend to your creatures at your own pace.

Unlocking New Species & Attractions

As your park grows, you can introduce new marine species such as playful otters and larger predators. Each addition brings a fresh visual element and attracts different types of visitors. Unlocking these requires accumulated revenue, encouraging strategic upgrades over time.

Layout & Visitor Flow

Arranging tanks and attractions to optimize visitor movement is a key part of the gameplay. You can experiment with different layouts to see which configurations draw the most guests. The simple mouse-based controls make rearranging straightforward, and you can zoom in for a close look at your fish or zoom out to view the entire park.

Passive Income & Upgrades

Idle mechanics mean your park generates income automatically, even when you are offline. Investing in facility upgrades that boost passive earnings is a smart strategy. This allows you to progress without needing constant attention, making the game ideal for busy schedules or casual play sessions.
