About the Demo

Dive back into the ocean and relive the game that started it all!

Fiiish! Classic is a lovingly polished re-release of the original underwater adventure from 2010 — now free to play during launch on Steam.

Swim through a vibrant, hand-crafted ocean full of colorful wildlife and hidden surprises. Take your time, relax, and enjoy the peaceful flow of the sea as you collect coins, spend skill points, and upgrade your fish to reach new depths.

No rush. No pressure. Just you, the ocean, and the coins waiting to be found.

🐟 Discounted for a limited time!

To celebrate the return of Fiiish! and to thank our fans, Fiiish! Classic is discounted during its launch period. Grab it now and keep it forever — after the launch celebration, the game will return to its regular, low price.

And for younger players or anyone who wants an even gentler experience, turn on Kids Mode — a safer, calmer way to explore the deep.

Fiiish! Classic — Back to the Deep.
