Explore, collect, and build your very own cozy museum! In One Coin Museum, travel across the seas and use your claw to grab hidden treasures. Display your finds to attract visitors, grow your reputation, and upgrade your boat to reach even more distant wonders.
One Coin Museum
SteamSet sail as Toadz, a cute frog who dreams of opening a sea museum with their friend Charlotte. Explore vast oceans to uncover hidden treasures and display them in your museum. Complete your collection, meet new friends who will help you along the way, and see your museum come to life… You might even discover incredible things during your journey.

Sail across wide oceans and explore new areas as you go. The deeper you travel, the more treasures you’ll uncover… and the more there is to discover beneath the waves.
Use your claw to retrieve treasures from the ocean floor. From common finds to rarer pieces, every item you bring up can enrich your collection.
Master your aim, grab what you can, and see what comes up from the depths.

Display your treasures in your museum to attract more visitors. The more complete your collection, the more people will come to see it.
Bring your museum to life, one find at a time.

Hello! Toadzillart here 👋
It’s with great joy that I present my second game, One Coin Museum! After exploring cozy idle gameplay with Whimside, I wanted to return with a slightly bigger adventure.
Inspired by the sense of discovery from the games of my childhood and my unconditional love for collecting, I hope this little project brings you as much joy as I had creating it.
A special thanks to Tadpoly for all the support, both with marketing and on a personal level 💚
