Little Stone Museum

Crack open rough stones, cut them into sparkling gems and fill your own cozy museum. Learn real geology from Prof. Augusto along the way, one stone at a time.

Pull on your boots, grab a pick, and come dig with us.

Little Stone Museum is a cozy game about finding rocks, cracking them open and turning the best ones into gems for your very own museum. No rush, no stress. Just you, a tray of rough stones and that little thrill of seeing what's inside.

Meet Gemma, who runs the digs. She keeps finding stones while you play, and even while you're off doing other things. Tap a rock and it pops open. Most of the time it's a pretty piece of agate or jasper. Sometimes it's a sapphire. And every once in a while it's something Legendary, and you'll want to show someone.

At the bench, you decide what each stone becomes. Facet it into a sparkling gem, or polish it smooth into a cabochon. Stop the light right in the center for a clean cut. Land a Master cut and your stone can be worth many times what it was. Some stones keep secrets inside: tiny inclusions, twinned crystals, or silk that turns into a glowing star when you cut it just right.

Then there's Prof. Augusto, the kind old geologist who looks after the museum. Every place you dig has its own hall for him to fill. The pieces you put on display earn coins by the minute, a full hall earns even more, and your favorite stone gets the plinth in the middle.

REAL ROCKS, REAL SCIENCE Every stone in the game is a real mineral, and Prof. Augusto loves to talk about them. Open any specimen card to learn its chemical formula, its crystal system and its hardness on the Mohs scale, how it forms in the Earth, what gives it its color, and where in the world it's found. Each one comes with a curator's note, too: a bit of history or a surprising fact. Why do chemists still grind things in agate bowls? Why did the Romans make their seal rings from carnelian? You'll find out. It's a gentle way to learn real geology, one stone at a time.

A WORD ABOUT ADS You'll never get a pop-up or an ad you didn't ask for. If you'd like a little boost, you can choose to watch a short video. It can add a bonus to what you earned while you were away, light the Lucky lamp for better odds on your next ten finds, or bring one more crate from Prof. Augusto. Each one has a small daily limit.

Rather have no ads at all? The Full Game is a one-time purchase that removes them and gives you the same bonuses in one tap. No subscription, no premium currency, and stones are never for sale.

Make a cup of tea, open a rock or two, and see what turns up. The stones will wait for you.
