About this game

💎 Build a cozy gem factory deep underground and watch it work! Little workers dig rough stones out of the rock, then wash, saw, polish and pack them on visible conveyor belts, and every finished gem is sold for coins. You never have to tap to keep it running: you only decide what to upgrade or unlock next.

⚙️ HOW IT PLAYS
• Five machines per mine: mine face, wash drum, stone saw, lap tower and packing bench, each with its own worker
• You see what happens to the stone: water splashes, the saw blade spins, the polishing arm presses, the lid closes the crate
• The slowest machine holds back the whole chain. A sign shows the upgrade that pays most right now, and you decide
• Upgrade by 1, by 10 or as much as you can afford. Milestones give a permanent speed bonus
• At levels 1, 25, 100 and 250 a machine rebuilds itself bigger and finer: wood, copper, brass, crystal
• The more your mine produces, the fuller its belts get

⛏️ SEVEN MINES, SEVEN PLACES
Rootdeep Grotto, Slate Hollow, Dripstone Halls, Geode Hollow, Tidewater Caves, Basalt Steps and Starlit Vault: every mine has its own cave, its own gem and its own rich vein. Sealed tunnels make the cave grow sideways, and at the end the way to the next mine is already glowing.

🤝 REGULAR CUSTOMERS AND ORDERS
• Seven regular customers with their own portrait and specialty order gems
• The mine delivers by itself, even offline. Orders never expire
• Now and then you choose: quick, lucrative, or a favor that builds your renown
• Optional: a video doubles an order reward

⭐ RENOWN
Every delivery raises your renown: up to five stars per mine, a small permanent income bonus, and your customers show up in the cave, from their portrait on the banner to a visit with the merchant cart.

✨ FINDS AND GOALS
While you play, finds appear in the world: a rich vein in the rock, a merchant cart, a sparkling stone. Tapping pays, ignoring costs nothing. About 30 goals give shards, and special goals decorate your cave with a trophy shelf, master lanterns, a chandelier and more.

🔁 NEW START WITH A BONUS
Start over when it pays. The card compares with your last run and shows how much faster the next one will be. You keep a permanent multiplier, your renown, reached goals and shards, and every run adds a crystal to your trophy shelf.

🌙 OFFLINE EARNINGS
Close the game and the crew keeps working: up to 8 hours of income at half speed.

🎁 FAIR AND RELAXED
• Rewarded videos are always optional. No banners, no interstitials
• No in-app purchases, no account needed, your progress stays on your device
• Music, sound and reminders can be switched off separately
• Five languages: English, German, French, Spanish, Russian

Sit back and let your tiny factory sparkle! 💎
Cozy idle gem factory: dig, cut, polish and sell gems, even while you are away.
