Gem Tycoon: Idle Mining Game

Every rock hides a treasure. Crack it open, cut the rough gemstone and find out what you've got!

Gem Tycoon is a relaxing and satisfying idle mining game about cracking rocks and cutting gems. Buy ore, tap to smash it with your hammer, then carve the rough stone with your chisel to reveal its quality. Sell your finest jewels, upgrade your tools and grow from a tiny workbench into a rich gem tycoon – from humble rose quartz all the way to legendary red diamonds.

HOW IT WORKS
• Buy ore – every tier has its own rocks, from granite and marble to kimberlite and meteorites
• Crack the rock – tap to swing the hammer until the stone splits open and a rough gem appears
• Cut the gem – carve the rough with your chisel; when the cutting is done, the grade is revealed
• Sell and grow – sell your gems for coins, level up and unlock the next mine tier

FOUR GRADES, ONE JACKPOT
Each gem is revealed as Flawed, Good, Excellent or the rare Perfect – and if your chisel slips, it can shatter! Sometimes a rock holds a Perfect Rough – a glowing gemstone with your best odds of cutting a Perfect gem worth a fortune. That moment never gets old.

• Your collection displays the best piece of every gem you have ever cut, each on its own velvet cushion

UPGRADE YOUR WORKSHOP
• 12 hammers and 12 chisels, from basic tools to legendary ones – stronger tools crack harder rocks and cut tougher crystals

A FRIENDLY TYCOON ECONOMY
Prices grow with every tier, so there is always a bigger goal: a better hammer, a sharper chisel, the next mining license. Rocks that crumble into gravel are sold off with your gems, and if you ever run short of coins you can still buy the next ore and keep going – you are never stuck.
