About this game

Turn a single rocky conveyor into a roaring ore-crushing machine in Gem Grinder, a satisfying idle mining tycoon where your mine keeps earning for you!

Ore chunks slide down the conveyor, straight into the path of a spiked grinder. Big rocks crack into smaller pieces with every hit, gold pops up with every break, and your income keeps climbing. Your job is simple: invest your gold in the right place and watch your mine grow bigger, faster and richer.

Every lane is part of your growing mining empire:

• Watch the grinder crush ore lane after lane
• Break big rocks into smaller, valuable pieces
• Mine slate, copper ore and rare shiny minerals
• Upgrade each lane to boost your gold income
• Hit level milestones for big earning jumps
• Build and unlock new mining lanes
• Complete quests to earn gold and gems
• Hire Foremen to keep your lanes running, even while you're away
• Unlock powerful Global Upgrades for your whole mine

Start with one lane, earn your first gold and unlock your second lane as your Grind Level rises. Push your upgrades higher, chase massive milestone bonuses and save up for the third lane to multiply your production. Every upgrade makes the grinder hit harder, and every new lane turns small coins into millions.

Finish a mine and move on to a brand-new one, from Crystal Quarry to Magma Depths and Frost Hollow and start the climb all over again with your gems in your pocket.

Gem Grinder is made for anyone who loves idle tycoon and mining games, satisfying crushing and grinding, relaxing one-screen gameplay and watching numbers grow bigger and bigger.

Your goal is simple: crush, collect, upgrade, expand.

Complete quests, raise your Grind Level, unlock new lanes and build the most powerful ore-crushing mine ever. Every rock you break brings more gold, and every upgrade brings you closer to becoming the ultimate mining tycoon.

Can you build the richest mine underground?
