Dig a destructible mine. Craft the gear. Raid the vaults.
Gemhollow is a hand-painted mining RPG where every block is yours to break. You start with a basic pickaxe and fifteen pockets of carrying space, and you dig — sideways, downward, wherever the ore is — placing your own ladders, ceiling supports and bridging beams to reach seams nobody else can.
Haul what you find back to the surface, sell it on a market whose prices actually move, and turn the money into a better pickaxe, a bigger pack, a brighter lamp. Then go deeper, because the good stuff is always deeper.
Two full worlds, 56 story quests, six hand-built puzzle vaults, pets, robot miners and a contracts board — and the whole thing is free, with rewarded ads that are always optional.
Play Now – It's FreeTwo complete mines, each 500 metres deep, each with its own ores, tools, hazards and economy.
World I
Home base is a sunlit village — Mine Control, the Market, the Item Shop, the Gear Shop — built around the tunnel entrance that drops you into the shaft. Stone gives way to iron, then gold, then diamond, and the rare stuff starts appearing once you're past a hundred metres down.
World II
Through the gate, everything is harder and worth more. Abyssal Rock takes ten times the swings of surface stone, toxic gas pockets bleed your vitality until you've earned a rebreather, and the ores are corrupted mirrors of the ones you knew — Shadow Iron, Void Diamond, Star Sapphire.
Not a feature list — these are the actual systems running in the game right now.
500 rows deep, 50 columns wide, procedurally generated and completely destructible. Tunnel any direction and place ladders, ceiling supports and bridging beams to build your own route down — then fall down your own shaft if you're careless.
Hit ore and you earn the yield. Time the Iron Striker, purify gold, align diamond fissures, hold a harmonic resonance — nail it perfectly for five units instead of one, plus a bonus gem roll.
Hand-built labyrinths, not random rooms. Dodge flame jets, ride wind geysers, survive a gas maze, pick the vault lock — each one guards a Keystone the campaign needs.
Daily, weekly and monthly jobs from the Gemhollow Mining Company that scale with your pickaxe tier. Clear 40 in a month and you keep that month's exclusive aura for good.
Buy them with gems, not cash. A Quartz Dog adds speed and ladders, a Ruby Cat doubles every ore you collect, a Sapphire Bat throws away spare stone so your pack stays useful.
Donate ore to build a fleet of twelve automated units, from a Stone Excavator up to an Aetheric Unit at six times the yield. They keep digging while the app is closed — up to twelve hours on a full power cell.
Ore prices drift, surge and recover in real time — dump too much of one ore and you depress its price, or wait for a demand event and double your money. Add a 30-day login ladder, stacking boosts, 17 auras and 38 Play Games achievements on top.
Real damage values from the game. Each tier is the difference between bouncing off a block and breaking it.
A trusty starting pickaxe.

Quest reward onlyThe Abyss runs its own ladder on top of this one — a Makeshift pickaxe, then Void-Tinged (150), Astral (600) and beyond, each forged from ores that only exist down there. Alongside it: eight backpack tiers from 15 slots to 1,000, four head-torch levels, gas masks, ladder pouches, drill bits and battery packs.

Every one of these has a corrupted Abyss counterpart worth roughly double — Dark Quartz, Blood Ruby, Star Sapphire, Void Core, and Dark Aetherium at $5,000. And the Market moves those prices while you play.
Six of them, each a designed puzzle with its own hazard and its own Keystone at the end.
A pitch-dark procedural labyrinth. You get 99 ladders and 25 beams — the challenge is navigating the maze and solving the gate sequence, not rationing supplies.
Keystone of EarthFifty-two rows of hand-tuned maze threaded with flame-jet emitters and magma rock that detonates when struck. Reach the venting console at the top to shut it down.
Keystone of FireSeventy-five rows straight up. Build platforms over wind geysers, ride the updraft, land the jump — miss and you start the climb again.
Keystone of SkyTwenty ladders, five gas pockets, and a golden chest at the far end. Break the wrong block and the fog comes for you.
Golden ChestA tight bridging puzzle in the deep dark, with a Keystone of Fire waiting at the end of a long horizontal run.
Abyss · World IIFive wind geysers, fifty beams, fifty ladders and a Keystone of Sky. The last vault before the Overworld Interface.
Abyss · World IIA plot of land the Company sets aside for you, early — decorate the grounds, then step inside your house and greenhouse and decorate those too.
The quest Stake Your Claim hands you the plot not far into the surface game — name it, and a free Miner's Cabin is yours to set down wherever you like. Everything after that is bought with Sovereigns, a currency that exists only for the Claim.
You earn Sovereigns by shipping raw ore at the plot's own Shipping Office — no trip to the Market required. It's a second use for the ore piling up in your bag, not a second grind.
Every tree, fence, path and building here is cosmetic — nothing you place changes your mining stats or your progress. It's the one part of Gemhollow that's just for you: your cabin, your garden, your greenhouse, arranged exactly how you want them.
Collect a full set of any category — every fence type, every seat, every plant — and the Company pays out a one-time Sovereigns bonus for the completionists.
Plants are the one thing on the Claim that runs on a real clock — pot one in the Greenhouse and it grows through its stages over 4 to 12 hours of real time, timer or app open or not. Grow one to full bloom and it unlocks for the house too, not just the glasshouse it was raised in.
Cosmetic appearances, not classes — every miner plays identically, so nothing is locked behind a look. Swap them at the Character Market.
Both unlocked from the first launch. Pick one on the character select screen and get digging.
Earned by finishing A Lost Legend. Collect it from the Character Market once the quest closes.
The prize at the end of the 30-day login ladder. Miss a day and the streak skips — no shortcuts.
A rare roll from supply crates. Nobody sells it and no quest grants it — you get lucky, or you don't.
Part of the Founders Pack, at the game's largest visual scale. There's a corrupted Abyss variant too.
The fence with the hideout below the mine. Play as him — if you can work out how he's unlocked.
Plus the Elite Prospector and Mythic Excavator from the token shop, the Rookie Miner kit, Blacksmith and Elite Vanguard as prestige rewards, and Abyss-tinted versions of nearly all of them — 21 in total.
Captured from the live Android build — no mock-ups, no touch-ups.
Grab a pickaxe and find out. Gemhollow is free on Android, and the rewarded ads are always optional.
