Diamond in the Rough

One legendary diamond is hidden in a mountain of 100 million rocks. Dig, sort, upgrade and chase rare gems until it turns up. How long will it take you?

Somewhere in a mountain of 100 million ordinary rocks sits one legendary diamond. Your job is to find it.

DIG, SORT, GET PAID Hold to fill your bucket, tip it onto the sorting table and inspect every rock. Ordinary stones pay a coin or two. Quartz, amethyst, garnet, gold, topaz and aquamarine pay much more. When a batch is done, watch the whole haul shower into your coin pile.

UPGRADE EVERYTHING Swap your bucket for a wheelbarrow, a dump truck and eventually a mountain silo. Speed up the sorting table. Hire an apprentice, then build conveyors, crushers, sorters and scanners that keep working while you're away.

CHASE THE RARE ONES Sapphires, rubies, emeralds, alexandrite, black opal and painite are rare, and each one powers up a different part of your mine. Every new discovery gets its own big reveal.

THE LEGENDARY Your odds start at 1 in 100,000,000 and improve with every rock you search. The diamond only turns up while you're playing, so you'll be there when it happens.

THEN DIG DEEPER Finding the legendary earns Diamond Dust. Spend it on permanent perks, then set off for new deposits like the Amethyst Caverns, each with its own legendary to find.

FAIR TO PLAY • No account or login needed • Play at your own pace; machines keep digging while you're away • Every purchase is a one-off, kept forever, with no subscriptions • Nothing in the shop can find or improve the odds of a legendary • Optional ads, which you can remove
