Scratch Raw Stone: Gem Master
Buy rough stones, scratch them open to reveal what's inside, and decide whether to cash out or craft rare jewelry.
Developer: Playgama
Play Scratch Raw Stone: Gem Master Online for Free
Scratch Raw Stone: Gem Master builds tension into a genuinely simple loop. Every stone you buy is a gamble — scratch it open slowly and you might reveal rich color worth real money, hairline cracks that tank its value, or nothing at all. The dealer's offering a cash price the whole time you're scratching, so you're constantly weighing whether to lock in a safe payout mid-reveal or push your luck for the full result. Hold out on the best stones and you can cut them into gems, then fit those gems into jewelry templates for bigger profits than a straight sale, slowly growing your workshop from a single scratching table into a real gem business.
How to play
Buy a rough stone, then hold and drag across it to scratch away the surface and reveal what's underneath. Take the dealer's cash offer at any point during the scratch, or keep going for the full result. Save a finished stone to cut it into a gem, then place that gem into a jewelry template — drag to position it, resize and rotate to fit — and complete the piece for a bigger payout than selling the raw stone.
Controls
Click to select, buy, and confirm actions. Hold and drag to scratch a stone open, and to place or resize a gem in a jewelry template.
