GEM WORKSHOP

Roll the dice. Polish your stones. Know when to stop.

Gem Workshop is a compact risk-and-reward dice game about turning rough stones into valuable gems—without shattering them in the process.

Every stone begins with a Target number representing its remaining roughness. Roll two dice and their total is subtracted from every active stone.

The closer a stone gets to zero, the more valuable it becomes. But greed has consequences.

HOW TO PLAY

• Roll & Polish to reduce the Target of every active stone.
• Sell early to secure a smaller profit.
• Reach exactly 0 to create a Perfect Cut and earn the biggest reward.
• Go below 0 and the stone shatters, earning you nothing.
• Spend your profits on additional polishing stations.
• Unlock increasingly valuable types of gemstones.

One roll can improve your entire workshop—or destroy several promising stones at once.

How close to perfection are you willing to push?
