A simulation game covering the entire process of jadeite processing. All steps from raw stone selection to finished product are operated by the player.

• Drill Excavation: Start by manually mining ordinary stone with hand‑held tools. Unlock drills to enable automated extraction, gaining access to jadeite rough stones from various mining sites.

• Cutting: Control the machine to cut the stone. Avoid cracks to maximize the usable material and value.

• Windowing: Shine a flashlight on the rough stone to carefully inspect its internal water quality, color, and hidden cracks. When cutting to create windows, avoid fissures and poor‑texture zones. Judging stone quality relies entirely on experience.

• Authenticity Check: Learn to distinguish natural jadeite from artificially treated fakes. Study flaws and understand how cracks and cotton‑like inclusions affect pricing.

• Progression: Sell finished products to accumulate funds. Upgrade equipment and purchase higher-grade raw stones.
