About

Eight gems sit on the mine wall at once, each with a color and a purity number, and connecting same-color gems into a vein sets off a blast that scales with how pure that vein was. You dig through eight increasingly rich layers, stopping at supply stations between them to pick run-specific gear — bonus points on a color, doubled blasts, a supercharged finisher — so no two runs play out the same. Each layer's boss anomaly seals off a color or eats a blast outright, forcing you to actually adapt instead of repeating your best combo forever.

Controls

Drag across matching gems to link them into a vein, then release to blast.

Tips

• Chase purity over vein length — a short chain of high-purity gems will out-score a long chain of mixed junk almost every time.
• Read what a layer's boss anomaly restricts before committing to a vein; wasting a blast on a sealed color costs you the whole turn.
