Crystal Cascade

Work a vivid mineral vein deep inside a basalt cavern. Tap neighboring minerals or drag one into an adjacent cell to make a line of three or more. Matched ore breaks free, minerals drop into the gaps, and fresh specimens can set off another cascade. A swap that makes no match leaves your move allowance untouched.

Each of eighteen deterministic seams requests a particular mineral seal. Collect raw pyrite, ruby, malachite, sapphire, fluorite or carnelian on the six-by-six vein. At the assay bench, choose a tray and let the cutting wheel refine three raw ore into one cut gem. Visit the seal vault, select your refined specimen, and place it into the matching socket to certify the seam.

Ten moves keep each vein compact. If you run out, you can still refine collected ore and finish a seal, or retry the vein. Earned certifications remain saved when you retry or move onward. Pause whenever you need a break; returning to a saved round restores it paused with its legal moves and stock intact.

Crystal Cascade plays offline, with no ads, purchases or account. Distinct mineral silhouettes, chiseled stone surfaces and animated swaps, fragments, drops and cutting make every stage of the ore-to-seal journey visible.
