Ravine Edge

Ravine Edge puts you in charge of a placer gold wash plant cut deep into a mossy ravine. Every shift brings a fresh ore order: placer gold, vein gold or tailings rework, each with its own weight and grade target. Tune three live controls, feed, wash water and sluice slope, to match the highlighted sweet band for the current grain size. Cycle the jig pulse to keep fine gold out of the tailings. When the concentrate band sweeps the shaking table, hit CATCH inside the green window for a richer cut. Sludge can choke the sluice at any moment, so tap clogs out fast before recovery stalls. Periodic assays reveal your concentrate grade, or buy the Online Grade Analyzer to watch it live with a trend curve. Six real upgrades in the Supply Depot, from a variable feeder to a long term smelter contract, all work immediately and stay yours forever. Payout equals recovered gold times grade, with a bonus when the order target is met. Original cartoon art, runtime synthesized sound effects, no ads, no accounts, just gold.
