How Gold Mine Mystery works
Gold Mine Mystery runs 6 reels with fixed paylines. Stakes in the real-money version run from 0.1 to 40 per spin; the demo uses virtual credits instead. The demo is the same build as the real game, so the feel of the volatility carries across even though nothing is at stake.
