Moolah Miner Slot by Genii

Most cascade slots from the Genii catalog play it safe with one or two mechanics layered on top of the tumble engine. Moolah Miner is the greedy one of the family. It runs the same engine as Falling Fossils and Winning Waterfall, then piles on a doubled multiplier ladder, retriggering free spins, and a separate pick bonus with one of the most generous selection counts in any cascade slot.

The base game cascade ladder runs x1, x2, x3, x5. Each consecutive winning cascade in the same chain bumps you up one rung, and the multiplier locks at x5 once you reach it until the chain dies out and resets. That part is standard for the engine. What changes things is what happens when scatters land mid-cascade. The Free Falls trigger gets banked into a "Free Falls Total" counter and only fires after the cascade chain finishes paying, so a lucky chain that drops a second set of scatters stacks into a longer bonus instead of cutting the current win short.

Inside Free Falls the multiplier ladder doubles to x2, x4, x6, x10. This is the part that separates Moolah Miner from its siblings. Falling Fossils and Winning Waterfall keep the same base-game ladder during free spins. Here, a single 4-step cascade chain in the bonus is paying at x10 instead of x5, which is a meaningful difference on the hit-rate side because cascade chains in the free round happen often. Three scatters give 10 spins, four give 15, five give 20, and they retrigger - itself rare for Genii.

The Dynamite Pick is the third feature and lives outside Free Falls. Three Feature scatters open a board of 15 dynamite blocks and you pick 10 of them. Not 1, not 3 - ten. Each block reveals a bet-proportional cash prize. The pick bonus cannot trigger from inside Free Falls, which is the one structural limit on stacking everything at once.

Visually it's a prospector saga. The reels sit inside a wooden cabinet planted on the desert floor, with a cactus on the left, a stacked stone wall on the right, and a cartoon old-timer in blue overalls leaning against a red dynamite crate next to the frame. A lantern hangs off the right side of the cabinet. The multiplier ladder is built right into the top of the cabinet itself, lit milestone by milestone as your chain climbs. Symbols lean hard into the theme: silver and amethyst gem ore, a chunky gold nugget, a bundle of red dynamite sticks, black coal lumps, a pickaxe, and royals carved into rough stone tiles tinted by the gem each one is set into - icy J on blue ore, purple Q on amethyst, ruby K, golden A. The Free Falls scatter is hard to miss with its gold border and red lettering.

The math ceiling is the catch. 5,000x is modest by 2026 standards and noticeably below what Falling Fossils and Winning Waterfall reach despite the busier feature set. You are paying for variety here, not for a top-end win.
