Coinboy Riches Slot by Amigo Gaming

An animated train rolls across the top of the screen, red cargo cars stamped with dollar signs trailing behind a little locomotive. That train is the Pile Feature - a symbol collection system that runs constantly during the base game. Dynamite symbols landing on the reels feed into the collector, and once enough pile up, the game randomly fires off one of two bonus rounds: Pin Win or Pick Game. You don't choose which one you get.

Pin Win is a hold-and-win round. Five cash symbols drop onto the grid to start, and respins roll in from there - each new cash symbol resets the counter. Jackpot badges hide inside some of the cash positions: Max at 300x and Mid at 100x. Three progressive jackpots (Grand, Major, Minor) also run in the background, though trigger conditions aren't published. The Pick Game works differently - bags to pick from, a 3-to-win counter tracking your progress, and prize tiers going up to Ultra at 500x and Max at 200x. For a 1400x cap, those pick game numbers eat a sizable chunk of the ceiling. Western-themed slots don't usually split their bonus structure this many ways, and the randomized trigger from the Pile Feature means you can't aim for one over the other.

Free games trigger off three dynamite scatters and come in two modes. One adds wild multipliers to every spin. The other uses expanding symbols that stretch to fill reels on wins. Neither mode retriggerable, so what you get at the start is what you work with. A buy bonus option exists if the scatters aren't cooperating.

Bright cartoon art throughout - a sheriff penguin in a tiny black hat, a cowboy cat riding what looks like a llama along the train tracks, a grinning green cactus with eyes, a red-haired girl. Card values (K, Q, J, 10, A) are chunky and multicolored against dark blue reel strips. The wild is a rainbow-maned unicorn on reels 2 through 5. Sandy desert stretches out behind everything, blue sky and distant cacti, with the metallic rivet-studded reel border giving the whole thing a slightly industrial edge against all that cartoon softness.
