Cash Maker Slot by YGR

Cash Maker is the game that started the series. Three main reels, one row, one payline, and then a fourth reel off to the right doing all the interesting work. That fourth reel is where every spin's outcome actually gets decided. It lands on one of five things: a multiplier tile (1x, 2x, 3x, 5x, or 10x), a RESPIN icon, a Silver Wheel, or a Gold Wheel. The three main reels just roll digits in dollar-bill green, and a line hit only pays if three numbers align on the single payline. The real variance lives on reel four.

Multiplier tiles amplify any base hit by their printed tier, capped at 10x. RESPIN is a free reroll of reels 1-3, and the pre-respin and post-respin payouts both count, they get summed, so RESPIN can only add to the pot. The Silver Wheel awards a mid-tier random prize from a visible carnival wheel. The Gold Wheel is the premium path and the thing that makes this specific entry different from its sequels, it's the top-end bonus outcome, richer payouts than the Silver, and it's a CM1 signature. Cash Maker 2 replaced it with a Treasure Vault code-crack mini-game, so if you want the wheel version of the feature, this is the one.

There's also a Lucky Boost toggle at +50% bet, and it's CM1-only, CM2 onward dropped the ante entirely. LB specifically raises the probability of RESPIN symbols landing on the bonus reel and increases the odds of bigger RESPIN-linked payouts. The premium isn't folded into your win math, so line payouts still calculate against the base bet. No Buy Bonus, no scatter, no free spins mode. The entire game is the bonus reel, that's the architecture.

The art leans into US-currency vocabulary, emerald dollar-bill green frames with art-deco scrollwork carved around the reels, flying bills drifting through the corners, and green dollar-sign ornaments separating the main digits. Above the reels a cartoon heist crew lounges on a vault door: a stocky boss in grey suit chewing a cigar, a ski-masked robber, and a woman in pink with a big bow. The crew's gender mix is a CM1 detail, later entries in the series swapped the woman out. A partial multicolored wheel peeks from the upper-right corner on standby. For a series progenitor the feature set is lighter than what Cash Maker 3 eventually piled on, but the Gold Wheel plus LB combination is an identity later installments walked away from.
