Brew Brothers

Our recorded Brew Brothers bonus

We have opened Brew Brothers once on 24 Jun 2026 on stream and logged the result. The best of them paid 12× the bet. That is too few open to say anything about how the game behaves — it is a record of what happened on that occasion, nothing more.

Slotmill sends players to a backwoods, banjo-scored setting for Brew Brothers, a 5-reel, 4-row slot paying across 40 fixed lines at a self-described 'very high' volatility rating. Stakes range from 0.20 to 60 per spin, and the standard RTP is 96.09%; switching on the Xtra-Bet option raises the stake by half and makes the free spins round 2.5 times more likely to appear, at the cost of dropping the RTP slightly to 96.08%.

J through Ace card ranks fill the low end of the paytable, paying 1.4x to 1.6x the stake for a full run of five, while a water bucket, corn, a jar of yeast, a sack of sugar and two character symbols sit at the top, worth 2.25x to 12.5x for the same length. A wild lands only on the three middle reels, substitutes for every regular symbol, and can carry a 2x or 3x multiplier that applies to whichever betline it's part of — if more than one multiplier wild contributes to the same line, their values are added together.

Scatters can land on reels 2, 3 and 4; any that don't trigger the bonus round instead convert into single wilds once the spin resolves. A second wild, Old Betty, appears only on the leftmost and rightmost reels and substitutes for everything except scatters. When Old Betty activates, it seeds one to nine extra wilds across reels 2 through 4, and any of those that land on a position already holding a wild bump that wild's multiplier up by one; only one Old Betty can occupy a reel at a time, and a full line of five wilds pays 25x outright.

Three scatters award 7 free spins, during which every wild landing on reels 2, 3 or 4 sticks in place for the rest of the round rather than clearing between spins — though with no scatters appearing during the feature, it can't be retriggered. An Old Betty that lands, or that was already sticky when the round began, upgrades into a Gold Betty, which stays in place and gets a fresh chance to activate on every remaining spin. If reels 2, 3 and 4 ever fill completely with wilds during the round, the Tractor Feature fires, merging them into a single Giant Wild that spans all three reels and inherits the combined value of any multipliers already above 1x, with each additional wild contributed by a Gold Betty adding a further +1.

Outside the reels, a Fast Track menu sells direct entry into several of these outcomes: Gold Betty Free Spins for 600x the stake at 96.38% RTP, a version with just one guaranteed Gold Betty for 300x at 96.29%, plain Free Spins for 90x at 96.26%, an Old Betty trigger for 30x at 96.19%, or simply two-plus scatters landing for 10x at 96.18%. A separate Burst Mode lets players pick a stake and a fixed number of spins to run through as a single batch. The maximum win across all of this is capped at 12,000x the stake.
