Brew Brothers Slot RTP, Details & Wager Limits
The Brew Brothers slot has 5 reels, 4 rows and 40 fixed paylines. Simply land 3, 4 or 5 matching symbols from left to right, beginning from the leftmost reel, across any of the paylines to constitute a winning combination.
Bets-wise, you can spin away on Brew Brothers from 20p to £60 a spin. On the desktop version (that’s a laptop or PC), use the plus and/or minus buttons to change your bet accordingly. If you’re playing on a tablet or smartphone, press the ‘Coins’ icon to see a scrolling menu of stake options.
Non-UK players can use Lightning Mode and Autoplay (for up to infinite auto spins). Slotmill offers Burst Mode which is a faster and more focused Autoplay. You select a certain amount of auto spins and your bet and it will display your outcome without the gameplay showing. I found it a little odd truth be told.
The Brew Brothers RTP is 96.09%. Above the average of 96%, this is the only RTP version that Slotmill has created. This means that you’re guaranteed to play with a 96.09% RTP rate at all UK slot sites that offer Slotmill slots.
Very high volatility, Slotmill provides no hit frequency rate information, unfortunately. When it comes to win potential, the Brew Brothers slot offers 12,000 x bet max wins.
Theme: journey into the Wild North with hillbilly siblings
With a beer/hillbilly theme, the Brew Brothers slot game sees you venture deep within the untouched northern woodlands. You join the 2 hillbilly siblings (according to Slotmill) who are busy creating their legendary beer.
With an upbeat, banjo soundtrack, it reminds me instantly of Ugliest Catch (Nolimit City). The graphics/animations are good as there’s a real ‘feel-good’ factor about these whacky brothers.
On the reels, symbols include A, K, Q and J royals. Then you have buckets of water, corn, yeast jars, bags of sugar and the Brew Brothers (Conny and Ray). Ray is the best-paying symbol awarding 1.25, 3.75 or 12.5 x your total bet for 3, 4 or 5 across a payline.
There is a Beer Wild symbol that substitutes for all paying symbols above. It only appears on the 3 middle reels (i.e. reels 2, 3 and/or 4). With Wilds also appearing with a 2x or 3x multiplier, the Wild Multiplier will apply to the winning payline it appears on. If multiple Wild Multipliers are part of a win, the multiplier values are added together and then applied.
Other symbols include the Bonus and Old Betty Wild. More on these symbols below in the Bonus features section. I must say the symbols are high-definition and stand out nicely against the reels/setting.
| Symbol | Payouts/Info |
|---|---|
 J | 3, 4 or 5 = 0.2, 0.4 or 1.4 x bet |
 Q | 3, 4 or 5 = 0.2, 0.4 or 1.4 x bet |
 K | 3, 4 or 5 = 0.2, 0.4 or 1.4 x bet |
 A | 3, 4 or 5 = 0.25, 0.5 or 1.6 x bet |

 Corn | 3, 4 or 5 = 0.4, 0.8 or 2.5 x bet |
 Yeast Jar | 3, 4 or 5 = 0.5, 1 or 3.5 x bet |
 Bag of Sugar | 3, 4 or 5 = 0.75, 1.5 or 5 x bet |
 Conny | 3, 4 or 5 = 1, 3 or 10 x bet |
 Ray | 3, 4 or 5 = 1.25, 3.75 or 12.5 x bet |

Brew Brothers Mobile
Released on the 30th of January 2024, Brew Brothers is compatible with desktop, tablet and mobile devices. Created using HTML5 technology, it looks particularly good on iOS and Android smartphones. For reference, all Slotmill games are mobile-friendly.
Brew Brothers Bonus Features
The Brew Brothers slot has 6 bonus features. Unused Bonus symbols change into wilds and Old Betty Wilds add up to 9 wilds on the reels. If they land on top of another wild, they become multiplier wilds. In the free spins, all wilds are sticky with Old Betty Wilds becoming Gold Betty Wilds which can add more wilds on each free spin. Fill the 3 middle reels with wilds to add a Giant Wild which can benefit from an increasing multiplier.
Bonus Wild feature
When the Beer Bonus symbol lands, on reels 2, 3 and/or 4, and doesn’t trigger the free spins, Bonus symbols convert into single Beer Wild symbols. This is known as the Bonus Wild feature.
Old Betty feature
Look out for the Old Betty Wild symbol that appears on reels 1 and/or 5. Substituting for all paying symbols, the Old Betty Wild pays 1.25, 3.75 or 25 x your total bet for 3, 4 or 5 in combination.
There is a chance that the Old Betty feature will be triggered. If so, the Betty Wild adds 1 to 9 Beer Wild symbols to reels 2, 3 and 4. Furthermore, if a Beer Wild is added to a position containing a Beer Wild, the multiplier of that wild increases by 1. Only 1 Old Betty Wild can be present per reel.
Free Spins Bonus feature
The Free Spins Bonus with Sticky Wilds feature is triggered when you land 3 Bonus symbols anywhere on the reels during a base game spin. 7 free spins are awarded.
To help increase your chances of triggering the free spins, you can use the optional Xtra-Bet feature. For a 2.5 times higher chance of playing the free spins, your stake/bet increases by 50%. The RTP goes down ever so slightly to 96.08%.
During the feature, all Beer Wilds that land on the 3 middle reels are sticky for the duration. No Bonus symbols appear meaning you cannot win additional free spins.
Landing the Old Betty Wild during the triggering of the feature or once it’s started will upgrade the Old Betty Wild into a Gold Betty Wild symbol. These remain in position for the feature and have a chance of activating on every free spin. This can see more Beer Wilds and multipliers added to the 3 middle reels.
Tractor feature
If you manage to fill reels 2, 3 and 4 with Beer Wilds during the feature, the Tractor feature will be triggered. This creates a Giant Wild symbol covering the 3 middle reels. It also counts as a single wild on all positions.
Existing wild multipliers above 1x are also added to the Giant Wild symbol. The wild multiplier applies to each winning combination it’s part of. Now, each extra wild added from a Gold Betty Wild increases the Giant Wild multiplier by 1.
Fast Track feature
The Fast Track feature is for players outside the UK. Essentially a Bonus Buy feature, you have 5 options with the cost and RTP different for each one. It allows direct access to the game’s bonus features. Here are the details:
| Option | Cost | RTP |
| Gold Betty Free Spins (2 Gold Betty Wilds) | 600 x bet | 96.38% |
| Random Gold Betty Free Spins (1 or 2 Gold Betty Wilds) | 300 x bet | 96.29% |
| Free Spins Bonus | 90 x bet | 96.26% |
| Old Betty (1 spin with the Old Betty feature) | 30 x bet | 96.19% |
| 2+ Bonus symbols | 10 x bet | 96.18% |
Brew Brothers Verdict: go on a wild adventure with Ray and Conny
For starters, I need to commend Slotmill. Nolimit City aside, there aren’t many slot providers who produce slots with fun themes. The Brew Brothers slot is based on hillbilly siblings who craft their own beer. It works rather well in my opinion.
In terms of the gameplay, there are nice touches from Slotmill. Bonus symbols not triggering the free spins will transform into wilds (I don’t think I’ve seen that before). Keep an eye out for Old Betty Wilds on the 2 outer reels as these add up to 9 wilds on the 3 middle reels. If a wild lands on top of another wild, a multiplier applies.
In the free spins, all wilds are sticky. Furthermore, Old Betty Wilds will upgrade to Gold Betty Wilds which can add up to 9 wilds on every free spin. Again, this can lead to sticky multiplier wilds.
If you manage to fill the 3 middle reels with wilds, you’ll benefit from a Giant Wild which can also have an increasing multiplier. It’s like the Wild Rabbit in Push Gaming’s Fat Rabbit or the Jumbo Potato Wild in Print Studios’ Royal Potato but with multipliers.
In summary, the Brew Brothers slot is fun, and exciting and offers a new way of landing wilds, sticky wilds and multipliers. With 12,000 x bet max wins, it offers an experience well worthy of a few spins.
