Barbarossa DoubleMax RTP, Details & Wager Limits
The Barbarossa DoubleMax slot takes place on 5 reels, 3 rows, and offers 243 ways to win. To create a win, simply land 3 or more matching symbols on consecutive reels from left to right.
You can play the Barbarossa DoubleMax slot from 20p up to £50 per spin. This limited range may seem disappointing if you’re a high roller, but we’re quite sure the volatility of the game will keep things exciting. You can adjust your stake by clicking the bet amount under the reels. Here you can choose from 16 preset values.
Outside of the UK, there’s an Auto Spin feature available. This is below the main spin button. With the Auto Spin function you can play an infinite amount of spins without clicking. Do note, however, that you can’t set win/loss limits, so make sure to keep an eye on your bankroll. You can also enable Turbo mode for faster spins.
Barbarossa DoubleMax has an RTP rate of 96.2%, which is slightly above average for online slots. It also comes with a healthy hit frequency of 26.51%, and a high volatility. As such, it has a big win potential though you can spin for a while without landing anything worthwhile.
The slot offers max wins of 20,000 x bet, which is generous for Peter & Sons slots. To reach heights like this, you need to trigger the DoubleMax multiplier feature, which we’ll talk more about later.
Theme – set sail with the Mediterranean’s most famous pirate
If you’re familiar with the Pirates of the Caribbean movies, or 16th century European history for that matter, then the name Barbarossa might mean something to you. For the uninitiated, Hayreddin Barbarossa was once the most feared pirate in the Mediterranean, named after his infamous ginger beard (Barbarossa means Redbeard in Italian). So, naturally, this slot is all about pirates, sailing the high seas, and claiming treasure.
The graphics are amazing, and the soundtrack is suitably tense and rousing. The reels hang against a shipwrecked background and lower paying symbols include all the things a pirate may need; rum, compasses, pistols, and anchors. On the higher end of the paytable you meet your crew, a bunch of gnarly looking pirates with tattoos and scowls.
Barbarossa himself is the slot’s highest paying symbol, rewarding you with 10 x your stake for a 5 of a kind combination. You can also expect to see gold coin wild symbols, which substitute for all others, and Jolly Rodger scatter symbols, which trigger the free spins round.

Barbarossa DoubleMax mobile
Powered by HTML5 technology, you can play the Barbarossa DoubleMax slot on all devices, including mobile, laptop, PC and tablet. The game looks great whichever way you play.
Barbarossa Bonus Features
The Barbarossa DoubleMax slot comes complete with 4 main bonus features, plus an Ante Bet option and a Bonus Buy option. Features include free spins, wild cascades, unlimited multipliers and multiplier jumps.
Wild Cascade Feature
When you land a win in the base game, the Wild Cascade feature is triggered. All winning symbols are removed from the reels, allowing new ones to drop in from above. This is a very common feature in many of the best slots, but this slot gives it a wild twist.
Instead of filling the positions with just normal symbols, a wild is always added to one of the winning positions. After that, regular symbols fill the remaining gaps. Wild cascades continue until no new wins are formed.
DoubleMax Multiplier Feature
Below the reels, you’ll see a string of cannon balls. These represent your multiplier meter. For each win you create, the multiplier doubles. Multipliers start at 1x, so your first win takes this up to 2x, then 4x, and so on.
Multipliers can double unlimited times, but they do reset after a losing spin or cascade.
Multiplier Jump Feature
On any spin, there is a chance that the multiplier meter can jump by one position. So, for example, if you were at the start on 1x, it could skip 2x and go straight to 4x. This can happen up to 3 times in a row.
Free Spins Feature
The free spins feature is triggered when you land 3 or more scatter symbols anywhere on the reels. Landing 3 scatters award 7 free spins, landing 4 scatters awards 10 free spins, and landing 5 Scatters awards 13 Free Spins.
Free Spins cannot be retriggered, and there’s no option to add to your free spins by landing more symbols.
Golden Bet Feature
You can pay an extra 0.5 x bet (so a £1 bet becomes £2.5) to double your chances of hitting Free Spins. This means that a £1 bet, for instance, would cost £1.50.
Bonus Buy Feature
Outside of the UK you also have a bonus buy option. This costs 100 x your stake and gives you immediate entry into the Free Spins feature with at least 7 free spins.
Barbarossa DoubleMax Summary – Tamer than the name makes out
As we mentioned earlier, historically Barbarossa was one of the most feared Pirates of his time. We expected, therefore, that this game would be full of action, looting and more. Unfortunately, that wasn’t the case.
Whilst the Barbarossa DoubleMax slot looks great and offers some interesting features, we found it was hard to claim any big wins. As the game is highly volatile, the multiplier meter can fail to move at all for quite a while. Given this is your best chance at reaching anything near those 20,000 x max wins, we were a little disappointed.
That said, Barbarossa DoubleMax does have moments of genius too. The Wild Cascades feature puts a nice twist on the regular cascading wins mechanism we see all the time. The Free Spins feature can also be lucrative as the multiplier doesn’t reset, though we would have liked more chances to up our free spins count.
Overall, the Barbarossa DoubleMax slot will appeal if you’re a fan of high volatility games with great graphics. The RTP and hit frequency rates are also higher than average, so there is something to play for. Check out how this slot compares to other DoubleMax titles below:
| Slot | Max Win | RTP | Hit Frequency |

| Raptor DoubleMax | 20,000 x bet | 96.01% | 30.5% |
| Neon Villains DoubleMax | 25,000 x bet | 96% | 20.8% |
| Christmas Plaza DoubleMax | 19,978 x bet | 96% | 29.5% |
