How to play Barbarossa DoubleMax mobile slot

The Barbarossa Doublemax slot gives you beautifully designed 5×3 reels where every win explodes and doubles the game multipliers, giving you the potential to win 20,000x your bet.

Barbarossa Doublemax is filled with beautiful designs and animations, from the swaying cannonballs at the bottom to the blinking eyes of the pirates themselves; this is a top-notch Buccaneers slot game.

Barbarossa is the main high-paying symbol, followed by his four shipmates, the low-paying gun, compass, ship wheel, anchor, and a bottle of rum. The two special symbols are the wild and the pirate flag scatter symbol.

The first thing you need to do is turn the Golden Bet on – much like in the Golden Fishtank 2 slot, for 0.25x your bet extra, you double your chances of catching the free spins. And you want the Barbarossa Doublemax slot free spins because the multipliers are sticky.

The big multipliers of the Barbarossa Doublemax slot

The Barbarossa Doublemax mobile slot is a cascading wins slot where the winning symbols explode on every win, leaving behind a wild and the multipliers double.

This increases your chance of catching a further win, which is what you need to get to the top win. The paytable itself is pretty weak without hitting at least over 10x multiplier, maybe more on low-paying symbols.

The good news is that the multipliers do double easily, and randomly the game may even skip ahead 3 multipliers just because it’s feeling generous and kind.

The free spins bonus and those sticky multipliers

What makes this Barbarossa Doublemax online slot special is the bonus games.

Get 3 scatters, and you’ll trigger 7 free spins, where the doubling multipliers do not reset between spins; instead, they keep doubling, allowing you to hit the hundreds.

It’s always exciting to see it happen, and even a little tempting to click the ‘buy slot free spin‘ button on the side, but be careful. The RTP of this Barbarossa slot is a low 94% as standard, 94.2% if you click on the golden bet button.

It’s low because this is a high-variance game with a huge top win of 20,000x your bet. It’s not for the faint of heart and requires a strong constitution.

In-game bonus features

Wild Cascades Multipliers: Every win triggers a cascade - winning symbols explode, and more come tumbling down to replace them. However, a wild symbol is added to one of the winning positions to help create a new win.

Every cascade doubles the total multipliers for all wins. This resets between spins, except in the free spins where the multipliers don't reset.

Multiplier Jump: There's a random chance that the multiplier can jump up one position up to 3 times in a row.

Scatters and Free Spins: 3 scatter symbols trigger 7 free spins, with every additional scatter added +2 free spins. During the free spins, the multipliers do not reset.

Golden Bet: For 0.25x extra per bet, you double your chances of hitting the free spins. The overall RTP of the game goes up to 94.2%.

Buy Bonus: For 100x your bet, you can buy entry into the free spins with 7 free spins. For 200x your bet, you can buy a random free spins bonus - potentially with more than 3 scatters, but not always.

Barbarossa DoubleMax Review Conclusion

The Barbarossa Doublemax slot is for casino players who don't mind having a cutlass right on their necks the whole time they play, hoping to get their hand on this captain's treasure.

And treasure there is, a vast 20,000x your bet if you can get those multipliers into the hundreds in the free spins.

If you can't, this volatile slot may slice your throat, what with that low RTP, so be prepared to fight hard for every doubloon.

This won't be for everyone, but if you come into this addition to our Yggdrasil slots list with open eyes, you'll enjoy a fantastic game with some high-thrill wins.

Give it a spin at one of our top Yggdrasil casinos with Peter&Sons games and see if you can find the big booty hiding within.
