Barbarossa DoubleMax Online Slot Review

Pirates roam the 5 reels and 3 rows of the Barbarossa DoubleMax online slot. It’s a desktop and mobile game with 243 ways to win, and comes from the studios of Peter and Sons, in partnership with Yggdrasil.

The pirates reward features such as cascades on every win, with a wild guaranteed on each, plus the exciting DoubleMaz mechanism that multiplies successive wins over a series of cascades. A Multiplier Jump feature increases the value further, and multipliers don’t reset over the course of a free spins bonus round.

The return to players percentage of this high volatility game is 96.00%, and you can unleash the pirates at the best Pennsylvania slots sites and New Jersey slots sites to plunder wins of up to 20,000x your stake.

How to Play the Barbarossa DoubleMax Slot

Cannon, palm trees, and a skull-shaped mountain are in view behind the wood-framed 5x3 symbol grid. Look to the reels and you find 2 groups of symbols, with lower values ones such as pistols, a ships’ wheel, and compass joined by 5 higher paying members of the motley crew. The characters are quite detailed, and include Captain Barbarossa himself, whose huge red beard helps him stand out. The movie-style soundtrack is just what you would want to hear from a pirate-themed game.

It's compatible with desktop devices and you can play the Barbarossa DoubleMax slot machine on Android, iOS, or Windows mobile platforms on our recommended Betting Apps. There are 16 staking levels, ranging from 0.20 to 50.00 per spin, with a tap on the wager indicator revealing the choices. A Golden Bet costs 50% on top but doubles the odds that you enter the free spins bonus feature. Players can skip the base games entirely and trigger 7 free games for 100x, or a random number for 200x the wager.

Other options include autoplay, triggered via the circular arrows below the reels, and a quick spin mode that starts with a click on the lightning bolt next to it.

You should take a little time to read the Barbarossa DoubleMax slot paytable, as there are some unusual features here, such as increasing multipliers. It’s under the 3 lines on the controls, and there’s also a complete list of how much each symbol pays when enough of the same kind land on adjacent reels, from the left, on any rows. Barbarossa heads the table and depending on how many reels he’s on, he pays 0.5x, 0.8x, and 1x the stake.

Free Spins & Other Features of the Barbarossa DoubleMax Slot Machine

The gold coin wild symbol helps to complete wins by standing in for others whenever possible, although it doesn’t pay anything on its own.

Any win triggers a Wild Cascade, which removes the winning symbols and allows the ones above to drop down. Brand-new symbols appear from the top and cascades run until there are no winning combinations in view.

Cannonballs under the reels hold DoubleMax multipliers running from 2x, to 4x, 8x, 16x, and so on, doubling each time. These apply to each successive win a series of cascades, and feed into a cannon to the side of the reels, which fires a wild symbol onto the grid on each. A random Multiplier Jump moves the values up one extra position and this can happen up to 3 times in a row. The DoubleMax multiplier only resets on a losing cascade.

Three jolly roger flags in any places will launch 7 free spins, with 2 extra games for every scatter above this. The big difference from the base games is that multipliers don’t reset at the end of any Wild Cascades and keep increasing on the following spins.

Barbarossa DoubleMax Slot Maximum Wins, Average Returns, & Volatility

Where there’s no defined limit on the multipliers, in practice the maximum win is 20,000x the stake.

This is a high volatility game, and the return to players percentage, as a long-term calculation, is 96.00%.

Our Barbarossa DoubleMax Slot Rating

The semi-real graphics are quite a departure from the cartoon style used in other Peter and Sons slots, but Barbarossa DoubleMax is a good-looking game and it’s packed to the top deck with extras.

Wild Cascades with an ever-increasing multiplier can potentially lead to a 20,000x win, although you will need a long sequence to reach this level. It gets a little easier via the free spins where multipliers only ever go up, particularly if enough flag scatter symbols trigger enough bonus games.
