Barbarossa DoubleMax Features

The beauty of any cascading reel system is that a base game takes on an extra level of excitement for the duration of your adventure. And when it comes to DoubleMax, that excitement is cranked up a notch or two. Let's take a look at how this works as well as how you can get your hands on some free spins too.

Wild Cascades

Wild Cascades are like cascading reels but better. Every time you land a win, the winning symbols are removed and replaced with new ones. So far so good, now here's the good bit. One of the symbols that appears after a cascade will be a wild and this could well help to continue the sequence of events.

DoubleMax & Multiplier Jump

Every win receives a multiplier and it all starts at x1. If you land another win during the cascade, then the cannonballs move across and the multiplier is doubled. In theory, this can continue to an unlimited amount. Big wins could be found during the base game thanks to this neat addition that was created by Yggdrasil. 

Hold on, there's more! Every so often, the Multiplier Jump feature can randomly trigger making multiplier values jump to a higher number in the line. This will ensure that wins grow faster and bigger. This can happen 3 times in a row.

Free Spins

To land 7, 10 or 13 free spins, you'll either need 3, 4 or 5 scatter symbols to land or make a direct purchase to trigger the game—remember that the bonus buy won't be available in the UK. 

During the free spins bonus, the DoubleMax feature continues but it doesn't reset between winning cascades as it does during the base game. You could soon see wins multiplied hundreds if not thousands of times thanks to this upgrade.

Barbarossa DoubleMax Review

Barbarossa used to be the most feared pirate in the Mediterranean a few hundred years ago and now he's back to show that he's not such a bad guy after all. If he's in the right mood, he'll be sharing all of that stolen gold thanks to the top features and cascading reels. Here's how the rest of the game shapes up.


Peter & Sons always produce a visually pleasing slot and Barbarossa DoubleMax is no different. It takes place in a typical pirate's cove with palm trees swaying in the background. The symbols are pretty standard for this type of theme with an anchor, a bottle of strong booze and various pirates making an appearance. 

Watch out for the cannonballs as they are dragged to the left and explode onto the reels with each cascading win.

All of the above looks great regardless of the size of the device you are using and Android and Apple users can both get involved. 

Game Play

The addition of the DoubleMax feature is a first for Peter & Sons and it has really given this production a genuine boost of power. The base game doesn't feel like a hard slog as you wait for the free spins bonus to appear. 

In fact, there is plenty of enjoyment and big wins to be found right there in the regular part of the production. Naturally, the biggest wins are more likely to occur during the free spins round thanks to the DoubleMax multiplier not resetting between wins.

Win Potential

This pirate ship is weighed down by a hell of a lot of plundered gold. A 20,000x max win is a very tempting offer and this is accompanied by high volatility and a range of RTPs that can peak at 96.2%.

Our Verdict

Barbarossa DoubleMax is a good-looking slot and bears a few of the Peter & Sons trademark audio-visual touches. The addition of Yggdrasil’s fantastic DoubleMax feature is a huge bonus which really makes it worth getting on board and seeing where this ship takes you for a while.
