Boom Pirates review

We first heard about Boom Pirates a few months ago, but for whatever reason, it was delayed in production. And though we were curious here at JohnSlots to see what this Foxium and Microgaming collaboration would bring, we now couldn’t care less about the delay. The product is fun, fiery and full of energy, including unique features to leave you wanting more!

The pirate theme is always fun when it’s done well, and Foxium have gone out of their way to bring you a lively animated slot with quirky characters and plenty of thrills. Read on to learn all about this slot and why it’s fast becoming a new favourite.

Boom Pirates bonus features

The standout feature of Boom Pirates has to be the Wonderways mechanism, which sees the base game expand to allow for more reels, more rows and literally millions of more paylines.

In saying that, there are plenty of other features to look out for in this fast-paced slot, and you’ll even have the option to trigger them more easily. We’ll go through all the features now in more detail to give you an idea of what to expect.


If you happen to randomly hear a pirate shout out “boooooom pirates!”, you’ll know something big is about to happen.

This is the random Boom Pirates bonus round, which sees the pirates fire cannon balls onto the base game and trigger the Wonderways mechanism. The grid will expand, and suddenly you’ll be playing with 10,077,696 paylines.

Free spins

10 free spins can be won from the base game when the three scatter symbols appear on reels one, three and five to reveal the phrase “Yo Ho Ho”. The exciting thing about the free spins round is that you’ll also have the chance to activate the Wonderways feature, which will unlock the 10,077,696 ways to win.

Buying Bonuses

If you love the free spins round but wish it hit more frequently, your wish is Foxium’s command. The Foxify feature to the side of the reels allows you to increase your chances of triggering free spins, at the cost of a 50% increase to your current bet.

If you’d rather ensure your chances of hitting free spins, you can go for the Buy bonus, which will cost 100x your stake but trigger the free spins round instantly.


Interestingly Boom Pirates doesn’t have an actual wild symbol – but what it does have is Mary’s Swashbuckling Attack. This is a feature that can randomly trigger on any non-winning spin, and you’ll see Mary swing across the reels to transform five symbols into five of a kind.

Boom Pirates jackpot

There may not be a jackpot in Boom Pirates, but with that huge number of ways to win and prizes of up to 3,800x your stake up for grabs, there’s still plenty to get excited about.

RTP and volatility

The return to player in Boom Pirates is pretty average, but the medium to high variance offers higher-than-average prizes when they do hit. We love the fact that you have the chance to alter the variance a bit in this game with the free spins round.
