Special features

Boom Pirates Feature

The Boom Pirates Feature can be randomly activated during the base game. Cannons appear and fire at the reels, which activates additional reels and rows, up to a maximum of 9 reel and 6 rows (when 10,077.696 ways-to-win are in play) for a single spin.

The Boom Pirates Feature also comes into play during the Free Spins Bonus Round.

Mary’s Swashbuckling Attack

On any non-winning spin, Captain Mary can swing in on a rope and change a random number of symbols so that they produce a 5-of-a-kind win (in addition to any other wins that result).

Free Spins Bonus Round

Hitting 3x scatter symbols on reels 1, 3 and 5 activates the Free Spins Bonus Round. 10 free spins are automatically awarded, during which hitting 3x scatter symbols will trigger an additional 5 free spins.

During the Free Spins Bonus Round, the Boom Pirates Feature can randomly activate, potentially extending the game to 9 reels and 6 rows, producing 10,077.696 ways-to-win. Once activated, the additional reels and rows stay in play until the end of the feature.

Graphics and Sounds

Like all Foxium slots, the production values on Boom Pirates are exceptionally high. The reels are set on a tropical island, with Mary’s pirate ship ominously monitoring the coast. The symbols include Mary, First Mate Ben and a number of other nautical accoutrements. There are some very exciting visual effects, such as when Mary’s ship fires cannon balls at the reels, or when the Captain swings in on a rope when the Mary’s Swashbuckling Attack feature is randomly triggered.

It is the music, however, which is probably the best feature of the game’s design. It combines classic martial sounding maritime music with modern touches, including driving drums underneath, and these capture the pirate theme very well. The highs and lows in the music also help to accentuate key moments of tension and anticipation.


This is undoubtedly one of the most enjoyable games we’ve played in recent years, particularly for the way in which the gameplay is always changing and evolving but without letting gamification features hold up the main action. As a medium to high volatility ways-to-win slot, regular wins come your way during the base game, plus there are opportunities for huge wins in the free spins round when all 9 reels and 6 rows are in play.

As well as the exciting gameplay, the visuals, sound effects and music are outstanding, and the game is genuinely immersive, with a strong lead character and well-crafted special FX.
