Get ready for swashbuckling adventure on the high seas with Boom Pirates online slot, a vividly presented game from Microgaming and Foxium. Join a motley crew of Pirates led by Captain Mary on a quest to pillage the riches of an island. Expanding reels, a Foxify feature and Mary’s special swashbuckling attack make this feature-rich title an enticing game.

Game Symbols

  • Captain Mary, a pirate with bomb, a Parrot and cannon represent the higher value symbols.
  • The low value symbols are in the form of card suit symbols.
  • Yo Ho Ho symbols act as scatters, triggering free spins.  
  • There is no actual wild symbol for this game, instead there 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 for an instant win.

Bonus Features

Wonderways / Boom Pirates

The Wonderways mechanism enables expansion during the base game to allow for more reels and more rows and many, many more paylines. The Boom Pirates bonus round is completely random and kicks in after someone yells “boooom pirates!”. Cannon fire bursts across the reels, expanding the grid to 9 x 6, giving you an astonishing 10 077 696 ways to win!


The Foxify feature found on the side of the reels allows you to increase your chances of triggering free spins at a cost of a 50% bet increase.  After a non winning spin, while the feature is active, Captain Mary herself swings across the reels, changing symbols to reward the player with a five of a kind win.

Free Spins

Landing 3 scatters on reels 1, 3 and 5 triggers the free spins feature, awarding you 10 free spins.

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

Our Verdict

Boom pirates is a fast, fiery and fun to play, with impressive in-game mechanics and features. The return-to-player is modest, but the medium to high variance offers higher-than-average prizes when they do hit. The fact that you can alter the variance a bit with the free spins round, that massive number of ways-to-win, and up to 3800x your stake up for grabs gives you plenty to be excited about in our opinion.
