Boom Pirates is a swashbuckling, cannon-loud video slot distributed by Microgaming that drops you onto a tropical pirate outpost where every spin can trigger an explosive grid expansion. If you like modern “ways-to-win” gameplay, constant screen movement, and bonus features that can flip a quiet spin into a sudden payout, this one is built for you.
The vibe is bright and adventurous rather than dark and gritty: think sunlit shorelines, ramshackle docks, and Captain Mary calling the shots. Under the hood, Boom Pirates mixes a dynamic reel setup (that can grow dramatically) with a couple of signature mechanics—one that blasts the grid bigger and another that can rescue non-winning spins. It’s a great fit for casual players who want simple controls and for seasoned slot fans who chase high-energy bonuses.

Key Features and Gameplay Mechanics
At its core, Boom Pirates is all about expanding potential. The base game starts on a compact grid, but the right moments can open extra reels and rows, turning the screen into a much larger ways-to-win battlefield. The result is a slot that feels different from spin to spin—perfect if you get bored of static 5x3 layouts.
Reels, Rows, and Ways to Win
The game begins on a 5-reel, 4-row setup, then can expand up to a much larger layout (commonly seen up to 9 reels and 6 rows). Wins are paid as ways rather than fixed paylines, meaning you’re looking for matching symbols connecting from the leftmost reel across consecutive reels.
- Starting ways-to-win: 1,024 on the base grid
- Maximum ways-to-win: up to 10,077,696 when fully expanded
Because expansions increase the number of symbol positions on screen, they also increase the number of possible winning combinations. That’s the main “why” behind the game’s boom-and-bust rhythm.
How Wins Are Formed (No Paylines Needed)
In Boom Pirates, you don’t need to line up symbols on a specific line. Instead:
- Wins typically count when matching symbols land on reels 1+ and continue on adjacent reels to the right.
- Multiple matching symbols on the same reel can create multiple ways to complete the same win.
- Grid expansion can dramatically increase the number of combinations on a single spin.
This makes the base game easy to follow, while still giving advanced players plenty to analyze when the screen grows.
Symbols and Theme Highlights
The symbol set leans into classic pirate storytelling: crew members, treasure-themed icons, and Captain Mary as a standout character. While exact payouts depend on your stake and the in-game paytable, you can generally expect character symbols to be higher value than the simpler, lower-tier icons.
One notable design choice: wild symbols aren’t a core part of the experience in most versions of Boom Pirates. Instead of relying on wild substitutions, the game’s excitement comes from expansion events and the special “save” feature tied to Captain Mary.
Bonus Features and Special Mechanics
Boom Pirates doesn’t hide its fun behind complicated mini-games. The bonuses are straightforward, highly visual, and designed to trigger momentum—especially once you enter free spins.
Free Spins (YO-HO-HO Scatters)
The main bonus round is triggered by scatter symbols spelling out the pirate chant. In the most common ruleset, you’ll need three scatters landing on reels 1, 3, and 5 to activate the feature and launch 10 Free Spins.
During free spins, the game leans harder into its expansion identity, giving you more chances to open the grid and stack up ways-to-win.
Free Spins Retriggers (+5 Spins)
Free spins can be extended. If you land three scatters during the bonus (often on any eligible free-spin spin), you’ll typically be awarded +5 extra free spins. If you like sessions where a bonus can “keep going,” Boom Pirates has that potential—though retriggers are never guaranteed.
Boom Pirates Expansion (Cannon Blast Grid Growth)
This is the signature mechanic players remember. At random moments, the pirates unleash cannon fire that can activate extra reels and/or rows, increasing the grid size and your total ways-to-win. Think of it as the game physically opening up more space for symbol combinations.
A key twist is how this interacts with the bonus round: during free spins, any activated expansion areas can become sticky/persistent for the remainder of the feature, meaning the screen can stay enlarged and keep your ways-to-win elevated while you spin out the rest of the round.
Mary’s Swashbuckling Attack (Non-Win to Five-of-a-Kind)
Captain Mary brings one of the coolest “second chance” mechanics in the slot. After a non-winning spin, Mary’s Swashbuckling Attack can randomly trigger and transform the outcome into a guaranteed five-of-a-kind win.
This doesn’t mean every dead spin gets saved—only that the game has a built-in way to inject surprise payouts, which can smooth out some of the quieter stretches (especially helpful in a medium-to-high volatility slot).
Foxify Option (Stake Boost for Feature Frequency)
If you want to chase features more aggressively, Boom Pirates may offer a Foxify option. When enabled, it increases your stake (commonly by 50%) in exchange for an improved chance of triggering key events such as expansions and/or free spins.
Practical take: Foxify can make the game feel more “active,” but it also increases cost per spin. It’s best treated as a session mode rather than something to toggle randomly without a plan.
Feature Buy (Buy Free Spins)
In some jurisdictions and configurations, Boom Pirates includes a Feature Buy that lets you purchase entry into the Free Spins round instantly (often priced at 100x your current stake). This is designed for players who prefer concentrated bonus hunting over long base-game grinding.
Important: Feature Buy availability can depend on local rules and game settings, so always check the in-game menu before expecting it.

Gameplay Tips for Boom Pirates
There’s no guaranteed strategy for slots, but you can make smarter choices about pacing, feature chasing, and volatility management.
1) Treat Expansions as the “Real Game”
The base grid is only the starting point. If you’re judging the slot too early, you’ll miss why it’s popular. Give yourself enough spins to see at least a few expansion moments, because that’s where the ways-to-win count starts to matter.
2) Use Foxify With a Budget, Not a Hunch
Foxify raises your cost per spin. If you enable it, decide in advance:
- How many spins you’ll run with Foxify on
- What your stop-win and stop-loss points are
This helps you avoid “tilt toggling” where you chase features by repeatedly increasing spend mid-session.
3) Feature Buy Is High-Intensity—Plan for Variance
Buying free spins can be fun because it cuts straight to the action, but it also concentrates volatility. If you’re going to use Feature Buy (where available), consider lowering your stake first so the buy-in cost stays within your comfort zone.
4) Let the Bonus Round Breathe
Because free spins can retrigger and expansions can stick, the best sessions often come from letting the feature play out fully rather than skipping animations too quickly. The game’s momentum is part of its entertainment value—and it helps you track what’s been activated.
