Pirate's BOOM is an online slot from KnockKnock Games with an RTP of 96.00%.
Page updated July 2026
Pirate's BOOM, from developer KnockKnock Games, takes the pirate slot theme in a loud, explosive direction, with the all-caps "BOOM" in the title setting the tone for a game built around cannon fire, gunpowder and dramatic reel action rather than quiet treasure-map exploration.
Expect a reel set leaning into the more chaotic, action-heavy side of pirate lore — cannons, exploding barrels, and a crew more interested in a fight than a quiet haul. KnockKnock Games tends to favour bold, high-contrast visuals and punchy animations, which suits a title built around explosive moments. Detailed reel and payline information hasn't been confirmed for this particular release, so it's worth checking the paytable inside the free demo to understand the exact grid structure before playing with real money.
Pirate's BOOM carries a theoretical RTP of 96.0%, matching the broad industry average for online slots. That's a solid, dependable number — over a large enough sample of spins, the game is built to return roughly £96 for every £100 wagered, though short-term results will naturally swing well above or below that figure.
No confirmed volatility rating is available for Pirate's BOOM at this stage. Given the explosive framing, it's plausible the game leans towards bigger, less frequent hits, but that's speculation rather than confirmed fact — running through the free demo for a decent stretch of spins is the best way to gauge the real rhythm of wins.
Maximum win multiplier and the specific stake range haven't been confirmed for this title, so checking the in-game paytable directly is the recommended way to establish the ceiling payout and betting limits before wagering real money.
Pirate's BOOM promises a louder, more combustible take on the well-worn pirate slot theme, backed by a solidly average 96.0% RTP. It should appeal to players who want their pirate adventures delivered with a bang rather than a slow build.
