Steel bulkheads creak, a brass porthole leaks bubbles, and the reels sit wedged inside what used to be a torpedo bay. That's the opening shot of Piranha Trio, the underwater chapter in Ash Gaming's Trio family for Playtech, which arrived around April 2026 after a long parade of siblings (Gold Trio: Sinbad's Riches, Tres Amigos, Santa Surprise, Football and the rest).
Math first. You're looking at a 5×3 grid with 30 fixed paylines, an RTP of 95.91%, and medium volatility. So the swings won't tear your bankroll in half on a bad night, though they also won't print a quick max win out of thin air. Wilds stand in for paying symbols, scatters punch the bonus door open, and the high-pay ladder runs through starfish, amphora, shell, anchor and the lighthouse at the top. Standard Ash architecture, really, with letters at the low end pulling tiny 1x line returns.
The hook is the trio sitting above the reels in their little fishbowls. Blue handles Boost, red runs Multiply, green takes care of Collect. Land three or more scatters and you enter Trio Respins, which gives you exactly 3 spins on a frozen board where coin symbols stick around. Depending on which piranhas wake up, you might play with one feature, two, or all three stacked. Solo Boost? Fine. Boost plus Collect plus Multiply firing in sequence? That's where the screen gets loud.
And then there's the jackpot ladder: Mini at 10x, Minor at 20x, Major at 50x, Grand at 1000x. Mystery coins drop during the respins, and any of them can carry a tier. The Grand sits at EUR 5,000 on the default EUR 5 stake, which is a respectable ceiling without being absurd.
Two shortcuts exist if you don't want to wait. Buy Feature drops you straight into Trio Respins for roughly 50x your bet, the same price tag every Trio sister uses. Extra Chance, an ante toggle, bumps your spin to around 6 currency units instead of 5 and pushes the feature rate up. The cartoon-piranha aesthetic gets a bit repetitive after a longer session, honestly, but it's hard to fault the engineering. If you've played any Gold Trio entry, you'll feel right at home; if you haven't, this is a clean place to start.
