Piranha Bite Club

Exco sets Piranha Bite Club on a beach overrun by piranhas, rendering the scene in a brushstroke, oil-painting style rather than clean digital art. The reel frame is filled with 1950s-style pin-up and travel-poster characters — sunbathers, a lifeguard, a harpoon-wielding local and more — caught mid-panic as the fish close in, giving the slot a distinctly retro, illustrated look rather than a modern cartoon one.

The grid runs 5 reels by 5 rows with 35 paylines, and five-of-a-kind wins pay 0.5x to 0.75x the stake for the card-rank symbols or 1.5x to 5x for the character symbols — the lifeguard, captain, coconut-drinking woman and harpoon character among them. Piranha Wilds land across the base game in blocks of 1x1, 1x3 or 1x5, and a wild that lands only partly on screen nudges into full view rather than staying cut off; a full line of five wilds pays 5x the bet. A separate Multiplier Reel sits above the main grid and can hold a value that drops down whenever a wild lines up in the same column, multiplying every win that passes through that wild.

Landing three scatters opens five free spins, four scatters step that up to seven, and five scatters unlock the full nine spins on offer. Regular symbols disappear during the round, replaced entirely by sticky, fully stacked piranhas and multiplier symbols — piranhas pay out the value shown on the accompanying Prize Reel every time a new one lands, and any of them can carry their own multiplier that boosts the cash figure further. Each piranha or multiplier that lands adds an extra spin to the round, and a grid that fills completely with piranhas grants two additional spins while paying out every sticky fish on every remaining spin regardless of whether a multiplier shows up. A rebuy option lets players pay for one more spin once the round ends naturally, and four separate buy-in tiers sit alongside it: 50x the stake for 5-7 spins, 100x for 7-9 spins, 200x for a guaranteed 9 spins with a shot at the enhanced Super Hack mode, or 500x to buy straight into Super Hack itself, which raises both the multiplier strength and the odds of landing piranhas. A Golden Bet option raises the stake to 1.5x in exchange for a better chance of triggering free spins naturally.

Piranha Bite Club runs at 96.04% RTP with medium-to-high volatility, a 29.8% hit frequency and a maximum win of 15,000x the stake, with bets ranging from 0.20 to 50 per spin. The combination of stacking sticky piranhas, a column-triggered multiplier and four separate ways to buy into the free spins gives the round several different paths to its top payout rather than one fixed route.
