Three smirking demon piglets perched on top of the reels, a bouncy soundtrack that has no business being this cheerful, and a cave glowing red behind a 5×3 grid stacked with pentagram coins. Piggy Inferno is mildly satanic in a Saturday-morning-cartoon way, with horns, tridents and burning dice symbols presented playfully enough that the theme reads as cute rather than gothic. Platipus dropped this 25-line slot in October 2025, and the demo loaded on this page is the most direct route to meeting the three pigs who drive the bonus round before any real-money commitment.
The wild is a horned red imp that substitutes for everything except the bonus coin. It only appears on reels 2, 3, 4 and 5, so the leftmost reel is always live with a paying symbol. The bonus is the gold pentagram coin, which can land anywhere on the grid and triggers the Respins feature when enough appear. Each bonus coin carries either a cash value (10x to 100x bet) or one of the four jackpots.
Three or more bonus coins lock the feature into life. All bonus symbols stick on the reels, the remaining positions keep spinning, and three respins are awarded to find more. Every fresh coin landing resets the counter back to three. The feature ends when respins run out, or all 15 grid positions are filled with bonus coins, at which point every locked value is summed up and paid as a single feature win.
Above the reels sit three demon pigs, each triggering a different twist when their colour-matched bonus symbol lands:
Land all 15 coins on both boards, and Piggy Inferno pays out two Grand Jackpots in one round.
The piggy modifiers that can modify the respins round.
Bonus coins carry one of seven cash prizes (10x, 20x, 30x, 40x, 50x, 80x or 100x bet) or one of four fixed jackpots. The Mini lands at 150x, Minor at 300x, Major at 1,000x and Grand at 10,000x your stake. Filling every position on the grid with bonus symbols of any type also awards the Grand Jackpot. The 10,000x ceiling is the hard cap on the slot.
For players who would prefer to skip straight to the pigs, the Buy Bonus button locks in 95x the current total bet and guarantees the next spin triggers Respins. The buy feature shares the same 96.07% RTP as standard play, so there is no statistical penalty for buying in.
Piggy Inferno uses a 5×3 layout. All 25 paylines stay active on every spin and read leftmost-first from reel one across the grid. The stake control sits in the lower toolbar, with a minimum of 1.00 and a maximum of 100. Three or more matching icons on a single payline qualify; where two combinations share a line, only the larger pays.
Two controls matter beyond the spin button. A Hold-for-Turbo option in the bottom-right strips animations down to their fastest setting, and the orange Buy button skips into Respins for 95x bet. There is no Ante Bet equivalent. Every spin runs at the same trigger probability, so the only meaningful choice between spins is whether to hunt naturally or pay to play the bonus.
High volatility is the default expectation here. The hit rate sits around one win every four spins, which is generous on paper, but the size distribution leans hard towards small line wins between bonus rounds. The Respins feature is where the numbers actually live, and that is true whether you trigger it organically or buy in directly.
Each row of the table is quoted at the default per-line bet of $0.10. Per-line bet scales linearly with total stake, and the table values scale with it.
