Piggy Heist

Play'n GO sets Piggy Heist inside a bank-vault robbery run by a crew of pigs, reusing the coin-collecting engine it built for an earlier release, Crabby's Gold, under a new setting; a safe and a vault door frame the grid in place of that game's pirate scenery.

The reels run 6x4 with 4,096 ways to win, and stakes range from 0.10 to 100 per spin, with Vault Wild progress tied to bet size. Medium volatility, rated 6 out of 10, sits alongside a hit frequency of roughly 1 in 3.09 spins. J-to-A symbols make up the low pays; five higher-value character symbols form the premiums, paying 1x the bet for six-of-a-kind royals or 2x to 5x for the characters. Wilds substitute for any paying symbol on every reel except the leftmost.

Coin Pouch symbols on the outer reels collect Coin symbols worth 0.5x to 25x the bet as they land elsewhere on the grid, and a second Coin Pouch doubles the collection. Coins left uncollected are gathered by the Safe instead, and a Safe collection can randomly launch Hold'n Spin, where coins land face-down and stick to the reels for three respins, a count that resets whenever a new coin appears, up to 30 respins in total; values are revealed at the end, worth 1x to 30x each.

Winnings from Hold'n Spin can be risked in the Vault Gamble: a single spin lands Double Coins or Police Badges, doubling the collected total if Double Coins dominate or wiping it to zero if Badges do, repeatable up to four times.

A separate meter fills as stethoscope symbols land, and every six collected unlocks a stronger Vault Wild for the base game — standard wilds give way to multiplier wilds worth x2 to x5, then expanding and multiplier-expanding versions, then walking wilds that shift one position left with each respin for up to ten spins, and finally a 2x2 wild covering four positions at once. Only one wild type shows at a time, up to two of the largest, and any multiplier wild passes its value on to the rest.

Piggy Heist's maximum win reaches 70,000x the stake, with alternate RTP settings available at 94.25%, 91.25%, 87.25% and 84.25% alongside the default 96.25%.
