Oink Oink Oink Slot by Playtech

Three jewelled piggy banks line up over the reels, one red, one green, one blue, named Grunt, Snort and Squeek. Coloured Coin symbols land during play and drop into the pig that matches their colour. Fill a bank to the brim and it shatters into that pig's feature. Coins do the slow work, but faster triggers exist too: three or more gold Hammers pop a feature on the spot, and three Scatters break a bank open early.

Grunt, the red bank, runs the jackpots. You turn over gold pigs, each hiding a Mini, Minor, Major or Grand tag, and keep picking until three of one label show up. That tier is your prize: Mini 20x, Minor 50x, Major 200x, or the Grand at 2,000x. The Grand is the top payout on the game and the only place to win it. And 2,000x is a modest ceiling for a game built around a jackpot ladder.

Snort's green bank hands over free games, though the length is random, 6, 8 or 10 spins played on an expanded board of either 1,024 or 3,125 ways instead of the base 243. Green Coins carrying a +1 each tack another spin onto the count. Squeek's blue bank is a single wheel spin. It pays cash between 5x and 120x, or it skips the money and drops you into the red pick or the green free games instead, so the blue wheel can be a springboard rather than a payout.

The Wild covers everything except the Scatters and the Coins, so it never blocks a deposit. The setting is a glossy vault done in purple and gold, the three grinning cartoon pigs sitting above card royals and a run of cash-themed premiums: a fat wallet, a blue safe, a gold dollar sign. It looks the part. But the base game between features is plain, standard 243-ways spins with little happening until a bank fills or a Hammer lands, so how much you enjoy it comes down to how often those coins turn up.
