About Mr. Oinkster's Key to Riches
Mr. Oinkster's Key to Riches welcomes you back to the wealthy pig's mansion, where 5 × 3 reels with 40 fixed paylines sit among expensive furniture and a giant vault. It's the newest twist in the Mr. Oinkster series, and the middle of the grid is where to look.
Inside Mr. Oinkster's Key to Riches
Wild Reel coin unlock
Wilds appear on the central Wild Reel. When one lands alongside coins anywhere on the grid, it unlocks every visible coin and pays out their values, and coins can also hold prize pots from Mini to Grand.
Wild Modifier nudges
When a wild lands in the base game with no coins in view, it may trigger the Wild Modifier, which picks one to five positions and nudges each into a coin or a winning symbol.
Two piggy bank bonuses
Collected wilds fill two piggy banks, and either can open free spins. Multiplier Free Spins add a fresh coin multiplier every spin, Double Wild Reel Free Spins run two Wild Reels at once, and together they form the Super Feature.
Mr. Oinkster's Key to Riches questions
Is there a way to open a piggy bank sooner?
You can buy one. The Mystery Bonus and the Super Bonus are on sale whenever you like, and either one starts the bonus feature on the spot.
