Theme – Audio & Design Features – break the piggy bank for fat rewards


Like most games in the NetEnt catalogue, there’s a slick and stylish look to the Pork Knox slot. With a piggy/crime theme, it’s loosely based on Fort Knox which is the US Army installation in Kentucky that houses a large portion of the US’ official gold reserves.

A rather elegant bank at night is the setting here. You’ll hear a rather jaunty, jazzy soundtrack playing in the background while you spin. It’s a bit of a toe-tapper and adds to the atmosphere nicely.

The reels are flanked by sturdy marble columns and filled with playing card suit symbols which spin alongside a gold key, a money clip full of notes and a pouch full of coins. The most lucrative symbol is the stack of gold bars. Land 3, 4 or 5 of these on a payline and you’ll pocket a payout equal to 4, 8 or 15 x your total stake.

There’s isn’t a wild here but there is a scatter symbol (the safe). Landing 3 or more of these on the same spin activates the feature round.

Pork Knox is available to play on all devices including desktop and laptop computers, tablets and smartphones. It’s been created using HTML5 technology so good to play on the go.

Pork Knox Bonus Features

There’s plenty to get stuck into when it comes to the features in Pork Knox. As well as Mystery Symbols there are 3 triggered bonus rounds which offer free spins with multipliers, pick me prizes and the Cash Stacker. There a total of 4 bonus features.

Mystery Symbols feature

The stack of gold coins is the game’s mystery symbol. All mystery symbols that land on the same spin will morph into the same matching symbol. Known as the Mystery Symbols feature, a new payout consideration is then made with the transformed symbols in position.

3 Bonus Features

Land 3, 4 or 5 safe scatter symbols anywhere on the reels on the same spin to activate the bonus features. Pick one of the 3 safe scatters which will reveal which of the following 3 features you’ll go on to play:

Free Spins feature

3, 4 or 5 scatters will give you 10, 15 or 20 free spins. Regardless of how many free spin you get, a 3x multiplier is active throughout meaning that all payouts are trebled.

Instant Win feature

This is a classic pick me bonus. Choose from the safe symbols to reveal cash prizes which can range from between 7.5 and 250 x your total stake. If you triggered the bonus with 4 or 5 scatters, prizes from the Instant Win are doubled or quadrupled. This means wins of up to 1,000 x your total stake.

Cash Stacker feature


This feature plays out on a new set of reels that are set up in a 5x6x7x6x5 formation. These reels are made up solely of blanks and Cash Stacker symbols that come with values of 0.25 to 15 x stake attached.

When a Cash Stacker symbol lands, it drops to the lowest position on that reel and stays there for the rest of the round. You’ll start this feature with 3 spins. The spins tally resets to 3 each time you land a Cash Stacker symbol.

If you manage to fill the whole of row 2, 3, 4 or 5 with Cash Stacker symbols, it brings a multiplier of 2x, 3x, 4x or 5x into play. If you manage to fill the whole of reel 2 with Cash Stackers, you’ll trigger the Mini Jackpot. This is worth 10 x stake. Better still is the Midi Jackpot worth 30 x stake which is awarded if you fill reel 4 with Cash Stackers.

The progressive Mega Jackpot is awarded if you manage to fill all 7 positions on the middle reel with Cash Stackers. When you’ve used up all your spins, the values attached to the Cash Stacker symbols are added together and boosted by any active multipliers or jackpots to give you an overall prize.

Pork Knox Review Summary – a porky clone

I enjoyed trying to break the bank in the Pork Knox slot. The rather elegant design is very stylishly done. There’s plenty of variety when it comes to gameplay too with the free spins with 3x multiplier, pick me round and Cash Stacker offering ample opportunities.

However, it’s a clone of the Vegas Night Life slot with a piggy/crime theme twist. The max wins of 900 x stake per free spin (with the 3x multiplier) isn’t that appealing. The biggest wins will come from the progressive jackpot.

If you want pigs, NetEnt’s very own Piggy Riches is a real favourite which offers 36,000 x stake max wins. Looking to break into vaults and banks for riches? Royal Mint Megaways by Big Time Gaming would be my pick as it comes with a high 96.68% RTP rate and 41,300 x stake wins.
