If you want to keep something safe, store it in Fort Knox. Of course, you can’t just ask the US Bullion Depository, known as Fort Knox, to store it, but due to the vault’s safety, it’s become a metaphor for bulletproof protection. Fort Knox is also known for storing some of the world’s most treasured items, including unreleased and rare dollar coins and, at one time, the Magna Carta, the Gutenberg Bible, and the Crown of St. Stephen. More importantly, it holds nearly half of the USA’s gold reserves as a bullion depository. That’s the premise for NetEnt’s slot, Pork Knox, which offers bullion to the luckiest players.

A 5x3 slot game with several great bonus features, Pork Knox’s main highlight is the three jackpots. With some luck and stacks of golden coins, this piggy bank can crack up and give you the prize of a lifetime.

The Pork Knox slot has five reels and three rows with 20 fixed paylines. It’s a pretty straightforward layout and design seasoned with NetEnt’s trademark graphics. The slot looks pretty sharp, just like it’s expected from a NetEnt game, and sounds sharp as well.

To win, you will need to land matching symbol combinations from the left reels to the right. The five reels are flanked by marble columns that feature shiny card royals. In line with the theme, it also features symbols representing wealth, of which the gold bars pay the most. Land five of these, and you’ll get a 15x return.

Of course, the slot has a scatter that plays its well-known role. It’s a pretty excellent slot overall in visual and audio terms, with the jazzy soundtrack suiting it perfectly.

Developed on HTML5 tech, Pork Knox is easily playable across all mobile devices. You can spin it on the go on your Android and iOS device as long as your Internet connection is stable.

To start the game, you will have to set your bet first. The range goes between €0.10 and €100 per spin, suitable enough for all players. In the base game, you can expect straightforward action, lining up (hopefully) high-paying symbols to get to the slot’s vault lined with gold bars.

If you want to hit the higher payouts, you’ll need to find this piggy bank’s special features. The scatter is your key to the vault of specials since there’s no wild to trigger some of them. However, the Pork Knox slot has three bonus rounds plus a regular special feature that can certainly take your wins to the next level.

While spinning the slot, you’ll see stacks of golden coins. This is the game’s mystery symbol that can morph into matching symbols when they land on the reels. As soon as it does that, a new payout will be made.

Landing three, four, or five scatters (safe) will activate Pork Knox’s bonus features. You then get to pick one of the three safe scatters and choose one of three features.

• Instant win: as the name suggests, this feature triggers an instant win. It’s a classic pick’em bonus round where you choose the safe to reveal a cash prize beneath. It goes between 7.5x and 200x your stake. If you start this bonus with four or five scatters, the prizes will be doubled or quadrupled.
• Free spins: you can earn 10, 15, or 20 free spins if you trigger the free spins with three, four, or five scatters, respectively. It’s a classic free spin round with an x3 multiplier applied to all wins.
• Cash stacker: this is the Pork Knox slot Fort Knox feature. The Cash Stacker bonus plays out on a new set of reels with a higher formation. Whenever you land a Cash Stacker symbol, it will drop down to the lowest position on the reels. You get three free spins to begin with, and the number resets to three for every Cash Stacker symbol. You can get multipliers up to x5 for filling five rows with Cash Stackers. Filling all seven reel positions in the middle will trigger the Mega progressive jackpots while filling only a few can lead to the Mini and Midi jackpots.

The RTP of the Pork Knox slot is set to 96.00%. That’s pretty solid for a medium variance slot that pays 1,000x line wins. You can expect much higher payouts with the progressive jackpot, with each bet contributing 3.7% to the pot.

NetEnt rarely misses slots, and Pork Knox is no exception. It’s a nicely designed slot with no major base game action but a barrage of great features. The progressive jackpot is the slot’s Fort Knox, hiding gold bars and unique items that can certainly boost your bankroll if you’re lucky.
