Last updated: June 28, 2022

Folsom Prison slot was released in June 2022 by rule-bending casino game company Nolimit City and is an excellent follow-up to their first prison-themed San Quentin Slot. Interestingly, Folsom Prison is another notorious prison that's not all that far from San Quentin state prison, just outside San Fransico, California. Folsom Prison is a maximum-security prison because it homes some of the most dangerous convicted felons in the USA. So how will this play out in an online slot, we hear you ask? Good question! This is what our Folsom Prison slot review is going to find out.

How To Play Folsom Prison Slot

To play Folsom Prison Slot or even give it a demo, you'll need to find an online casino that offers the game. This shouldn't be a problem because in 2022 almost all online casinos (the good ones anyway) have integrated the entire game portfolio from the manufacturer of Folsom Prison slot - NoLimit City. If you are looking for a new casino to try out, or perhaps you're after a new welcome bonus, check the best casinos to play Folsom Prison slot below (they're all approved and UKGC licensed =legit).

Once logged in to your preferred online casino,  load the game on your device and set the betting levels you're most comfortable with. This means the amount you will bet per spin. In Folsom Prison slot, the stakes range from 20p to £120 per spin, so set the controls to the levels you're relaxed playing with. At this stage, it's worth checking the game's paytable and rules, which you can open by clicking on the information icon. It's a good idea to get to grips with games higher paying symbols and which sequences land the most significant wins, so you know what to look out for, but we cover that below too. When you're ready, now's the time to play Folsom Prison slot for real money - so hit the spin button to begin!

Folsom Prison Slot Features

Before we get on to the game mechanics and extra features, let's set the scene regarding visuals. As you can probably imagine, the Folsom Prison slot has a rough, rugged and brutal theme. The story of the slot is based on five inmates, and you have front-row seats into their lives "in the can". The Folsom State Prison, known as FSP, opened in 1880 and is California's 2nd oldest prison (after San Quentin) and has executed over 100 felons on death row in its time.

Cold-blooded and tough as nails, the five inmates will take you on a tour of the reality of one of the harshest prisons. Being in the wrong crowd can get you into a lot of $h!t, according to Nolimit City, so you're going to need to smuggle in something sharp and be on your guard. Graphically, Folsom Prison carries the same look as Nolimit City's horror-themed Mental slot in terms of colourings, more sepia than bright colours, if we're honest.

Where the soundtrack is concerned, it's reminiscent of a Johnny Cash-style sound (let's not forget that Folsom State Prison is also perhaps best known for hosting Johnny Cash during two concerts in the 1960s) so the soundtrack is distinctly different from the hip-hop theme that the San Quentin slot has. Symbols on the reels include low-value A, K, Q, J and 10 royals. The five inmates represent the higher-value symbols. The characters in this prison story consist of: 

  • Fresh Meat: is in for robbery for two years.
  • Backstabber: is in for racketeering for 12 years.
  • The Fixer: is in for 22 years for extortion.
  • Shivy Impala: is in for vehicular homicide. Shivy Impaler has a life without parole sentence.
  • Shankman: is in for multiple homicides, with a life without parole sentence. Shankman is the best-paying symbol with 3, 4 or 5 on a payline awarding 0.6, 1.2 or 2.5 x bet, respectively.

Folsom Prison slot comes with two Wild symbols: One with a red rose in the background and another with a cockroach nest illustrated (lovely...). Both Wilds can land on any reel except for the first reel (i.e. they can land on reels: 2, 3, 4 or 5). The job of the Wild symbols is to substitute for any paying symbol described above.

Other symbols you'll come across when you play Folsom Prison are  Folsom Prison State Scatter symbols and the xWays and xSplit symbols that are distinctive to specific Nolimit City Slots, including Karen Maneater, Punk Toilet and Tombstone RIP Slot.

The reel layout in the Folsom Prison slot is pretty standard. It's a 5 reel game but comes with xWays and xSplit symbols, which increase the number of ways to win up to 46,664. When it comes to features, Folsom Prison is packed full of exciting and theatrical features, 6 in total, and they are as follows:

xWays feature

The xWays symbol is exclusive to Nolimit City slots and can appear on any reel. When you activate the xWays feature, it'll transform into a regular paying symbol and reveal 2 to 4 symbols of the same kind. The xWays symbols opens one symbol above and one below on the reel it appears on. This feature aims to increase the number of ways to win.

xSplit feature

Another exclusive feature you'll only find when playing Nolimit Slots is the xSplit feature. xSplit symbols will only appear on the middle two rows, between rows 2 to 5. The xSplit feature will be activated when they land. xSplit symbols are a clever feature whereby they will split the entire row they land on so that they double the number of ways to win. What's more, the xSplit symbol also splits itself into 2 more Wild symbols.

💡 Split Scatters also give you an extra free spin when you trigger a bonus feature and open up additional locked cells. Furthermore, Cockroach Nest Wilds will multiply by 1 when they are split.

Cockroach Feature

Everyone's nightmare, at least for us. Unsurprisingly, Folsom Prison has a cockroach problem, but perhaps these little critters can help you win something. The Cockroaches appear on the three middle reels; their job is to open locked cells to give you more ways to win. A singular cockroach has a starting position that is replaced by a Wild. If the Cockroach walks above the reels, it'll add its multiplier to any symbol it passes. Multiplier values are 1, 2, 3, and 10. Furthermore, if a nest holds two eggs, it upgrades a Cockroach and clones one more Cockroach for even bigger payouts. Cockroaches can go anywhere, but their nest always breeds in the active positions on the middle three reels (or from transformed Scatters).

Walk The Line Feature (Folsom Prison Free Spins)

This is essentially a free spins game. You'll activate the Walk the Line bonus feature when you land three scatter symbols. When you do, you'll trigger 8 Walk the Line free spins. Each spin in this bonus feature starts with reels in a 2-4-4-4-2 formation, with at least 1 Cockroach guaranteed. If you land a Scatter during the feature, you'll be awarded additional free spins and will upgrade the bonus round to 'The Chair' (see below).

The Chair

In this feature, the grid starts active in a 4-4-4-4-4 formation, and at least 3 Cockroaches are guaranteed. When you land 4 Scatters during the base game, you'll be awarded a total of 8 'The Chair' free spins. The xSplit and xWays symbols can also land, leading to 46,664 ways to win in total!

Nolimit Bonus

The Nolimit Bonus feature can be activated when you hit the yellow star icon. Here you can buy a bonus feature that will enhance your odds, for a price. The features consist of:

Extra CostFeatureRTP %
x 68 BetWalk the Line feature96.36%
x 1,500 BetThe Chair feature96.31%
x 82 BetLucky Draw Option #196.46%
x 355 BetLucky Draw Option #296.20%
x 784 BetLucky Draw Option #396.33%

What's more, there are also three' lucky draw' choices, displaying prices from x82-784 the bet, depending on the odds of getting each bonus.

⚠️ Please note that the Nolimit Bonus feature is unavailable in the UK due to legislative rules enforced by the UK Gambling Commission.

Meet your Maker Feature

The "Meet Your Maker" screen is a screen shot you'll want to see. It's one of Nolimit City's maximum win screens which is only shown to players lucky enough to hit the maximum win prize. When playing Folsom Prison Slot, the Meet your Maker win screen is shown to any player who hits the maximum win of x75,000.

Maximum Win Potential & Jackpot

Folsom Prison doesn't offer a progressive or local jackpot but provides sizeable wins. The maximum win per spin is x75,000, your total bet. This is won every 6.5 million spins (on average), which sounds like a hefty number, but that number is soon swallowed up since the slot is very popular. The bigger wins will come from the cockroaches, which open locked cells, as well as from the Wilds and multipliers of up to x10. When you hit the maximum win of Folsom Prison slot, you'll be lucky enough to see the exciting "Meet the Maker" screen as mentioned above.

Folsom Prison Slot RTP % & Variance

The Folsom Prison RTP is 96.07%, which is slightly higher than the 96% "norm" when talking about most online slots. In Nolimit City's words, the volatility of Folsom Prison slot is classed as "Insane' which isn't a huge surprise when talking about Nolimit City games and slot variance in the same sentence. Extremely volatile (10/10), Folsom Prison may be too volatile for some, though the hit frequency rate is 22.62%,which roughly equated to a win every 4.4 spins.

Folsom Prison Slot Review - Our Verdict

We told you this game isn't about kittens, glitter, candy or rainbows. It's grim, but the features are clever - it's a perfect slot if you want a view into another world away in one of America's most notorious joints. If you're a fan of Nolimit City slots, you'll like this one, though you may be left thinking that it doesn't quite come up to the same level as the San Quentin slot (the slot game that put Nolimit City on the map), but we'll let you be the judge of that.

The features are fun, especially the Cockroaches, which infest the hellish prison in the bonus features. Landing The Chair feature is the clear draw in this game, as three cockroaches are guaranteed to land on every free spin (as opposed to just 1 in the Walk the Line feature). The Chair feature also begins with more ways to win, offering you an increased chance of achieving the game's max win of x75,000 - at which point, you'll activate the unique 'Meet The Maker' screen. And that's the screen you'll definitely want to see.

This slot game is a brilliant concept with come complex features though it's not complicated to play. The question is, can you hack the theme? It's quite brutal though, if you can, Folsom Prison online slot is well worth a spin from a game provider that never fails to impress.
