Description of the Slot 

Nolimit City’s queer obsession with prisons is hard to figure out. After releasing San Quentin xWays in 2021, the game provider is back with another Californian jail, Folsom Prison. Perhaps Nolimit City felt the last one was not bleak and foreboding enough. Hence, it pounced on the next opportunity by focusing on a prison known for carrying out 93 executions and its proximity to a burial ground. Let’s just hope the slot lifts our mood with its specs, at least. 

Folsom Prison starts on 5 reels with only 2 active rows at the beginning. But new rows are unlocked as you proceed further into the game, taking the default paylines from 16 to up to 46,664 ways to win. A quick look at numbers reveals the slot’s excellent math model. Played at a high variance level, Folsom Prison comes with an RTP of 96.07% and provides a max win potential of 75,000x the stake. The slot has no shortage of features either, as we get two wilds (including a special cockroach wild), xWays, xSplit, and two bonus modes. 

Design and Audio

Nolimit City has not missed the point of Folsom State Prison being the second largest prison in California: the game opens with the view of an enormous prison fashioned with turreted architecture. It is no surprise that the reels are full of bars for a slot based on a prison. The visuals are washed down in a sepia tone giving the game a part-bleak and part-wild-west vibe. 

The background score is also reminiscent of the cowboy theme except for the singing part, which sounds more like a heavy metal voice going over a blues track. 


We already know that every time a Nolimit City slot is released, myriad unique features crawl their way into the game. It’s the same with Folsom Prison. 


When xWays symbols appear on the reels, they transform into random paying symbols. Also, they unleash 2 to 4 identical symbols on the grid. A reel’s top and bottom locked positions open up if an xWays icon appears on the same reel. Consequently, unlocked symbols increase the number of winning ways. 


xSplit symbols only land on the middle two rows from reels 2 to 5. An xSplit symbol splits the row into two, thereby doubling the number of winning ways. The xSplit symbol also splits itself into two wild symbols. Furthermore, Split scatters provide an additional free spin when the bonus round gets triggered. At the same time, the multipliers of Cockroach Nests increase by +1 when they are split


The prison is full of cockroaches crawling all around the place. But in a typical Nolimit City fashion, even these repulsive insects come handy during the game. Cockroaches appear only in the three middle positions and move about the reels, leaving a wild symbol at their starting point

If a cockroach walks above a locked position, it unlocks that cell. On the other hand, if it walks over an unlocked symbol, the cockroach multiplier is also added to that symbol. Cockroaches at the same position and step convert that position into a wild

During the bonus game, a Cockroach Nest may land but remains inactive until a Cockroach walks over it. After coming in contact with the cockroach, the multiplier increases for the remainder of the bonus round up to 3 times with values of x1, x2, x5, and x10

If a nest contains 2 eggs, it upgrades the Cockroach level. Additionally, a cockroach clone is created, which remains active throughout the bonus game. 

Walk the Line 

Hitting 3 scatter symbols anywhere on the reels triggers the Walk the Line bonus feature. Initially, 8 free spins are awarded, but an additional free spin is won if a scatter is affected by an xSplit symbol. Each spin during the bonus game starts on a 2-4-4-4-2 reel formation with at least 1 cockroach guaranteed. Additional free spins are won by landing a scatter symbol during the bonus game, which also upgrades the round to The Chair segment

The Chair 

Landing at least 4 scatter symbols during the base game triggers The Chair feature with 8 free spins. The feature starts in a 4-4-4-4-4 formation with at least 3 guaranteed cockroaches on each spin

Nolimit Bonus 

Nolimit Bonus provides an easy way to enter the bonus feature without trying your luck in the base game. Simply pay 68x or 1500x the stake to instantly trigger the Walk the Line or The Chair feature, respectively. There are also three lucky draw options with varying odds of triggering either of the features. They cost 82x, 355x, and 784x the bet


Ten paying symbols line up the paytable with the lower ones consisting of 10 to A card royals offering 0.3x to 0.9x the bet for five matching ones. As we proceed higher up the pay ladder, five inmates show up with payout values of 1x to 2.5x the stake for landing five identical symbols. 


Folsom Prison is a maximum security state prison in California. It’s the state’s second-largest prison, after San Quentin, and has overseen the execution of 93 condemned prisoners. 


Folsom Prison is a high-volatility slot. So be prepared to face a long dry spell before landing big wins.
