San Quentin Review

San Quentin slot review Share on Facebook

January 10 2021 by Casinogamesonnet

Developed by Nolimit City, San Quentin is a five-reel slot that can offer up to 46,656 ways. It focuses on the infamous California state prison of the same name.

With menacing prisoners, shanks, and even the threat of shower-room rape, San Quentin is one of the most-controversial slots of all time.

But does it have substance beyond the shock value? You can find out below as we review everything that San Quentin slot offers regarding gameplay, win potential, features, and more.


This five-reel slot features 243 ways by default. However, the number of ways can expand to 46,656 in the bonus (covered later).

You need to land 3+ matching symbols in adjacent reels to win. All winning combinations must start in the first reel and move left to right.

Regarding the atmosphere, Nolimit City has chosen one of the world’s most-notorious prisons for this game. Established in 1852, San Quentin features California’s only death row for male prisoners. It also houses some of the state’s most-dangerous inmates.

That said, Nolimit couldn’t just take a playful approach to this game. Instead, it has pulled out all filters by offering a gritty representation of San Quentin State Prison.

If you’re looking for a light-hearted atmosphere, then this game isn’t for you. San Quentin takes place outside the barbed-wired gates of the penitentiary.

You’ll see guard towers and loudspeakers just over the gates. During the bonus round, you head to the rec area, where a basketball hoop and concrete walls await. You’ll also see a cutscene involving a shower room floor, two sets of feet, and a dropped bar of soap (make your own interpretations on this one).

San Quentin Max Win, Payouts and Symbols

The low-paying symbols don’t exactly show the softer side of prison. They include handcuffs, a lighter, shank, soap, and toilet paper.

High pays consist of some not-so-friendly inmates, including Beefy Dick, Biker Bill, Crazy Joe Labrador, Henrich the 3rd, and Loco Luis.

Beefy Dick pays the most among regular symbols by offering 5x your stake for five symbols. You can win up to a whopping 150,000x your stake when accounting for features.

San Quentin RTP, Volatility and Betting Options

The betting range runs from €0.20 and €32. An autoplay option lets you keep the reels spinning automatically for up to 100 rounds. You can set autoplay to turn off based on win/loss limits.

The San Quentin RTP is 96.03% by default. According to Nolimit City, 58.74% of the RTP is available in the base game and the other 37.29% comes from the bonus. However, you can raise the payback as high as 96.95% through the feature buy option.

Hit frequency sits at 34.25%. Nolimit rates the volatility at 10/10, which is brutal to say the least. Of course, the high volatility is expected when considering the 150,000x maximum prize.

San Quentin Features

San Quentin’s lucrative features are behind its immense win potential. You can look forward to Split Wilds, Enhancer Cells, and Lockdown Spins through this slot.

Split Wild Symbols

Split Wilds can randomly land anywhere on the grid. When appearing on a reel, they split all regular symbols into two on the respective reel. They, however, don’t split into two themselves. Thanks to these wilds, you’ll enjoy more ways to win in the base game and bonus.

Enhancer Cells

The grid begins with five reels and three rows (5x3). You’ll notice that the top and bottom positions of each reel are blocked off with bars.

The Enhancer Cells feature can unblock these positions. You trigger this bonus by landing 1-2 scatter symbols (prison tower) anywhere on the reels.

Triggering scatters turn into wilds and also increase the number of ways. They also open the blocked top and bottom position in their respective reel.

Once the cells open, they’ll offer one of the following special symbols/modifiers:

Lockdown Spins

You trigger Lockdown Spins by landing 3+ bonus symbols. You’ll receive 1, 2, or 3 Jumping Wilds (police badge) when unlocking this feature with three, four, and five scatters, respectively.

All Enhancer Cells positions are open for the entirety of the bonus. You’ll also benefit from a multiplier symbol as well. The number of free spins and multiplier are randomly chosen before this bonus starts.

As for Jumping Wilds, they jump around the grid to random positions during each spin. If one of these wilds lands on a Razor split symbol, then its win multiplier will double. The highest potential multiplier is 512x, which plays a huge role in reaching the maximum payout.

Feature Buy

You can automatically trigger Lockdown Spins by using feature buy at any time. This option requires spending a multiple of your stake.

You’ll receive more scatter symbols based on how much you spend. Here are the different choices:

Similar Slots to San Quentin

Nolimit City has a penchant for developing off-the-wall games. San Quentin easily falls into this trend and compares well to Nolimit’s Barbarian Fury, Punk Rocker, and Warrior Graveyard. Assuming you like slots on the rougher side, then you should appreciate all of these games too.

One area where San Quentin departs from these slots, though, is its win potential. You won’t find many games among Nolimit’s collection—or anywhere for that matter—that pay up to 150,000x your bet.

Final Thoughts

This game isn’t for the fainthearted in terms of theme or volatility. Based on its hardcore prison atmosphere, San Quentin is as gritty as it gets for an online slot.

It also features a 10/10 volatility rating, which will put you through some rough patches. However, this game is definitely worthwhile if you can handle the volatility and controversial subject matter.

It presents a totally unique theme that’s well-planned and perfectly designed. San Quentin can also deliver a fortune worth up to 150,000x your stake. You can win as much as €4.8 million with the max €32 bet.

Of course, winning the top payout is unlikely. But if you like dreaming while playing slots, then you’ll enjoy the wild win potential. More importantly, San Quentin provides a very entertaining cyber journey to a place that you’d, otherwise, never want to visit.
