About Nolimit City
Nolimit City was founded in 2013 and spent three years building its own engine before releasing anything, which is unusual and explains a lot about what followed. Oktoberfest arrived in 2016, the Malta licence came next, and distribution deals with Betsson, Kindred and 888 in 2020 put the studio in front of a mainstream audience for the first time.
Then came the games that defined it. Deadwood, San Quentin xWays, Mental, Tombstone R.I.P. and Fire in the Hole established a house style with no real precedent: prison yards, asylums, frontier violence, grotesque cartoon art, and maths tuned so far toward the extremes that a normal session produces almost nothing at all.
Evolution bought the studio in 2022. Unlike some acquisitions, the output did not soften. Mental II and the later releases pushed maximum wins higher still, and the studio’s registered licensing entities remain in Malta while it operates under its own name.

Those maximum figures are the largest in mainstream online slots, and they are the reason the studio gets played. What they are not is a description of what a session looks like, and the next section is where what a max win figure actually represents stops being abstract.
Mental
An asylum themed slot that stacks xWays, xNudge and xSplit together, rated 10 out of 10 on the studio’s own volatility scale. It hits something roughly once every three spins, which sounds generous until you see how small most of those hits are, and almost all of its value sits inside the bonus rounds.
San Quentin xWays
The prison yard slot that pushed the studio from cult favourite to industry name, built around xWays and the Lockdown Spins feature, with a standard RTP of 96.03%.
Tombstone R.I.P.
The frontier western with the largest maximum win in the catalogue at 300,000 times the stake, using xNudge wilds that add a multiplier for each position they move.
What Nolimit City Publishes About Mental
Most studios publish an RTP and a maximum win and stop. Nolimit City’s own affiliate game sheet for Mental goes considerably further, and these are its figures rather than anyone’s estimate.

💡 One in Eighteen Million, in Hours: Nolimit City says Mental’s 66,666x arrives about once in 18 million spins. At one spin every five seconds without a single break, that is roughly 25,000 hours of play, or more than a decade of eight hour days. The studio deserves genuine credit for publishing it, because almost nobody else does, and it reframes the headline number honestly: 66,666x is not a target, it is the outer edge of a distribution. The figures that will decide your actual session are the 96.08% return and the one in three hit rate, and if you want those three numbers separated properly, RTP, volatility and hit frequency are three different things.
Volatility and What a Session Really Looks Like
Nolimit City builds almost nothing calm. Mental carries the studio’s own 10 out of 10 volatility rating, and most of the famous titles sit at or near that mark.
The practical consequence is a session shape that catches people out. A one in three hit rate means the reels do pay regularly, but the overwhelming majority of those payments are smaller than the stake that bought them, so a balance drains steadily while the screen keeps flashing. Everything that makes these games worth playing is inside bonus rounds that arrive rarely.
Bonus Buys and Feature Prices
Buy features are fundamental to how these games are designed, and Mental’s run from 80x to 1000x the stake depending on which entry you choose.
- Cheaper entries buy the weaker bonus modes, so the price tracks the quality of what you get
- The most expensive entries buy the modes that produce the extreme results
- Buy prices are set by the studio, but availability is set by your market
Buy features are restricted or banned in several regulated markets, so the buttons may be absent even where the game is available. Our guide to how bonus buy slots price their features covers what you are actually paying for.
RTP Versions and the DX1 Build
Mental’s game sheet lists two builds, the standard 96.08% and a 94.20% version labelled DX1, and the studio assigns them separate game identifiers. The operator chooses which to run and nothing on screen distinguishes them.
Nearly two percentage points is a meaningful difference on a game this volatile, because a lower return on extreme maths means the quiet stretches get quieter rather than the wins getting smaller. The figure in the game information panel is the one that applies to your account, and why the same slot pays differently at different casinos explains how operators end up with the cheaper build.
Mobile and Game Performance
Nolimit City builds in HTML5 and its games run in a mobile browser without an app. They are heavier than most, with dense animation and layered sound, so an older phone will feel it on the busier titles. Connection quality matters less than device age here, which is the reverse of live dealer games.
Which Casinos Offer Nolimit City?
Wide availability across regulated European markets and very heavy representation at crypto friendly casinos, where the extreme volatility audience largely sits. The Evolution relationship has broadened distribution further since 2022.
The casino list on this page shows only operators that carry Nolimit City and accept players from your country. When comparing them, check:
- Which RTP build each casino runs, visible in the game information panel
- Whether bonus buys are available in your market
- Whether these games count toward bonus wagering, since extreme volatility titles are frequently excluded or capped
- The maximum bet permitted while a bonus is active, which matters more here than at most studios
- The operator licence and whether it is recognised in your jurisdiction
Are Nolimit City Slots Fair?
Nolimit City holds a Malta Gaming Authority B2B licence and its games are certified for regulated markets, which means the random number generation and the published maths are independently tested before release.
These games attract accusations of being rigged more than almost any others, and the reason is the session shape rather than anything wrong with the software. A certified game returning 96.08% with its value concentrated in a one in eighteen million event will produce long, brutal runs, and that is the approved behaviour rather than a fault. What certification covers and what it does not is set out in our guide to how RNG certification and testing labs work.
✅ A Studio That Publishes Its Own Worst Numbers: Nolimit City prints the 1 in 18 million figure, the 10 out of 10 volatility rating and the existence of a 94.20% build in a document it hands to affiliates. None of that flatters the games, and most studios publish none of it. That transparency is the strongest argument for trusting what these games claim, and it also means a reader who feels misled by a Nolimit City slot was told the truth in advance by the studio itself.
Nolimit City Compared to Other Studios
Compared to Hacksaw Gaming, these two are played by the same people and often confused. Hacksaw is more consistent on return and considerably better on older phones. Nolimit pushes maximum wins several times higher and publishes far more about its own maths.
Compared to Pragmatic Play, the gap is deliberate. Pragmatic’s biggest games stop around 21,000x and are built for the widest possible audience. Nolimit City’s start where Pragmatic’s finish and are built for a narrow one.
Compared to its Evolution stablemates, NetEnt and Red Tiger sit at the opposite end of the same group’s catalogue, with low volatility classics and modest payouts. One company now owns both extremes.

Who Nolimit City Suits, and Who Should Walk Away
These games suit a player who understands what a one in eighteen million outcome means and wants to play anyway, with a bankroll sized for hundreds of empty spins and no expectation that a session will break even. Played that way they are the most distinctive slots available.
They suit nobody who is trying to clear a wagering requirement, nobody playing a balance they need back, and nobody who reads a 300,000x figure as a realistic aim. If the appeal is the maximum win rather than the ride, the arithmetic above has already answered that. And if you do intend to chase one, it is worth playing where a large win actually gets paid quickly, which is what our list of the fastest paying casinos is for.
