Nolimit City slots
Nolimit City slots are the extreme-volatility games behind Tombstone, San Quentin, Mental and Fire in the Hole, built around the studio's xWays, xNudge, xSplit and xBomb mechanics. Evolution agreed to buy the studio in June 2022. Here is how its games work, what their 96% RTPs and huge caps mean in pounds, and which UK rules apply.
Key takeaways
- Nolimit City is Malta-registered, with teams in Sweden, Malta and India, and has been part of Evolution since a deal announced in June 2022.
- Most of its games sit at about 96% RTP in their default version, but lower versions exist, so check the help screen.
- Published caps are among the highest in UK lobbies: 500,000x on Tombstone Slaughter and 300,000x on Tombstone RIP.
- Volatility is rated High, Extreme or Insane, so typical sessions lose more than the average and big wins are very rare.
- Feature buy-ins are not offered to British players, and the £5 or £2 slot stake limits apply.

Nolimit City: the studio and its owner
Nolimit City was co-founded by Jonas Tegman and has its registered office in St Julian's, Malta. By 2022 it had teams working in Sweden, Malta and India. That year Evolution announced a deal to buy it for up to €340 million, made up of €200 million upfront and up to €140 million in earn-outs, and Evolution's own timeline (opens in a new tab) lists Nolimit City as a 2022 acquisition.
That puts Nolimit City in the same group as NetEnt, Red Tiger and Big Time Gaming. The contrast with NetEnt is striking: where NetEnt made its name with gentle games such as Starburst, Nolimit City built a following on dark themes, harsh volatility and caps in the hundreds of thousands. Our slot providers hub compares the full range of studios.
How Nolimit City's xMechanics work
The studio's brand is a set of modifiers with an x in front. Details change from game to game, so the help screen is the final word, but the core ideas are consistent. Our dedicated xWays and xNudge guide goes deeper.
| Mechanic | What it does | Example game |
|---|---|---|
| xWays | Reveals several matching paytable symbols in one position, adding ways to win on that spin | Mental II reveals 3 of the same symbol and raises the reel height |
| xNudge | A wild that nudges to fill its reel, adding 1 to its multiplier for each cell it moves | El Paso Gunfight uses sticky xNudge wilds in its free spins |
| xSplit | Splits standard symbols on other reels into two, doubling their count | In Mental II the xSplit itself turns into 2 wilds |
| xBomb | Clears all non-winning, non-bonus symbols so the rest drop and new ones fall in | Fire in the Hole xBomb |
| xBet | An option that raises the chance of triggering bonus features | xWays Hoarder 2 (January 2025) |
xBomb works like a cascading reels system, and xSplit is a form of split symbol. The trade press report on xWays Hoarder 2 (opens in a new tab) describes how xSplit there doubles symbol multipliers and how xBet lifts the feature chance. Whether an option such as xBet appears in a UK build depends on the game, so check the paytable.
The common thread is multiplication. A wild that nudges three cells has its multiplier raised by 3; an xSplit doubles a symbol count; xWays adds rows. When several stack on one spin, the totals climb very quickly, which is exactly why the studio can publish caps that dwarf most slots while keeping RTP near 96%.

Nolimit City series: how the sequels raised the caps
Nolimit City returns to its biggest hits, and each sequel has pushed the published ceiling higher while the default RTP has barely moved. That tells you the extra top-end potential is paid for by making smaller wins rarer, not by returning more overall.
| Series | Earlier game | Later game | Change in cap |
|---|---|---|---|
| Tombstone | Tombstone RIP, 300,000x (2022) | Tombstone Slaughter, 500,000x (2025) | +200,000x |
| San Quentin | San Quentin xWays, 150,000x (2021) | San Quentin 2, 200,000x (2024) | +50,000x |
| Mental | Mental, 66,666x (2021) | Mental 2, 99,999x (2025) | +33,333x |
| Fire in the Hole | Fire in the Hole xBomb, 60,000x (2021) | Fire in the Hole 3, 70,000x (2025) | +10,000x |
Fire in the Hole 2 (2024, 65,000x) sits between the two, and the later games use a Lucky Wagon bonus in the hold and win style. Our Tombstone series page and Fire in the Hole series page follow each family in detail. In September 2022 Nolimit City released The Border, which its co-founder Emil Svärd called the studio's first cluster game, with five or more touching symbols needed for a win.
What Insane volatility means for a £20 budget
A 96% RTP sounds the same on a Nolimit City game as on a gentle classic, and the average cost really is similar. What differs is how that average is made up. On an extreme slot, a large share of the 96% comes from rare, enormous wins, so the money returned in ordinary sessions is far lower than 96p in the pound. The average is pulled upwards by results most players never see.
| Stake | Spins from £20 with no wins | Average cost of 200 spins | Max win at this stake |
|---|---|---|---|
| 10p | 200 | 80p | £50,000 |
| 50p | 40 | £3.99 | £250,000 |
| £1 | 20 | £7.98 | £500,000 |
| £2 (18–24 limit) | 10 | £15.96 | £1,000,000 |
Read the table in two directions. The average cost per 200 spins is modest at 10p. But a £20 budget only covers 200 spins if returns keep topping it up, and on an Insane-rated game the base game often pays little. In practice that means many £20 sessions end well before 200 spins. The cap at the right is the absolute ceiling, reached in a minute share of play. Our guides to volatility and high against low volatility explain the difference between average and typical.
No pattern, timing or bet size changes a Nolimit City game's RTP. Every spin is independent, and a long dry spell does not make a feature due.
Nolimit City RTP versions and how to check them
Nolimit City supplies most titles at several RTP settings. San Quentin 2 is published at 96.13% with 94.03% and 92.11% versions, Dead Canary at 96.02% with 94.12% and 92.11% versions, and Misery Mining at 96.09% with a 94.05% version. On £1 spins, 96.13% costs about 3.9p a spin on average and 92.11% about 7.9p, so the lowest version roughly doubles your expected loss.
- Open the game and tap the menu or information icon.
- Find the game rules or paytable page and scroll to the RTP statement.
- Compare the figure with the default in our table: if it is two or four points lower, you are on a reduced version.
- Decide whether to play at that price or look for the same game elsewhere at a higher setting.
- Set your stake and session budget before you spin, using the casino's deposit limit tools.
Our question page on why the same slot has different RTPs explains how operators choose.
UK rules for Nolimit City slots online
Nolimit City is known internationally for bonus-buy menus, but UK players will not see them. Since a Gambling Commission warning in January 2020, feature buy-ins are not offered to British players; the Commission's games warning for online operators (opens in a new tab) said they risked breaching its standards on game rules and chasing losses. Our bonus buy page covers how this works.
- Stake limits: £5 a spin at 25 and over, £2 at 18 to 24, set out in the Commission's stake limit guidance (opens in a new tab) and our slot stake limits page.
- Speed: at least 2.5 seconds between spins, with no turbo or slam-stop.
- No autoplay: every spin needs a fresh press; see our autoplay ban page.
- Honest celebrations: a return equal to or below the stake must not be presented as a win.
- On screen: net spend and time played are shown during the session.
Are Nolimit City slots right for you?
Advantages
- Default RTPs cluster around 96%, in line with mainstream slots
- Distinctive mechanics that make each spin's outcome easy to follow
- Very high published caps for players who knowingly want a long shot
Drawbacks
- High, Extreme or Insane volatility means long losing runs are normal
- Lower RTP versions are common, so the price varies by casino
- Dark, violent themes will not suit everyone
These games fit a player who sets a small, fixed entertainment budget, accepts that most sessions lose it, and treats the cap as a remote possibility. If you want your money to last, a lower-volatility studio is the better match; our slots strategy page covers how to choose.

Frequently asked questions
Who owns Nolimit City?
Evolution owns Nolimit City, after announcing a deal in June 2022 worth up to €340 million: €200 million upfront and up to €140 million in earn-outs tied to performance. The studio keeps its own brand and its registered office in St Julian's, Malta, with teams in Sweden, Malta and India. It sits alongside NetEnt, Red Tiger and Big Time Gaming in Evolution's slot family. Our NetEnt provider page covers its best-known sister studio.
What is the biggest max win on a Nolimit City slot?
Tombstone Slaughter has the highest published cap among the Nolimit City slots we cover, at 500,000 times the stake. Tombstone RIP follows at 300,000x and San Quentin 2 at 200,000x. At a 10p stake, 500,000x would be £50,000. These caps are reached in a tiny share of play, and the games that carry them are rated Insane or Extreme for volatility. Our explainer on max win caps shows how to read the figure.
What does Insane volatility mean on Nolimit City slots?
Insane is Nolimit City's top volatility label, meaning returns are concentrated in very rare, very large wins. The RTP is still around 96% in the default version, but most of that comes from outcomes few players ever see, so a typical session loses more than the average figure suggests. Base-game wins tend to be small and infrequent. It is a label for players who accept that most sessions lose. Our volatility guide explains the maths.
What is xWays in Nolimit City slots?
xWays is a Nolimit City symbol that reveals several matching paytable symbols in a single reel position, which raises the number of ways to win on that spin. In Mental II, for example, it reveals three of the same symbol and expands the reel, and if more than one xWays lands they all show the same symbol. It changes how wins form, not the game's RTP. Our xWays and xNudge guide covers the mechanic in full.
Can you buy bonuses on Nolimit City slots in the UK?
No, bonus buys are not available on Nolimit City slots at UK-licensed casinos. Since a Gambling Commission warning in January 2020, feature buy-ins are not offered to British players, because the Commission said they risked breaching its standards on game rules and chasing losses. Versions sold elsewhere may show a buy menu, but UK builds do not. You reach the free spins only by triggering them in play. See our feature buy rules page.
What RTP do Nolimit City slots have?
Most Nolimit City slots have a default RTP between about 96.0% and 96.1%, such as Mental at 96.08% and Tombstone Slaughter at 96.01%. San Quentin 2 is a little higher at 96.13%. Lower versions are common, including 94% and 92% settings on games such as San Quentin 2 and Dead Canary, and the casino picks which one to run. Always read the figure in the game's help screen. Our RTP explainer shows what each setting costs.
Are Nolimit City slots good for beginners?
Nolimit City slots are a poor fit for most beginners, because their High, Extreme and Insane volatility ratings mean long losing runs and rapid budget swings. The mechanics are clear once learned, but a newcomer can lose a session budget quickly before seeing a feature. Lower-volatility slots, such as NetEnt's Starburst, give a gentler introduction to how reels, paylines and RTP work. Our beginner's guide to casino games suggests better starting points.
Is Tombstone Slaughter available in the UK?
Tombstone Slaughter is a Nolimit City game released in 2025, and whether you can play it depends on each UK casino's lobby, so search the lobby or check with the operator. Where it is offered, the UK version follows British rules: no bonus buy, a £5 stake cap at 25 and over or £2 at 18 to 24, and at least 2.5 seconds per spin. Its default RTP is 96.01% with lower versions possible. See our Tombstone Slaughter review.
