Nolimit City is a slot studio based in Stockholm, with additional hubs in Malta and India (Racing Post). It is known for high-volatility slots and for its “x” mechanics, such as xWays, xNudge and xSplit (SiGMA; Gaming Intelligence). Evolution announced a deal to acquire the studio in June 2022 (iGaming Business) and completed it on 8 August 2022 (Evolution release).
📌 How to read this page: the figures below are the published defaults from the sources named on each review. Casinos can run other RTP versions of the same slot, so check the game’s info screen where you play. A maximum win is a ceiling, not an expected result.
| Slot | Published RTP | Max Win | Volatility (as rated) |
|---|---|---|---|
| Tombstone RIP | 96.08% (94.08% also offered) | 300,000x | High to Insane |
| Mental | 96.08% (94.2% may be offered) | 66,666x | High to Extreme |
| San Quentin xWays | 96.03% (94.11% listed) | 150,000x | High to Extreme |
| Fire in the Hole xBomb | 96.06% | 60,000x | High to Extreme |
Not a ranking. Each figure comes from two published sources, listed on the review page; where the sources rate volatility differently we show the range.
We do not rank them. Our reviews cover Tombstone RIP, Mental, San Quentin xWays and Fire in the Hole xBomb, with published RTP, max win and volatility ranges from two sources each.

High-volatility slots and its “x” mechanics such as xWays, xNudge and xSplit. The studio is based in Stockholm and has been owned by Evolution since August 2022.
Nolimit City is based in Stockholm, with additional hubs in Malta and India (Racing Post). Published profiles disagree on the founding year, so we do not state one. Evolution agreed to acquire the studio for an upfront EUR 200 million plus earn-outs of up to EUR 140 million (iGaming Business) and completed the deal on 8 August 2022 (Evolution release). We do not state a catalogue size or an average RTP, because we have not found a source we can cross-check.

On our pages Tombstone RIP and Mental both list 96.08% as the published default, with Fire in the Hole xBomb at 96.06% and San Quentin xWays at 96.03%. The differences are small, and casinos can run lower versions, so the number on the info screen where you play is the one that counts.
Supported coins differ by casino and can change. Check the cashier before you deposit.
Availability differs by casino and can change. Check the lobby and the cashier of the partner casinos listed on this page before you deposit.

RTP (Return to Player) is the theoretical percentage of wagered money returned to players over millions of spins. A 96.5% RTP means for every $100 bet, $96.50 returns on average. This is a long-run mathematical average — individual sessions vary enormously due to volatility. High volatility means bigger variance: more losing sessions but bigger wins when they occur. Low volatility means more consistent smaller wins.
Operators can choose between certified versions of a slot, so the same game can run at different RTPs at different casinos (CUNY Pressbooks; Track360). We have not checked which version each casino runs. Read the RTP on the game’s info screen and check the casino’s licence before you deposit.
Deposits here are almost always made in USDT on TRC20. The appeal is stability rather than speed: a stablecoin balance does not move with the market, so your bankroll reflects your play and nothing else. Deposit time and fees depend on the network and the casino, so check them in the cashier before you send anything. See our TRC20 explainer and the step-by-step deposit guide.
