Slots With a Higher Maximum Win Than 100,000x

As you can see from our list, slots with payouts in excess of 50,000x are not uncommon now. And there is even a growing set of games with maximum wins in excess of 100,000x. Here we have reviewed 10 of our favourites, including Nolimit City’s new headliner, Tombstone Slaughter, with its sensational 500,000x top payout.

Top Win: 500,000 x
Reels: 6
Rows: Up to 3
Paylines: 324+
Release Date: January 28th 2025

It seems kind of fitting that Nolimit City have had to break their own highest max win slot record. After all they are in a league of their own when it comes to high max win, high volatility and crazy gameplay. And it’s no surprise that they haven’t just pipped Tombstone RIP’s 300,000x to the post, they’ve smashed it into touch as Tombstone Slaughter comes in with a 500,000x top payout and a suitably crazy 1 in 189m chance of hitting it!

The storyline in Slaughter is a continuation from Tombstone RIP as the daughter of El Gordo, who was hanged in the original, seeks vengeance on the town, burning it down in the process and taking out whoever she sees fit to. Of course, along the way the game is stacked with features like xNudge Wilds, xSplits, Infectious xSplits and Boothill Multpliers of up to 999x. Any chance of getting close to that 500,000x payout will come via one of two free spins rounds – Massacre Spins or Slaughter Spins.

Check out the NLC fan site page for more on this game and big win videos when they drop. And if you dare set foot back in Tombstone again, be ready for a tight-as-hell 9.39% hit frequency and, of course, insane volatility.

How Is The Maximum Win of a Slot Game Verified?

When online slots are created, a developer simulates billions of test spins to verify the return to player (RTP) and the maximum win potential of the game. The developer will usually round down the maximum win to an easily marketable value once testing is complete and maximum payouts from the game will be capped at that figure.

In the UK, the figures for RTP and maximum payouts are also verified by approved 3^rd party testing houses like eCorga. This is according to regulation set out by the UK Gambling Commission whose role it is to ensure gambling is fair and safe in this country. Testing houses will also verify that the results of every spin are completely random.

You can usually find the maximum win potential either on the game information screen available once you load up the slot, or on the developer’s website. For example, you can find the maximum payouts of all Nolimit City slots on their company website here.

What Are The Odds of Winning The Maximum Payout In A Slot?

It is true that you really can win these massive sums from a single spin playing the games on this page. But of course, these are very, very rare events. Most studios don’t publish the results of testing. But Nolimit City do. And they show on their website how many simulated spins it took to trigger the maximum win.

Here are some examples:

Slot Game	Maximum Payout	Number of Simulated Spins To Trigger Win
Tombstone RIP	300,000x	1 in 130,000,000 spins
Serial	74,800x	1 in 12,000,000 spins
Folsom Prison	75,000x	1 in 6,500,000 spins
Mental	66,666x	1 in 18,000,000 spins
Disturbed	54,391x	1 in 10,000,000 spins

* Data taken from Nolimit City’s own game profile pages.

The odds might look crazy but don’t think that means it can’t be done.

Every month, 100,000s of spins are being played out on these slots, and before long most will unleash one of their maximum wins. For example, click here to watch a big win video of a 300,000x on You Tiube.

Are High Maximum Win Games Always High Variance?

It is generally true that games with an unusually high maximum win like the ones on this page also have a very high volatility rating. High variance games display a very uneven win distribution with small numbers of high value wins rather than lots of smaller value wins. Volatile games are designed to unleash combinations of features, particularly in the bonus rounds, which trigger one another and may eventually lead to super big wins. It’s all about drama and high risk. Most low variance games have maximum wins of 1,000x or lower.

Which Are The Best Slot Sites to Play These Games On?

The games in our list can be found at most UK casinos but in particular we recommend the following ones which have the widest slots selections and have scored highly in our testing and review process.

Dominic’s first favourite slot was undoubtedly Barcrest’s Rocky, on the Fixed Odds Betting Terminals of William Hill circa 2008. In more recent times, he’s developed a love for rock music titles, like ZZ Top Roadside Riches, Danger High Voltage and Rasputin Megaways.

As a fan of dark and distasteful humour, he also has a lot of respect for Nolimit City’s apparent commitment to causing as much controversy as possible. On the other hand, traditional Asian slots, such as those stuffed with dragons, pandas and portly Chinese men, are not his cup of tea.
