Covers the studios that build for the big max win, and the Megaways and new-release rankings.

This page carries figures checked on the date above, and that window has now passed. Studios publish new RTP settings and casinos change their rules: re-check the sources at the foot of the page.
A max win is a ceiling. It's the most the game's maths will pay on a single spin or bonus round, written as a multiple of your stake. It isn't a target, and for almost everyone who ever plays these games it never comes anywhere near.
How rare? Studios rarely publish the odds. Nolimit City does for Mental: its 66,666x max win has a probability of 1 in 18 million. If you managed 1,000 spins an hour, non-stop, that's 18,000 hours on average to see it once. And that probability is part of the RTP, so the money that funds the ceiling comes out of everyday wins.
One more wrinkle. Push Gaming doesn't publish a cap. It publishes a "highest observed win", the largest win it has recorded on the game. That's a different thing, and three of the slots below use it.
This list sorts by max win alone. Read it as a list of the wildest games we score, because that's what it is.
At a glance
Top of the list
Tombstone RIP, 300,000x
What a max win is
The most a game can pay on one spin or round, not a likely outcome
How rare
Nolimit City puts Mental's 66,666x at 1 in 18 million
The catch
Every slot here is high or very high volatility; long losing runs are normal
Push Gaming figures
Highest observed win, not a published cap

The ranking
Every slot we scored, sorted by published max win, at most 3 per provider. Ties go to the higher Spin Score. Spin Score = 40% RTP, 15% max win, 30% free spins round, 15% base game. How we score
The biggest number in our data: a 300,000x cap. It comes with the lowest hit frequency we recorded anywhere, 9.08%, so roughly nine spins in ten pay nothing. xNudge wilds gain a multiplier with each nudge and splitting wilds double symbols. The second free spins round, Boothill, stacks multiplier wilds toward that cap, and Bigwinboard says buying it costs 3,000x. Nolimit City rates it Insane. 96.08% at best, with a 94.08% setting.

What it is: A western slot on 5 reels and 108 ways where xNudge wilds gain +1 multiplier per nudge and splitting wilds double symbols. Two free spins rounds raise the stakes up to a 300,000x cap.
Free spins round: Two free spins rounds, the second (Boothill) built around stacking multiplier wilds aimed at the 300,000x cap.
Base game: xNudge and splitting wilds appear, but the 9.08% hit rate means most spins pay nothing.

The 200,000x needs a caveat. It's the figure in NetEnt's launch material and on SlotCatalog; the netent.com stats box shows 16,800x. RTP is similar: 96.45% applies with the paid XXXtreme Spins option, and SlotCatalog gives 96.26% for the base game. There are no free spins, so the bonus scores 4, but expanding wilds with random multipliers up to 150x can land on any spin. XXXtreme Spins aren't offered in the UK.

150,000x, per Relax Gaming's own description, and the best Spin Score at that level, 8.3. The Money Cart bonus scores a perfect 10: it starts on 6x4, unlocks rows, and brings in the Arms Dealer, Upgrader, Unlocker and Reset. Max bet is just 6, so the ceiling in cash terms is lower than the multiple suggests. RTP 96.1% per SlotCatalog, and Relax lists a UK game ID ending _92.

Also 150,000x, placed just behind Money Train 4 on Spin Score. Enhancer Cells above and below the 5x3 reels open at random to add wilds, Razor Splits or xWays symbols. Lockdown Spins start with up to three jumping wilds and a multiplier convict. Nolimit City rates it High rather than Insane. Bigwinboard lists buys of 100x, 400x and 2,000x. RTP 96.03%, or 94.11% at the lower setting. Max bet is 32.

100,504x according to playin.com, Evolution's official site for Big Time Gaming, which also rates volatility 9.3 out of 10. The bonus offers two free spins types, and collecting Heartstopper symbols upgrades both. The base game is dry apart from Angel Wilds on the middle reels. The RTP range is narrow, 96.43% to 96.31%, which is unusual on this list and a point in its favour.

100,000x, but that's Push Gaming's highest observed win, not a published cap. It's also our top Spin Score overall, 8.7, so it's the strongest all-round game on this page. Free spins start at x1, x5 or x25 depending on scatters, and mystery stacks nudge to raise the multiplier. RTP 96.55% or 94.49%. Push Bet adds 10% to the stake. I'd leave that off.

NetEnt's Train Heist text says wins can reach 100,000x; the stats box on the same page shows a 1,600x max payout, and SlotCatalog lists 111,111x. We use the feature text. Train Heist is one of three free spins modes, all built on sticky wilds with multipliers up to 16x. The base game is plain 9-line play, scored 3. At 96.8% it has the second-best RTP on this list.

77,800x per playin.com, which rates the volatility a full 10 out of 10. The best RTP on this list, too, at 96.9%. Adjacent reels can clone into 3 to 6 identical reels on any spin, on up to 117,649 ways. The free spins aren't described by the studio, so our editors scored them a plain 5.

50,000x per ELK's data sheet, but the Spin Score is just 5.5, the lowest on this page. The reason is RTP: ELK lists only 94.0%, which scores the minimum on our scale. That's a shame, because the editors scored both the bonus and the base game 8: Nitro Boosters fire from two screens above the reels and Nitro Multipliers multiply each other. Great features, poor return.

Demo buttons open the free-play version on the game studio’s own site: no deposit, no account. We are not paid for them. How we make money
How this list is made
We sort our 105 slots by the max win in their record, highest first, break ties on Spin Score, and allow three per studio. The Spin Score still shows on every card, so you can tell the good games from the merely big ones. How that score is built is on how we score slots.
All fifteen hit 50,000x or more, which is the top of our max win scale. So in the Spin Score, a 300,000x game and a 50,000x game get the same 10 for max win. That's deliberate. Past a point, a bigger ceiling doesn't change anything you'll experience.
A cap, a description, or an observed win
Not every max win means the same thing, and the sources say so.
Nolimit City and ELK publish a figure on the game page or data sheet as the game's maximum. Relax Gaming puts it in the game description. Push Gaming publishes a highest observed win: the largest win recorded, which tells you what has happened, not what the maths allows.
NetEnt is the messy one. Its stats box shows a "max payout" that can disagree with its own feature text. Dead or Alive 2 shows 1,600x in the box and 100,000x in the Train Heist description. Starburst XXXtreme shows 16,800x in the box against 200,000x in launch material. We use the larger, feature-text figure and say so on the card.
How rare is a max win?
Rare enough to ignore when you decide what to play. Mental is the one game in our data where we have the studio's published odds, 1 in 18 million for 66,666x. Most studios don't publish any.
What you can see is the cost of chasing it. Tombstone RIP pays something on 9.08% of spins. Money Train 3 and 4 hit about one spin in five, per SlotCatalog. Games built around a huge ceiling spend most of their time paying little or nothing, because the maths has to save up for the rare monster. Every one of these 15 is rated high or very high volatility.
And the RTP doesn't change. A 300,000x ceiling on a 96.08% game still keeps 3.92% of all money staked, on average, over the long run.
Bonus buys and the big number
Twelve of these fifteen sell a bonus buy, and the prices are steep. Tombstone RIP's Boothill round is 3,000x the stake per Bigwinboard; San Quentin's top Lockdown buy is 2,000x. On some of them the bought bonus has a slightly higher RTP than the base game. It's still below 100%, and you're paying for one round at a time. I'd skip them. More on the bonus buy slots page.
What's missing, and why
Mental (66,666x) and Fire in the Hole 3 (70,000x) are big enough to make the list, but Nolimit City already fills its three places with bigger numbers. Misery Mining (70,000x) misses for the same reason, and so does Push Gaming's Big Bamboo (50,000x), behind three other Push games. All are on the high volatility page and their provider pages.
Pragmatic Play has nothing here. Its biggest in our data is Sweet Bonanza 1000 at 25,000x.
Frequently asked questions
What slot has the highest max win?
In our data, Tombstone RIP from Nolimit City, capped at 300,000x the stake. Starburst XXXtreme is quoted at 200,000x in NetEnt's launch material, though netent.com's stats box shows 16,800x.
What does max win mean on a slot?
The largest amount the game can pay on a single spin or bonus round, as a multiple of your stake. At a stake of 1, a 50,000x max win is 50,000. It's a ceiling, not a likely result.
Has anyone ever hit the max win?
Push Gaming's figures are, by definition, wins it has observed, so on its games someone has reached them. For capped games the studios don't publish how often it happens. Nolimit City gives Mental's max win a probability of 1 in 18 million.
Do big max win slots pay less often?
In general, yes. All 15 games here are high or very high volatility, and Tombstone RIP, the biggest, pays on only 9.08% of spins. A bigger ceiling has to be funded by fewer, smaller wins elsewhere.
Is max win the same as jackpot?
No. A max win is a fixed multiple of your stake set by the game's maths. A progressive jackpot grows from a share of players' stakes across many casinos, as on NetEnt's Mega Fortune. None of the games on this list is a progressive.
