Starting off hot, the first game we’ll be covering is the ultra-violent Tombstone Slaughter: El Gordo’s Revenge by Nolimit City. Set in the fictional town of Tombstone, this game sees you take the role of El Gordo’s daughter as you look to take revenge for the death and humiliation of El Gordo. While western-themed slots aren’t a rarity, this is one of the more violent titles I’ve seen. As you score progressively bigger wins, you’ll be shown scenes of eye gougings, scalpings, and murders.

While not for everyone, this is definitely a game that’ll get your heart racing. Bonuses come in thick and fast and can either be triggered by landing the right combination of symbols, or otherwise purchasing them through the bonus buy menu. Massacre the culprits and leave the town in flames to complete El Gordo’s revenge and score an absolutely crazy 500,000x payout.

While Nolimit City games are a lot of fun, their violent imagery means that they aren’t as widely available as other slot games. Fortunately though, demand for them is growing amongst sweepstakes casinos. And through MyPrize, you can get started with a no deposit bonus through a Wheel Spin.

It’s back to the town of Tombstone with another Nolimit City game in Tombstone RIP. But this time, you’re playing the role of the law as you look to oversee the hangings and humiliation of Tombstone’s criminal underbelly. And speaking of hangings, there are a lot of them in this game. That means again that if you’re squeamish, you’ll probably want to skip over this one.

The big bonus of this one is the boothill free spins, which will see a new set of random high paying symbols become wild and gain access to multipliers for each of your free spins. While typically the multiplier and wild modifiers go to different symbols, they can be attached to the same symbol — and it’s this feature that’ll give you the best chance at scoring the 300,000x max win.

Like its sequel, Tombstone RIP can be tricky to find at sweepstakes casinos. Though one site you’re guaranteed to see it at is SpeedSweeps.

The sequel to one of the most popular US slot games is also responsible for handing out some of the biggest potential wins. Starburst XXXtreme largely uses the same gameplay as its predecessor. However, it comes with a massive change. As while the wild symbols still expand and award free respins whenever they land on the reels, in Starburst XXXtreme, each of these wild symbols now also have a multiplier of up to 150x attached to them.

And if you’re able to line up a couple of big multipliers together, you’ll have the recipe to scoring massive wins up to the potential max payout of 200,000x your stake.

While there are a couple of sweepstakes casinos that stock this game, my pick of the bunch is LoneStar. As when you sign up to them through our links, you’ll get access to a no deposit welcome bonus of 100,000 GC + 2.5 SC.

Taking place in the gritty San Quentin prison, San Quentin 2: Death Row is a game that doesn’t beat around the bush. Rap sheets involving torture, murder, and terrorism are shown. And while it may not be as gruesome as other Nolimit City games, there’s nevertheless still a certain unfiltered feel to the game.

Bonus symbols are the key to big wins in this game. When three or more are collected, you’ll score free spins — though even when there aren’t enough to earn free spins, they’re still not wasted as they’ll transform into wild symbols.

Before your free spins begin, there’s a unique gamble feature available wherein you can gamble five free spins for the chance to gain access to special features. Or alternatively, gamble for the max win of 200,000x straight up.

However you play it, it’s a lot of fun. And by playing at Fortune Coins, you’ll be able to get started with a no deposit bonus of 650,000 Gold Coins + 1,000 Fortune Coins.

Developed by Relax Gaming, Money Train 4 is the fourth installment of the popular Money Train series of games. Using the familiar cowboy meets steampunk theme that the series is iconic for, Money Train 4 brings back all the classic features that you’d expect in any game with the Money Train name, but with an absolutely massive 150,000x max win.

Unsurprisingly, the money cart bonus rounds are where the biggest wins happen. And while rare symbols are your best bet for scoring big wins, you can also score some pretty hefty payouts with basic combinations like persistent payers and persistent collectors that play off each other to award increasingly massive wins the longer the bonus goes on.

Relax Gaming is a pretty popular developer, and so you should have no trouble finding them at most sweepstakes casinos. However, if you’re looking for a sure thing, we recommend SweepNext.

Once again, we’re back in Nolimit City’s San Quentin with San Quentin xWays. The bonus games are a little less extreme than in its sequel, as is the max win, which while still an absolutely massive 150,000x, is smaller than the 200,000x max win in San Quentin 2: Death Row. And to be honest, this one just seems to be missing that grit that you expect from Nolimit City.

In full transparency, I didn’t play San Quentin xWays until after I got hooked with its sequel — and so maybe I’m a little spoiled. However, compared to its sequel, I can’t help but feel that this game is a little unrefined. Rather than showing grimy rap sheets of the prisoners when you score big wins, this game instead shows a scene where you’re making it rain cash in a nightclub. And while cool, it doesn’t really fit in with the prison theme.

Of course, that’s just my opinion. And if you’re looking to check this game out for yourself, you can do so at RichSweeps.

If it ain’t broke, don’t fix it. Big Time Gaming knew they struck gold with the original Max Megaways — and so rather than mixing things up, they just bumped up the max win to 147,620x and kept things pretty much identical. And to be honest, that’s fine by me.

Classic megaways mechanics are in effect — meaning that while the number of reels will stay the same between spins, the amount of symbols that will land in each of these reels will change between spins. Similarly, the reactions feature is once again back. So whenever you score a win, winning symbols are removed from the reels and new symbols tumble in from above — giving you the chance to link wins together.

Unfortunately, unlike its predecessor, Max Megaways 2 can actually be a little hard to find at sweepstakes casinos. Fortunately though, one site that is guaranteed to stock it is WOW Vegas. And by signing up through our links, you’ll get 250,000 WOW Coins + 5 SC on signup.

• Max Win: 139,200x

It’s no secret that the biggest wins of Max Megaways come from the free spins feature. And that’s why when developing this game, Big Time Gaming made sure to offer multiple different routes to scoring free spins. Of course, you can enter the old-fashioned way by landing scatters. However, you can also choose to buy in directly, exchange a single big win for guaranteed entry, or gamble a medium-sized win for a chance to enter it.

Once you’ve entered your free spins, you’re free to select your modifiers. And from there, you’re all ready to go as you begin your hunt for the max win of 139,200x.

Truth be told, you’ve got a few options to choose from when deciding where to play Max Megaways at. Though in my opinion, if a game is offered by RealPrize, then that’ll usually be your best bet — and that’s exactly the case with this one.

With one of the most unique art styles around, Robin Hood: Nottingham Raiders immediately stands out when compared to other slots. But it’s not just appearance that makes this game one of a kind. Because as you play, you’ll discover a variety of unique mechanics seldom used in other games, like the use of the special wilds feature.

Unlike normal wilds, special wilds are collected in a special meter whenever they land. And once this meter fills, you’ll be given a free respin where all the wilds are released onto the reels at once. Even better though, if this feature occurs during free spins, then these wilds will become roaming wilds that roam the reels for the duration of your free spins — adding multipliers the more wilds there are in a reel, and helping to award wins of up to 121,500x.

Despite being one of the most popular games by Peter & Sons, Robin Hood: Nottingham Raiders is an exceptionally rare game to find at sweepstakes casinos. And in fact, the only site that I was able to confirm that does actually stock this game is Stake.us.

Veteran players will only need one look at this game to see its similarities to Money Train 3. But don’t worry. It’s not a rip-off — and Great Western 3 is also provided by Relax Gaming, and is in fact the exact same game as Money Train 3, though just rebranded.

So when playing this game, you can expect the money cart bonus rounds as well as the same bonus symbols. And most importantly, you can expect the same 100,000x max win.

Truth be told, you can actually find Money Train 3 itself at sweepstakes casinos. However, if you want to play it at our recommended sweepstakes casino of McLuck and take advantage of the no deposit welcome bonus of 7,500 GC + 2.5 Free SC, it’ll be under the title of Great Western 3.
