The 4 Best Unexpected Slot Crossovers

Popular Slot Crossovers Players Love

Collaborations between brands are always exciting. It's like the best of both worlds, offering unique products and a fresh take on an old classic.

The most obvious example that immediately springs to mind is a soap that's actually recently been on TV: Corriedale, mashing up fan-favourite characters from both Coronation Street and Emmerdale in a one-off episode packed with twists.

How is this relevant? Well, while they are uncommon, collaborations aren't entirely unheard of in the slots world, whether it's through licensing their mechanics, iconic slot series, or other IP.

When two industry giants team up to produce a new slot game, you know they mean business, and there have been some slot crossovers in recent times that have completely come out of left field.

Here are four crossovers in the slots world that completely blew our minds. In the words of Team Rocket: “Prepare for trouble and make it double,” but in the best possible way. 

4 Fantastic Vikings Go Fishing

When you think of Vikings, you may typically think of Norse warriors invading villages, pillaging settlements, and leaving chaos and destruction in their wake. Certainly not something you'd associate with the peaceful pastime of fishing. 

Still, 4ThePlayer and Yggdrasil Gaming decided the world needed more peculiarity, combining two of the most well-known series in iGaming: 4 Fantastic and Vikings Go, to create 4 Fantastic Vikings Go Fishing.

Swords and fins align in this beautifully bizarre slot as the two studios combine their might with complementary features, such as Yggdrasil's Berzerk and 4TP's Big Game Fish and Shark features. All of this works together to create a graphically cohesive slot with a solid 12,500x max win.

This unexpected slot crossover proved so popular with players that the unlikely duo returned for a sequel set in the heart of the icy Nordic fjords – 4 Fantastic Vikings Go Ice Fishing.

Net Gains

Relax Gaming has built a lot of their brand on collaboration, with their Silver Bullet partnership program and aggregation platform, as well as their Dream Drop progressive jackpot system, which they've licensed to many other studios over the years. 

One brand they've consistently collaborated with is CasinoGrounds. If you're not familiar, they are the world's largest gambling streaming community. Together, the pair have created games like Iron Bank, Iron Bank 2, Beast Mode, and Net Gains, with more sure to come in the future. 

Now, we could have chosen any of these four slots, but we've picked Net Gains. One, because we always enjoy a fishing-themed slot with a good pun, and two, because it truly shows Relax's growth and adaptability.

While it features some of the same mechanics and characters from Beast Mode, it builds on the success and criticism of their first two collab games. Although this is less of a crossover and more a pooling together of ideas; we believe it still deserves a spot on the list.

Freak Show Revelation

Leaving behind anthropomorphic fishermen and choppy seas, we move onto something that's just as bizarre – and intentionally so, with Freak Show Revelation by Sneaky Slots. 

This newcomer has made a name for themselves in the past few months, merging with Evolution Gaming. As part of the broader Evolution umbrella, there's Nolimit City, who have recently licensed their trademark xMechanics to Sneaky Slots.

You see the start of this beautiful partnership in Freak Show Revelation, as xBomb makes an appearance on the grid, pulling off a hatrick with a max win potential of 13,000x.

This is literally a match made in heaven, since both studios thrive on the weird and wonderful, and we can't wait to see where they go next.

The Dog House Megaways

Now, this final entry is less of a traditional crossover and more of a licensing of a well-known product. We'll be honest – we were running out of ideas. 

Still, The Dog House Megaways would never have existed without Big Time Gaming lending their flagship mechanic to Pragmatic Play, so there is that.

Outside of BTG's own Bonanza Megaways, it's probably one of the most well-known Megaways slots ever made, and for good reason – setting many tails wagging with its max win potential of 12,305x bet.

It's a twist on the OG The Dog House, with the familiar features players know and love: the perfect pooches, free spins, sticky wilds, and multipliers, with the bonus addition of the Megaways mechanic offering up to 117,649 ways to win. 

This shows that even old dogs can learn new tricks, unexpectedly jazzing up the Pragmatic Play formula.

Final Thoughts

Just like our favourite episodes of certain TV shows, crossovers may be rare, but when they do land, they're always an instant hit.

By blending familiar mechanics, recognisable brands, or proven formulas, these collabs feel both fresh and intentional, all while reassuring players at the same time.

The success of the titles we've mentioned shows there's a real appetite for experimentation, where studios can pool together their strengths and step outside of their usual creative lanes. 

Hopefully, these games are just the beginning, because if more game developers are willing to join forces, the future of slots could be even more exciting.

Just imagine the scenes if Smokey the Raccoon from Hacksaw's Le series linking up with the Reel Kingdom‘s iconic bearded angler for a cheeky fishing session in a Big Bass Bonanza crossover.
