Top 5 Most Popular Merkur Slots 

Merkur Gaming mostly create land-based slot machines for their German and European casinos. However, they do also produce online slot games that players can enjoy, as well as digital versions of their physical machines.  

Let’s break down 5 of their most popular titles available online and explain their main features and mechanics.  

221b Baker Street 

Merkur Gaming’s 221b Baker Street is a shadowy interpretation of the Sherlock Holmes versus Moriarty mysteries, played on a 5x3 setup with up to 20 paylines. 

You can earn up to 10,000x your bet by finding 5 Sherlock Wild symbols, and trigger 2 bonus rounds: 

• Big Ben Feature: 3+ Big Ben Scatters award you with 2-20 free spins and a 1x-5x multiplier 

• Duel Bonus: 3+ Duel Symbols cause prizes to appear on the reels. Any shot by Holmes can be claimed, but prizes shot by Moriarty disappear 

Black Hole  

Black Hole is a unique title in Merkur’s portfolio, featuring a high-risk, high-reward Pays Mechanic, perfect for players looking for an exciting new challenge.   

In this game, wins are not paid immediately. Instead, each win fills a number of prize towers. The more you win, the more you can cashout from these towers, with a max prize of 1,000x your bet.  

You can collect all or part of your winnings after each spin, but if you land a Black Hole Symbol, the towers get emptied and you lose all uncollected winnings.  

Coffee House Mystery 

Coffee House Mystery continues Merkur Gaming’s habit of simple slots with exciting pay mechanics.  

There are 4 Expanding Wild symbols, which diversify how you can earn wins by expanding in different ways. Additionally, the game has a Triple Clue bonus round, triggered with 3 Diamond Scatters.  

You start the round with 10 free spins, which you can retrigger by landing more Scatters. When you do, a second set of 5x3 reels is unlocked. You can have up to 3 Pay Windows in this mode, significantly increasing your chance of activating paylines.  

Fruitinator Wild 

We think fans of retro slot games will love Fruitinator Wild’s nostalgic design and easy gameplay. With a 5x3 setup and 20 fixed paylines, winning symbols randomly expand for a chance at activating more paylines.  

However, this game’s biggest feature is the Adjustable Volatility. If you play on the Hot setting, you have a higher chance of symbols expanding, while playing on Extra Hot raises the volatility and makes high value wins more likely. 

Ghost Slider 

Our final recommendation is Ghost Slider, an eerie 5x3 slot with yet another innovative take on a classic mechanic.  

This game uses a Cascading Reels feature to trigger a bonus game. If you get 4 or more consecutive wins in a round, you earn up to 50 free spins.  

On top of that, your chances of chaining wins together are helped by 3 Wild Symbols, which can fill in for all the other symbols on the reels.  

About Merkur Gaming

Merkur Gaming has a long-standing history within the gambling industry, with decades of experience producing top-quality games.  

This is evident in their approach to slot design, where simple mechanics are reanimated through innovation and creativity.  

To learn more about Merkur Gaming as a company, let’s take a look at their history and accomplishments.  

Company History 

In 1957, a German man named Paul Gauselmann began a business installing jukeboxes at local restaurants. He quickly found success and expanded his operations to include arcade games. 

By 1974, Gauselmann opened his first gaming venue in Delmenhorst, alongside a flagship slot machine called Merkur B. The booming success of this pairing set the Merkur Group on a path to international recognition.  

By 2025, the company has grown beyond Germany, with brick-and-mortar casinos popping up across Europe. They have also conquered the online gaming scene with digitized versions of their most popular machines.  

Why Choose Merkur Games? 

Merkur Gaming has been developing casino games for decades, and the level of expertise that they bring to their titles is evident.  

Across the board, Merkur slots do a fantastic job of incorporating creative mechanics or payout methods into otherwise straightforward games.  

This allows them to produce titles with recognizable foundations for newer players, that are still unique and exciting enough to attract veteran gamblers.  

What Types of Games Does Merkur Gaming Develop? 

Merkur has a diverse gaming portfolio. Their land-based machines tend to feature mythological and fantastical themes, with an abundance of Egyptian-focused slots on offer, such as Legends of Anubis or Pharaohs Rising. 

Their online portfolio, however, is somewhat different, focusing more on mysteries and strange occurrences, such as 221b Baker Street or Ghost Slider respectively. They also create several retro-inspired games with classic fruit, bells, and lucky 7 symbols. 

Beyond casinos, Merkur Gaming has also expanded into Sports Betting, offering you the chance to bet on your favorite events, whether you’re into football, racing or even e-sports.  

Awards Won by Merkur Gaming

Merkur’s popularity across Europe has helped them get credited as a leading company in iGaming, technology, and human resources.  

In 2023, the Global Regulatory Awards honored the group with the Compliance Team of the Year award for their dedication to fair and legal gambling. 

They have also been recognized for their technological prowess with CHIP Magazine’s Digital Innovator award in 2022, and for their human resources team, earning themselves the 2025 Leading Employer award for ranking in the top 1% of German employers. 

Merkur: Licenses and Regulations 

As the Merkur Group covers many areas within the iGaming industry, they are licensed to operate in many jurisdictions by multiple regulatory bodies.  

Their main authority is the UK Gambling Commission (UKGC), where they have several licenses covering their land-based operations and technical developments.  

They also carry an active license from the Malta Gaming Authority (MGA) covering their bookmaking services and online gaming platform.  

Other Providers to Explore 

For as decorated as Merkur Gaming is, if you’re looking for a varied gaming session, you may want to explore games from other top game developers in the industry as well.  

With that in mind, here are 5 of our personal favorites, known for delivering high-quality and innovative online games.  

Pragmatic Play 

Topping our recommendations is one of the industry leaders: Pragmatic Play. 

With hundreds of games in their library, this developer has a reputation for delivering outstanding titles with a variety of themes and mechanics, making them an accessible provider for many types of players. 

If you enjoy simple slots, you can check out their popular title Gates of Olympus, or Gates of Olympus 1000 to chase higher prizes. Or if you prefer higher-stakes options, you can hunt for one of 5 jackpots in Jackpot Blaze.  

Other Pragmatic Play games include: 

• Sugar Rush 1000: featuring round multipliers and a 25,000x max win 

• The Dog House Megaways: with 117,649 ways to win 

• Dragon Gold 88: with stunning visuals and a 5,000x max win 

Evolution Gaming 

Our second recommendation is Evolution Gaming, another highly respected provider, especially among live casino players. 

Their Gameshow library is unmatched, featuring iconic names like Crazy Time and Monopoly Live. Evolution Gaming also allows you to enjoy demo versions of these shows with their First Person adaptations.  

If gameshows aren’t your thing, this provider also excels at table games such as Blackjack First Person, and has plenty of slot options, such as Gonzo’s Quest, produced by their subsidiary NetEnt.  

Other Evolution Gaming titles include: 

• Lightning Roulette: where random numbers on the wheel gain multipliers 

• Mega Ball: which is a high-stakes version of Bingo 

• Dragon Tiger: which is a similar to Baccarat 

Relax Gaming 

Relax Gaming is a popular provider among casino players who enjoy chasing jackpots.  

This is thanks to their incredibly successful Dream Drop series, where you can hunt for 6 jackpots and up to €2,000,000 in Bill & Coin Dream Drop, Space Miners Dream Drop, and many others.  

If you’re not a slot player, Relax Gaming also produces a number of table games, such as Blackjack Neo or Roulette Nouveau.  

Other Relax Gaming titles include: 

• Fang’s Inferno: where you choose which bonus round to play 

• Temple Tumble: where the number of symbols changes with every spin 

• Galactic Racers Dream Drop: with futuristic visuals and a 10,000x max win 

Nolimit City 

Nolimit City specializes in creating provocative slots with darker themes and highly engaging mechanics. Their most popular titles include Mental and its sequel Mental 2, and their San Quentin jailhouse series.  

However, this provider is best known for their innovative gameplay features, with many titles including xWays or xNudge mechanics that increase your chances of landing wins. 

If you don’t enjoy edgy themes, Nolimit City also produce lighter titles like Owls and Starstruck which may be more suitable.  

Other Nolimit City games include: 

• Fire in the Hole 3: with Expanding Reels and several bonus rounds 

• Tombstone Slaughter: where you can earn up to 500,000x your bet 

• Duck Hunters: featuring Cascade Multipliers up to 1,024x per symbol 

Yggdrasil 

Slot games themed around mythology aren’t exactly rare, yet Yggdrasil still manages to excel in this field. Their Vikings Go series, featuring titles like Vikings Go Berzerk and Vikings Go To Hell are fan favorite titles, as is their Valley of the Gods series. 

Like Nolimit City, Yggdrasil’s unique gameplay technology is what truly sets them apart, with bespoke mechanics helping you achieve wins.  

If you’re looking for slot games with features unlike any other, we think Yggdrasil titles are an excellent place to start.  

Other Yggdrasil titles include: 

• FruitPunk: with futuristic graphics and a 7,000x max win

• Shipwrecked: with a unique take on Cluster Pays mechanics

• Ghost Father: where special symbols unlock different bonuses
