Boomerang Studios’ Sharkluck Holmes brings together a fantastic mixture of themes, sharks and the world’s most famous detective. How has this not been done already? This is then combined with high-quality graphics and animations and not one but three free spins bonus rounds. If medium volatility isn’t your thing then this real money online slot might not be for you, however, there’s plenty to love with this slot. One of my particular favourite features was the three different types of free spins, which really elevated the slot’s gameplay in my opinion.

Here are Some Screenshots I Took of the Game

It’s elementary my dear, and that element is water! Sharkluck Holmes fuses everyone’s favourite Victorian detective with everyone’s favourite tornado-loving killer fish, and who doesn’t like the sound of that? This is established in the fun characters based on marine life wearing Victorian garb. The wild symbol is Sharluck Holmes himself, a purple shark complete with a deerstalker hat and trusty magnifying glass in hand, or should I say in fin? With a wide, toothy grin dancing on his face and quite the crazed look in his eye, Sharkluck Holmes is something to behold. 

Our dapper detective is joined by the two highest-paying symbols: a very serious-looking walrus in a suit jacket and red cravat and a gormless fish in a hat smoking a pipe. The gormless fish is my personal favourite, as the little lad looks very silly indeed. These characters add a lot of whimsical charm to the game and make it totally unique and really fun.

Should You Play the Sharkluck Holmes Slot?

Yes, Sharkluck Holmes is a game about a shark detective with a potential mind palace, so everyone should play this game. Jokes aside, the theme was the first thing that jumped out to me and caught my attention instantly. This lighthearted and whimsical design really appealed to me and added even more fun to the action. The game boasts really high-quality graphics, with both the visuals and animations being very detailed and impressive. I found that this added more to my appreciation of the theme, as it provided way more humour to the slot.

Mechanically, Sharkluck Holmes is grand too. The game offers three different types of free spins, which provide not only a lot of variety to the gameplay but can be triggered with only one scatter symbol. This is as few scatter symbols to trigger free spins as I’ve seen in a game, and although it is randomised, this is very appealing as a bettor. 

With all that being said, there were a few things about Sharkluck Holmes that I didn’t quite like as much. The one that jumps to mind is the sound mixing. The sound effects were too loud for the quiet backing music and there is no way to change this. This led me to ultimately turn off the music entirely, as it was too jarring. The gameplay has medium volatility, which won’t be for everyone. Newer players tend to enjoy slots with a lower volatility, as these theoretically payout more than others. While Sharkluck Holmes isn’t a high volatility slot, it will hypothetically payout less frequently than slots with lower volatility.

Lastly, while I thought the visuals were grand, I thought the free spins background was quite bland. The game introduces a new background when you hit the free spins feature. However, this image has less colour and detail than the background during the base game and ultimately looks less exciting. This isn’t the effect that you want free spins to have, as this doesn’t reflect their exciting gameplay. 

  • 🎉 Unique and hilarious theme
  • 🎨 High-quality graphics
  • 🎰 Multiple types of free spins to win
  • 🔊 The mixing of the sound effects is jarring
  • ⚖️ Medium volatility won’t be for everyone
  • 🖼️ The graphics during free spins are less eye-catching

  2. Next, the casino will ask you to complete your personal information. Fill out all your details, such as name, email address and phone number.

  8. With that, you’re all set to go off and enjoy Sharkluck Holmes.

My First Moments Playing Sharkluck Holmes

When I first opened the game, the first things that jumped out at me were the game’s graphics and sounds. Whilst both have been produced to a high standard, I had some issues with both. However, I think the graphics add more to the slot than they take away. 

Impressive Graphics

As you can expect, it was the theme of the game that jumped out at me at first. This unique mixture of sharks and Sherlock was really interesting and fun. The game’s theme is backed up by high-quality graphics that fully immerse the player. The game’s background is of an ocean floor and sways back and forth with animated movement. Once free spins are activated, this changes to a different underwater scene that I liked less. It has a lot of greys, and while it was still illustrated to a high standard, it did look a little flat compared to the base game background. That being said, even this less interesting background is still done to a high standard and really adds something to the game. I was very glad to see this, as commitment to the bit is always needed to pull off such a wacky and unique theme.  

The Sound of the Baskervilles

The sound of Sharkluck Holmes was a little strange. I thought the backing music was grand, as it sounds like the theme tune of a mystery and is quite soft-sounding, so players won’t feel overstimulated by it after a few hours of gaming. The problem I had was that the sound effects of the game were much louder than the theme. This sound mixing issue meant that I wanted to turn the effects’ volumes down to be more balanced with the music, but there’s no option to turn individual elements down. As I mentioned earlier, you can turn off the music as soon as you open the game, but doing so feels like a shame when the backing track adds a lot of fun and immersion to the game.

Let's Talk About the Bonus Games You'll Find

Sharkluck Holmes includes some interesting bonus games and features. The strongest features are the three bonus rounds that can be triggered by the scatter symbols. To find out more about these games, you can check them out below or in the game’s paytable.

Wild Symbol

As previously mentioned, the underwater detective himself is the wild symbol. He appears as his happy self, wreathed in purple bricks, with the word ‘Wild’ spelt out in purple bubble writing. Whenever you find Sharkluck Holmes on the reels, he’ll substitute himself for any of the other symbols, except the scatter symbol.

Scatter Symbol

Sharkluck Holmes has three different types of scatter symbols. These are the words ‘Sharkluck Holmes’ in green, pink or yellow and feature either a turtle, shell or starfish in the top right-hand corner. If you hit one or more of these scatter symbols, they will trigger their corresponding bonus feature and have the chance to award you five free spins. The colour of the symbols determines which of the three different types of free spins you activate. 

Each free spins round has an additional mechanic attached to it. If you’re lucky enough to hit multiple different types of free spins, these will work in combination with each other. However, if you hit the contagious wild feature alongside the expanding wild feature, the expanding wild feature will activate first. You cannot activate the same feature twice, but you can earn the other features by hitting their scatters, which will trigger one to two more free spins with each scatter you hit.

Expanding Wilds Free Spins

First up is the green expanding wild free spins feature. When you hit one of these scatters, an animation will play where the green bag sitting on top of the reel will absorb the scatter symbol and trigger an expanding wild. This is the same process for the other two scatter features, but they activate their own mechanic. The green bag changes one wild on the grid into a full column of wild symbols, resulting in a potentially bigger win.

Win Multiplier Free Spins

Next is the red win multiplier free spins feature. When the red bag at the top of the screen absorbs this scatter, it will change the free spins win multiplier from 1x to either 2x, 3x or 5x. When you trigger free spins with this feature, all the wins are multiplied by whichever multiplier you originally won.

Contagious Wild Free Spins

Last is the yellow contagious wild free spins feature. When the yellow bag at the top of the grid collects this type of scatter symbol, it will change one of the four highest paying symbols into a wild if it touches a wild symbol in any way. 

Some Technical Considerations About Sharkluck Holmes

I dived into the icy waters of Sharkluck Holmes’ more technical aspects and found a few interesting mechanics. The game has a theoretical Return to Player (RTP) percentage of 96.01%. This is the theoretical amount of your funds that will hypothetically be returned to you after the slot for an extended period of time. At Irishluck, we recommend playing slots that have an RTP of 96% and above so that you can have a reasonable Expected Value (EV), so Sharkluck Holmes cements itself as one of those games. 

Sharkluck Holmes is a medium volatility slot. This means that the game will theoretically pay out less frequently than games with low volatility, but more so than games with high volatility. In accordance with slot-based theory, it should pay out medium amounts when compared to low volatility’s hypothetically lower payouts and high volatility’s larger amounts. 

Why Do I Think Sharkluck Holmes Stands Out?

Sharkluck Holmes stands out thanks to its hilarious theme mash-up and backs it up with high-quality graphics and interesting game mechanics. I did think that the sound mixing was off and could have been improved, but the backing music itself was done to a really high standard. The game could have gone for a more dynamic alternative background when free spins are active, but that is just a personal preference. The same goes for medium volatility based gameplay, as some bettors won’t like this style, but other players will. Ultimately, I think that Sharkluck Holmes is a wonderfully whimsical game that has become one of my recent favourites. And with that, the game is a fin!
