Are you a fan of murder mystery detective shows on TV? Or perhaps a classic whodunnit novel is your thing? Well, inspect a bit closer as our investigation continues with Coffee House Mystery, by Merkur Gaming.


This is a fantastic 20 fixed line and 5 reel slot with some unique wild action, a big wild and an amazing multi-layered free spin bonus feature. All of this action is set against the backdrop of a classic murder mystery, as you look for clues to find the culprit!

Murder mysteries, or detective tales, is one of the most widely enjoyed literature or visual media genres. This genre came from authors in the mid nineteenth century and rapidly developed through the twentieth century. With interesting characters, both on the good side and the bad, it is no surprise that this genre is so popular. It gives the audience the chance to enjoy a story, but also to put their own detective skills to the test as they look for clues to work out who committed the crime!

The story in this game goes that a customer of a fancy coffee shop many years ago has met their maker in suspicious circumstances. It’s time to get your magnifying glass and inspect the crime scene to get closer to the culprit! There are some characters that you will need to assess and interview, including Dan the private detective, looking very much like our favourite detective from Baker Street, Sherlock Holmes. You will also have to work out if the murder was anything to do with Miss Lucy, the only witness at the scene. Was it an extra ingredient in the coffee that caused the death? You will also need to consider the motive of the undercover cop, John, in case he is not to be trusted!

On top of the fantastic storyline, amazing visual and audio experience, the gameplay is totally immersive in Coffee House Mystery. It is also completely free to play on mobile and tablet or even on desktop.

Coffee House Mystery's premium symbols

You will enjoy the variation of the symbols in this slot, and the premium symbols are all things you will find in a coffee shop or in a murder mystery scene in the 1940s. The pocket watch is the highest payer with 5 symbols on a payline offering 10x your stake. The teapot is next, at up to 6x your stake, and then there is a tasty looking cake paying up to 4x and a napkin paying up to 2x your stake. It will put you in the mood for a spot of coffee and cake, but there’s no time for refreshments, it’s time to spin and win.

Coffee House Mystery lower value symbols

As well as the classic coffee shop and murder mystery symbols that are higher payers, you will also be able to find a win with some lower value, yet still worthy, symbols to hit. These are the A, K, Q and J. The A and K offer up to 1x your stake and the Q and J offer 0.6x. As you can win on multiple paylines, these lower value symbols can really add to your tally, so don't miss out.

Scatters and free games in Coffee House Mystery

Diamonds are a girl's best friend as the song goes, and they could be your best friend on a spin, when you find 3 of the scatter symbols on your screen. You will see the symbol is a huge, sparkling diamond in a case with a spotlight on it, showing the glitz and jewels often seen in murder mystery slot stories of this era.

Landing three of these will initiate the Triple Clue free games feature round, with 10 free spins to get you started. You will need to land the scatters on reels 1, 3 and 5. Your free games will start with a normal play window similar to the main screen. What is unique about this feature is the chance to open up two more simultaneous windows to triple your chance of a big win! If you re-trigger the free spins by landing 3 more scatter symbols on reels 1, 3 and 5, then great news: you have unlocked another window for the remainder of the free spins AND you have been awarded 10 more free games. The fun doesn't stop there however, as if you land another 3 scatters on reels 1, 3 and 5, then you will unlock ANOTHER window that will remain open for the remainder of the free spins AND get another 10 free games to play! That is a potential 30 free games across 3 windows, offering the chance of winning some spectacular winners.

The 4 wilds of Coffee House Mystery

This game just continues to offer some amazing features and gameplay to keep players coming back again and again. The wilds on offer are truly unique, with some fantastic chances of winning big. Let's take a look at the 4 wild symbols and their specific roles in this plot.

Detective Dan wild on Coffee House Mystery slot

You might wonder whether Detective Dan, the private detective, is actually helping you solve the Coffee House Mystery, or if he is somehow involved in more suspicious activity. Either way, the symbol is an expanding wild that will cover four symbol positions. It can land on the four corners of the pay windows and will land totally randomly. Detective Dan resembles a classic early 20th century detective.

Officer John Wild on Coffee House Mystery slot

Are you going to trust this so-called elite undercover cop, Officer John? He could be a great asset to the investigation, or he could be trying to con you to get away with the perfect crime! Officer John Wild is an expanding wild on a vertical reel that can randomly appear on the 3rd or middle line of the window. It will cover three positions and offers that prime time central point that can link your payline together. Officer John is a distinguished looking character, well presented and standing assured as he expands across your reel.

Miss Lucy Wild on Coffee House Mystery slot

The need to carefully look after your witnesses is acknowledged by all good detectives, and Miss Lucy is a key witness. But does she have some skeletons in the closet that mean her past is going to catch up with her? Miss Lucy Wild is also an expanding wild symbol, which will go in both directions - both vertically and horizontally - and it covers a whopping five positions. You could say that the shape of the expanding wild is like a plus sign, or the cross in the middle of a Swiss flag. It can be positioned on the first three reels or the last three reels. She has a traditional Charleston style look and holds out a sign saying Coffee House. You will be keen to speak to her as part of your investigation!

Espresso Wild on Coffee House Mystery slot

Time to wake up and smell the coffee to solve this case. The classic espresso is a mainstay of coffee shops, and you will see this special blend of espresso pop up that could be a top clue to solve the Coffee House Mystery. This is also an expanding wild that could randomly appear in the centre of the reels and will totally cover the reels 2, 3 and 4. The coffee looks steaming hot, with a chic red coloured cup and saucer. Delicious!

All games by Merkur Gaming offer an extra feature by giving you the chance to gamble your win. This is like a classic card game of choosing the colour of the next card - red for diamonds and hearts, or black for clubs and spades. Pick the right colour and double your winnings. Pick the wrong colour and you've lost the lot! You can cash your winnings out at any time when clicking the symbol that looks like a money bag. To keep the action coming, you can also aim for a big win by winning multiple guesses and take home the amount at the top of the screen. You should be aware that this feature is disabled during autoplay, so if you want to take advantage of this cheeky bonus, then switch off autoplay before you start. You can always Play Merkur Slots in Demo Mode before you decide to play for real money. You can Play Demo Slots for free here at Slots Temple for as long as you like.

Coffee House Mystery graphics

The imagery is fantastic in this game and Merkur Gaming has really delivered a perfectly pitched set of graphics to set the scene. The characters are intriguing and well put together and the other symbols all fit in well. The colour coded paylines all give you a chance to follow the right path to glory and the background makes you feel like you're in the coffee house enjoying one of those special blend espressos! The logo for Coffee House Mystery looks like it could be on the cover of a murder mystery novel, so everything has been carefully themed.

The 25 spin review test of Coffee House Mystery

We always like to play the games we review to give you a chance to understand the features in detail. We started off with stakes of £1.00 and set the autoplay to 25 spins. In this test, we quickly hit a Detective Dan expanding wild that brought in £12.00, which was a great start. We then hit a few losing spins, but still enjoyed the action, sounds and graphics. Then we landed 3 scatters on the right reels and really enjoyed the interesting multi-layered feature. We played 9 of the 10 free spins, but on the last one managed to hit another 3 scatters which re-triggered the round and opened up a new pay window! On the next 10 free spins, we didn't manage to open the third window, but still ended up with £15.50 from the 20 free spins. Maybe next time we will unlock the third pay window and see some even bigger wins!
