The joker has always been the most controversial symbol in any game, whether that be an innocent game of card or a thrilling slot machine. It is the wild card, the unexpected factor in any narrative. We have seen this menacing feature pop up in many other games before. Take Joker Pro for example, one of the most renowned slot machines out there. Yet, when we thought such a masterpiece could not be topped, we are here to present a smashing slot by renowned software provider Play’n Go.

This review is going to be about Mystery Joker and it will leave you coming back for more time and time again. This wild ride of a game is going to make the hair on the back of your neck stand on end. You will never know what is going to happen with this game, whether you will leave empty handed or win some massive prizes.

Game Mechanics of Mystery Joker

A classic and timeless slot design, that is what Mystery Joker is all about. It is a very simple layout, nostalgic when you think about it: 3 reels in 3 horizontal rows. A throwback to the old school slot machine cabinets you would find in your local pub. True to its simple nature, there are only 5 paylines to be observed on Mystery Joker. Coin sizes can of course be adjusted at any point in time in between spins. Coin sizes come in the following values, making it easy for the player to tailor their wager to their preferences: 0.50, 1.00, 1.50, 2.00, 3.00, 5.00, 10.00, 25.00, 50.00 and 100.00. You won’t find any distracting or confusing gameplay features here. Mystery Joker is for players who just want to win a little bit of extra cash. Okay, perhaps a bit more than a little extra cash. Mystery Joker has a maximum jackpot available for those extra lucky players of 10,000 credits in their local currency. All in all, due to the low amount of paylines and high wagering options, Mystery Joker can be classified as a highly volatile slot machine. This makes the game perfect for players who are after big cash, high rolling players if you will, rather than players who are there for the entertainment. Players who are more into playing for fun rather than winning big can try out slot machines with a lower volatility. We would recommend the following games: Finn and the Swirly Spin and Jumanji by NetEnt and Tut’s Twister by Yggdrasil Gaming. 

Slot Features on Mystery Joker

On Mystery Joker, you will not find intricate and confusing features as you would on the modern video slots these days. Nowadays, all slot machines are filled to the brim with different kinds of wild symbols, flashy animations and other shenanigans to keep in check. For players of the older generation, who enjoy a more simple and straightforward style of playing, this slot machine is perfect. All the player needs to do is hit the spin button on the right side of the screen to start spinning the reels. This can be done after the player has chosen their desired coin size. Should you wish to multitask or have very little time to pay attention to the screen, you can opt for an auto-spin. The auto spin feature can be found below the normal spin button and players can select their desired amount. After the desired amount of automatic spins is selected, the reels will start spinning on their own accord. This leaves you with the time and freedom to step away from the screen and come back later to check on your winnings. Real handy-dandy, if we must say!

The symbols you will find on the pay table are of course modelled after the classic pub slot symbols like cherries, lemons, bells and all that jazz. Of course, there is also a joker symbol which is needed to progress to the Free Spins bonus round. 

Free Spins Bonus Round and Scatters
Scatter symbols are the only special symbol you will find on Mystery Joker. This symbol is of course modelled after a joker’s hat, tying the whole theme neatly together. By landing 3 of these symbols onto a connecting payline, the player will be able to trigger the Free Spins bonus round. The bonus round is quintessential for keeping a fast and dynamic feel to the game. Once the player has landed 3 of the Scatter symbols, they will be awarded with 10 Free Spins. These free spins will be played with the initial bet used to trigger the bonus round in the first place. The Free Spins bonus round will end once all Free Spins are exhausted. Contrary to some other video slots that implement the scatter-free spins dynamic, there is no option to accumulate extra Free Spins during this round. 

Mystery Wins
What makes this game so extremely volatile and thrilling to play, is the Mystery Wins feature. This feature can be triggered at random during the Free Spins round and awards the player with a random multiplier on their winnings. Multipliers can range from 1x to 100x your bet, resulting in some massive wins out of the blue!

A Final Word on Mystery Joker

Simplicity at its finest, that is what Play’n Go was going for when they decided to create the Mystery Joker slot machine. And what a good job they did. The game is easy to play and pays out nicely when it comes to winnings. The gameplay is dynamic and thrilling, allowing for a fast pace of play style. Players who identify as real high rollers are sure to enjoy this game due to its refined straight-forward nature.
