Mystery Joker Slot

Welcome to the delightfully fruity world of Mystery Joker classic slot. In this retro slot Play’n GO have stripped away most of the bells and whistle, recreating a classic fruit slot but with some cool new features!

Theme, Sounds and Symbols

Mystery Joker pays homage to the classic fruit slots with a simple layout, basic design, gaudy colours and engaging gameplay.

The game environment is a single colour background, with a gradient, dotted with question marks. Had it been green instead of purple (in the base game) or red (during Free Spins) we would have thought this Play’n GO slot game was paying homage to the classic Batman villain, The Riddler!

The actual reels are strongly defined by thick gold piping, and the five fixed paylines are made crystal clear through five giant gold coins running down both sides of the reels numbering 1 through 5 in accordance with the reel they’re pointing to.

Only six symbols populate the reels themselves. Most importantly there is the Joker Hat which acts as the Scatter and will trigger not only Free Spins but also the Mystery Win prize. The remaining five symbols are fruit slot classic; Stars, Bells, Blue Berries, Lemons and finally Cherries.

The music and sound effects that accompany each spin are modern versions of the midi-tunes used in the early days of slot machines. While still completely random and even inane at times they are clean sounds which don’t jar your eardrums as repeat over and over.

Game Mechanics

Mystery Joker is definitely a casino game you where you want to make use of the AutoPlay feature. With a simple 3x3 grid the spins come thick and fast and Play’n GO have even gone to the trouble to display both on the reels and on the upper marquee your win value and on which line the win took place. A novel fixture in a world of 1000+ ways to win where most of the time you’re trusting the game engine about whether a spin won or lost.

Even with this simple interface Mystery Joker offers you the chance to play as hard or as soft as you like in pursuit of the Mystery Win bonus. Simply select your preferred bet size on the slider below the reels. Bets range between €0.50- €100.00 per spin!

With an RTP of 96.98%, this tidy little fruit machine is no slouch in the jackpot department! Spin to win on Mystery Joker and you could win up to 30,100 coins!

Bonus Features

Mystery Joker is a slot machine with only 2 Bonus Features both which revolve around triggering Free Spins!

Free Spins & Retriggers

Triggering Free Spins in Mystery Joker is the same as in most online slots. Land 3 or more Scatters on the reels, and you will be rewarded with 10 Free Spins! It is also possible to retrigger up to 50 additional free spins in this game mode!

Mystery Win

This is where the big cash prizes are hiding when you play Mystery Joker! During Free Spins mode landing 2 or more Scatter symbols on the reels will reward you with a Mystery Win. This Mystery Win will be a randomly selected multiplier of your bet ranging from 1x to 100x! Playing max bet of €100.00 per spin and landing 100x multiplier on top of your existing wins would be a rather sweet cherry on top!

Play ‘On The Go’

It is no mystery that Play’n GO are dedicated to your slots entertainment. They have ensured that Mystery Joker is available on all mobile devices across all platforms including Apple iOS, Android and Windows!

CasinoWow Game Verdict

Mystery Joker is a fantastic homage to the classic fruit slots of the past. The graphics are crisp, the sound profile is clean, and the simple gameplay is a welcome change from the sensory overload of some of the mega slots. If you need a break from the madness and are craving a little 3x3 fruit slot therapy, we highly recommend you give Mystery Joker a spin!
