Mystery Joker RTP and Wagering

Mystery Joker uses 3 reels, 3 rows, and 5 fixed paylines. Bets range from £0.50 to £100.00.

The aim is to spin the reels and match three standard symbols on a payline to win a cash prize. You can trigger the Free Spins feature if you land enough Scatter symbols, too.

Mystery Joker is a medium volatility slot game, and it has a fantastic Return to Player (RTP) of 96.98%. That’s much higher than the 96% average for slots. Theoretically, the game can return almost £0.97 for each £1.00 wagered on average, though that’s not guaranteed. RTP calculations are based on thousands of spins played across long periods, so they aren’t an exact representation of how much you can expect to get back.

The biggest payout available in Mystery Joker is 6,020x your bet. But considering how low most of the payouts are, reaching that top prize seems virtually impossible.

Mystery Joker Symbols and Audio & Video Design

As Mystery Joker is based on classic fruit machines, it’s designed to have a simple aesthetic. This gives the game real retro charm, and it should satisfy fans of traditional slots packed with fruity symbols.

The base game features a plain blue background, but during the Free Spins feature, this changes to a red backdrop covered with question marks. The illuminated logo above the reels lights up and flickers while you play, which adds to the illusion that you’re playing a real fruit machine. The ‘total win’, ‘bet’, and ‘balance’ dot matrix displays below the reels are another realistic touch, too.

Music plays when you spin the reels, accompanied by a ‘whooshing’ sound as they whizz by. But an upbeat little tune triggers whenever you win, too.

Mystery Joker has just five standard symbols: cherries, lemons, grapes, bells, and stars. Each pay out for three on a payline only. The star is the most valuable: get 3 to win 50x your stake.

The jester’s cap is the Scatter, and might appear on any spin. This triggers the Free Spins feature and awards a mystery win. No Wild symbol appears in Mystery Joker.

Cherries

3 — 10x bet

Lemon

Mystery Joker Mobile Features

Mystery Joker was developed in HTML5, so you can play it on a mobile or desktop. You can expect to see the same vibrant graphics as on a desktop, with chunky symbols and plenty of colour. The simple controls and design make it a breeze to use on a smartphone or tablet, too.

Mystery Joker Bonus Features

Mystery Joker has two bonus features: a Free Spins round and a Mystery Win. Both revolve around the Scatter symbol.

Free Spins

Get three Scatters on the reels to win 10 free spins. You can retrigger the feature and get up to 50 free spins in total.

Mystery Win

When the Free Spins feature is triggered, two or more Scatter symbols will award a Mystery Win of 1x to 100x your bet.

Mystery Joker Final Thoughts

There’s not a huge amount to Mystery Joker, and that’s the point: it’s designed to recreate the experience of playing a fruit machine in a casino or bar. The visuals are bold, bright, and capture the look of a traditional slot machine brilliantly. The gameplay is fast and simple enough for all players to pick up right away, too.

One of the main highlights of Mystery Joker is the high theoretical RTP — 96.98%. That’s well above the industry average of 96%, and creates the potential for a good return (though it can vary from play to play). This helps Mystery Joker stand out from other classic-themed slots.

You can also trigger a Free Spins feature and land Mystery Wins of up to 100x your bet. The max win available is 6,020x your stake, though that seems highly unlikely when the standard payouts are so small.

Overall, Mystery Joker’s RTP and bonuses make it worth playing for fans of classic slots.
