Bets can be placed from 0.50 to a maximum of 100.00 – high rollers will love the return potential with big bets. Jester Joker is the key to the free spins and instant wins and you could certainly be laughing all the way to the bank with the 100x your stake winning amounts on offer. The joker is often thought to be a wild card – something that doesn’t offer much, but in this slot game, he’s the star of the show.

Jolly Jester

The Mystery Joker logo will flash to the top of the slot machine every time you press spin. A message bar is sitting beneath the logo with little messages of encouragement whilst you play. Winning paylines are highlighted on the message panel and on the reels when you hit a winning combination.

Gold encases the three reels with the five paylines piercing through each reel. All five paylines need to be in play with every spin, but the good news is you can adjust your bet to suit your budget.

Use the control panel to set your bet with the pre-set bet buttons. Paytable, autoplay and spin are also present along with your balance, bet and total win.

Symbols found upon the reels are; grapes, lemons, cherries, golden bells, jester’s hat and golden stars. There may well be only a handful of symbols, but that has no effect on the amount you can win and the frequency of hitting a win.

Lovely Money

The biggest wins come from the mystery win feature – this is only active when you have triggered the free spins. A mystery instant win of up to 100x your total bet can be awarded. All other symbols on the reels offer between 10 and 50 coins for three or a kind.

Basic but Brilliant Bonuses

Spin those reels and land three jester hats on your paylines to trigger the free spins bonus. You will be awarded a number of free spins up to 50 in total and these will play out automatically, so you don’t have to press a thing.

Mystery wins are active when free spins are in play. Any 2 jester hats in view will trigger a mystery win where your screen will turn purple and your mystery amount will be shown. There’s no end to the amount of mystery wins you can trigger during free spins.

Mystery Machine!

Boy, we are totally impressed with the Mystery Joker slot game from Play ‘n Go – it’s absolutely amazing.

With Mystery Joker being a medium variance retro slot machine, you will need to match three of a kind in order to win – but base game wins come round quite often, so you shouldn’t be playing too long before hitting a win or two. Sounds and graphics are great and drag you into the game and the way that the slot game has been designed allows for effortless gameplay with no distractions.

If the musical interlude gets a bit much, you can switch this off via the control panel.
