Mystery Joker Slot Review

Mystery Joker is a classic online slot from Play’n GO, with the joker serving as a scatter giving free spins and as a wild paying up to 100x bet. The feeling of this 3-reel, 5-payline slot is retro, with the symbols drawn from the days of the mechanical fruit machine. But the little extras add some excitement and volatility to what otherwise appears to be an old-fashioned and traditional game.

How to Play

Before you begin playing Mystery Joker, set your bet amount, from £0.50 to £100. Unlike many modern slots, you can only play a single coin, and there’s no max bet option, but that’s a pretty wide bet range. There is an Auto Play button on the bottom left. This will keep spinning for a set amount of spins up to 50, with some options to set different conditions for stopping AutoPlay. The 5 paylines — the three rows and the two diagonals — are always active, so you don’t need to fidget. Just spin away!

Important symbols in Mystery Joker

The most important symbol, by far, is the joker’s cap. If three appear anywhere on the reels, not just on a payline, a sequence of 10 free spins will be triggered, including the possibility of retriggering up to 50 free spins!  The combination of a joker’s cap with two of another symbol in a payline will trigger a mystery win of up to 100x your bet.  So the joker symbol effectively serves as both a scatter and a wild.

The other 5 symbols, from highest to lowest value, are:

  • Gold Stars
  • Gold Bells
  • Grapes
  • Lemons
  • Cherries


Mystery Joker has no progressive jackpot, and even the payline wins of 3 in a row will only pay at most 50x bet (stars) and at worst 10x (cherries), and even that is divided by the 5 paylines. However, the prospect of an up to hundredfold win during the free spins is a serious win — nothing to joke about, especially if you wagered £100! You can laugh all the way to the bank.

Special Features and Bonuses

As a classic slot, Mystery Joker is not rich on bonus features, though the free spins for getting 3 jokers and the ability to get a mystery win of up to 100x during free spins is a treat, and adds real drama to the spin sequence.

Graphics and Sounds

Mystery Joker is so retro that it stays silent when you’re not playing, and only starts making sounds when you spin. The spinning sounds are upbeat, and the win sound effects are even more cheerful. But this slot will not win any awards for best soundtrack. The graphics are clean but unexciting.


Mystery Joker is a classic slot, hearkening back to the first generation of games with classic fruit symbols and no big bonus features. Still, this slot does give a nod to scatters and wilds, and when free spins are triggered you can have some real excitement in anticipation of a big mystery win. With a Return to Player of 96.98%, this slot is calculated to deliver a chance of winning considerably more than the industry average. Give it a shot and maybe you will have the last laugh!
