How to Play

If you are not yet familiar with online slots but want to play Mystery Joker, here is a simple explanation of how to do it.

  1. Wait for the game to fully load
  2. Click on the continue button to enter the slot
  3. On the bottom bar, choose one of the betting values available
  4. Click “Spin” or, if you prefer, select “Auto play” to play more spins automatically

Mystery Joker is a slot with a very classic layout, containing only 3 reels and 5 pay lines. Unlike other titles, this slot does not have coins, so just select the bet amount to start. The minimum is €0.50 and the maximum is €100, which appeals to everyone from beginners to Highroller bettors.

Mystery Joker RTP and Volatility

9 
Enjoy this funny mystery with a 96.98% RTP rate and medium volatility.

Despite having medium volatility, many players may find it difficult to find winnings on Mystery Joker due to the fact that the slot only has 3 reels and not 5, like the most popular titles today. Anyway, if these victories come, the values vary between highs and lows. The RTP of 96.98% is a little above average, being really good.

Wins come when you manage to complete one of the 5 pay lines, showing the same symbol on all reels. In addition to the normal symbols, this slot also has a Scatter.

Theme

7.3 

The first thing you notice when you enter the Mystery Joker slot is the classic theme and its simple layout. From the number of reels to the symbols used, the slot screams retro, which always pleases many players.

Overall, the slot doesn't have many elements in its design, preferring to keep a more clean look. The sound is also reminiscent of the classic, starting only when the reels start to spin and disappearing as soon as they stop.

As usual with more classic slots, Mystery Joker offers a total of 5 normal symbols. Among them, we see very common elements of old slots, such as fruits, bells, and glowing stars. The star is the one that offers the highest payout of these normal symbols.

In addition to those mentioned above, the slot also has a Scatter symbol represented by the colorful jester hat. That's the one you want to find, as 3 hats trigger free spins and the chance to receive a mystery win.

Great slot! I love it! Especially when you get the bonus round and when it decides to "go in your favour". Rizk casino offers it as one of the games you can use your won free spins for, and this is most of the time my first choice. Interesting with a combination of traditional and modern slot machines.
