Mystery Joker slot

Mystery jocker slot
Creating the Mystery Joker slot, developers PlayN Go did not set a goal to get a super design and dynamic plot for themselves. Instead, the task with which they coped brilliantly, was more ambitious; to adopt the classic model of the first gaming machine created by American Charles Fey in the late nineteenth century to the present day requirements.

To understand the difficulty of this enterprise, you can imagine what efforts are needed to convert the vintage cars in the machine, to the exterior and power of most modern machines. Of course, only top-class professionals can perform such tasks.

Personal testers opinion

The rating of the slot machine for the wagering is 5.83 out of 10, which allows us to recommend it to the bonus hunters. The free spins are found in every 60th spin (statistically, 1,67%). But you will have to wait for the pay combinations in the main game because out of 100 spins only 12 spins will be successful. My maximum winning during the usual spins was 126x my bet, and for the bonus feature was 21x.

Description of the slot machine

In the Mystery Joker slot, players meet the classic structure of all existing slots. Game symbols are fruit sets as some are cherries, lemons and grapes currant which also reminds us of the plot of the first slot machines. By changing the appearance of the playing field, adding a base image and the general background of colourful shades and colours, the developers have created an attractive, beautiful, bright, and eye-pleasing picture.
