Mystery Jack Slot Review

Hot Spot and 777 slots are trendy among online casino players, but Mystery Jack slot has remained underrated. It has been released by the Polish developer Wazdan, and in this guide, we will show what features and advantages the game has.

Mystery Jack game rules and features

Mystery Jack online consists of 3 reels and 3 rows. If you are still looking for interesting classic slots to play online, we can recommend the game created by Wazdan team. Amazing adventures and incredible wins await those who love to play slots with free spins in this fun Wild West-themed game about Jack the Tramp. The outcome of each round of the Mystery Jack game is based solely on a random number selected by the RNG (random number generator) feature. The sequence of random numbers generated by the RNG "tells" the reels when to stop, thereby affecting the outcome of the casino game. This means that the same game with the same random number must always produce the same result. Mystery Jack game has the following features:

RTP: 96,79%;
Volatility: medium;
Layout: 3-3;
Paylines: 27;
Minimum bet: $/€ 0.1;
Maximum Bet: $/€ 100;
Bonus: Gamble, Free Spins, Bonus Round, Wild, Scatter.

The reels of this slot are filled with icons such as strawberries, raspberries, plums, watermelons, oranges, grapes, lemons, cherries, an angry red bull, and the Mystery Jack icon. Matching three Mystery Jack symbols will give you about 16 credits.

Mystery Jack game bonus features

In Mystery Jack slot you will see a Wild Symbol, represented by the character Jack. Wild symbols substitute for all other symbols, except for the mystery symbol, to increase your jackpot chances. The Mystery Symbol is one of two Scatter symbols that the Mystery Jack slot machine boasts, meaning that they pay for landing anywhere on the reels, not necessarily on a win line. Landing 3 scattered Mystery symbols will result in prizes ranging from 1 to 500x coins. Mystery Jack slot for free online also has a Gamble feature, present in most Wazdan games. It allows you to double your winnings. If you decide to place a bet, you will be redirected to a simple card game where you can choose between red and black. You choose correctly, your stake is doubled, and you can move on to the next round. Again, completely optional, you can choose to collect winnings and return to the main game at any time.

Mystery Jack Slot Machine Interface

The Mystery Jack game will transport you to the American Wild West desert in the scorching sun, full of cacti and reeds. It will take you on an adventure like no other. Most of the symbols will not be new to you, as they can be found in many classic slot machines: fruits, sevens, bars and bells. More interesting for players will be symbols with stars, replicating the sheriff's badge, bulls, bandits (Jack), cabs and wagons.

Summary

The Wazdan company is known in the online gambling market primarily as a modern manufacturer of online slots software. Not surprisingly, all its slots are available not only to play from a computer. You just need to have an Internet-enabled phone at hand to dive into the world of amazing adventures with Jack the Tramp. HTML5 technology allows you to adapt the machine to different mobile devices. You can use your Android smartphone, iOS or Windows tablet. You don't need to download additional programs on your phone, you can safely play online from your mobile browser.
