The so-called mystery symbol is always very popular among players. This valuable symbol has the ability to substitute for any other symbol in the game to directly bring in a handsome win. This means that one symbol will be converted into another so that the Player will get a higher win on the bottom line.
Basically, the mystery symbol can appear in both the base game and the bonus game. As a rule, the mystery symbols are triggered randomly.
A popular slot with the mystery symbols is the Mystery Reels slot, which was developed by Red Tiger Gaming in 2017. Instead of a wild symbol, the mystery symbol is used in the case of Mystery Reels. When the mystery symbol appears, a number is displayed at the same time. This number indicates how many other symbols on the reels are taken by the mystery symbol. The special thing about it is that the mystery symbol can even take the form of a bonus symbol and in this way trigger the promising bonus round. Besides the mystery symbol, the Mystery Reels slot also features the Wheel Bonus.
