One aspect of this slot that confuses me a bit, it is its incredible similarity to the format of slots manufactured by the German company Bally Wulff, similarity that can be seen in the quality of graphics, type of icons, number of lines and mainly in the type of special feature implemented in this game, which is a round of 12 free spins + “special expanding symbol.” In the information section of the game, and more precisely in “feature” explaining, it says the round contains 10 free spins, but this must be the product of a small oversight since, in reality, they are 12.
This feature is that before starting the round of free games, one regular symbol is chosen randomly in one of the pages of a book to make it a special symbol during our spins; first, this symbol expands through the entire reel and then it forms lines with the other matching symbols regardless of whether these reels are located in adjacent positions or not.
Indeed, my first experience with this slot was really exceptional thanks to this special feature, because after almost 70 unproductive spins, finally could trigger my first round of free spins; my special symbol was “10”, but the most exceptional thing it was that during my free spins, book symbols began to appear more often than during the base game and thus I could manage to re-trigger this round in 6 times for a total of 84 free games.
At the moment of activating this round, my total bet was just $0.20, and during the 84 spins, my total earnings were $85, which is a win of 425x my total bet; a no negligible sum in my opinion.
However, I do not know how normal it can become the fact of re-trigger this round of free games so many times in this slot, what it’s almost certain, it is that this slot depends very much on this feature to be an interesting game and, if at any time, book symbols begin to dwindle, it is almost certain that our balance will start to collapse gradually as it has happened to me in similar - almost identical - slots manufactured by the company “Bally Wulff.”
Either way, I think it must be given the benefit of the doubt to this slot; try it out and just hope for the best, that is, expect that its behavior somewhat resembles the great experience previously narrated by me.
