An interesting detail on the theme of this slot is that, as the troll that appears on it definitely does not look like the one in Shrek film, it becomes clear that the game has been based on the book “Shrek!” written by William Steig, since all we know that the other characters such as Puss in Boots, Pinocchio, Donkey, the Gingerbread Man and Lord Farquaad only appear together in this fairy tale specifically.
As for the game system, “Troll's Tale” is one of those slots that have more special symbols than desirable, and by this I mean not to the wild symbol in any time, I mean to the Bonus, Spins and Sticky symbols which are the directly responsible for triggering the bonus round, free spins, and sticky wilds features respectively, which incidentally are activated at a rather slow pace and in my opinion have a potential to generate gains very limited, except perhaps for the bonus round where normally it appears available an award of 100x the total bet to be won if we manage to guess which one is the right choice.
The main reason why I do not really like the constant appearance of so many scatters it is because they usually diminish our chances to hit normal lines as these symbols constantly interfere in their formation; sometimes it is so exaggerated the number of scatters appearing on the reel, one time I even got 4 different scatters only on row 2 plus others more scattered on the other two rows, and sadder still, that was not enough to activate any feature. Personally, I think if Nektan had intended to make more enjoyable this game through the addition of special features they could have chosen other systems less invasive to unleash them since at times you even start to doubt about this slot has a theoretical RTP (return to player) of 95.01%.
In short, the game is attractive both for its appearance and collection of special features, but in practice you can easily come up with a poor performance during the base game and long droughts of bonus rounds and other features that, if you are one of those players able to keep a cool head, you'll realize that the smartest thing you can do is stop playing, have a cup of coffee and then start looking for a new game.
