Unfortunately after a long time spinning this slot, I realize that hitting average does not seem to promise anything. The wild symbol is not displayed by rolling on the reels, it eventually a firefly lights randomly some high symbols to turn them into wilds. The truth is that I've been under the impression that these wilds are not designated at random but selectively, this is not a statement but a matter of my personal perception, but it seems that wilds are deposited mostly on the precise places where they are most useless, and whatever the case, this situation has created an uneasiness in the way I contemplate this game.
On the other hand, I found that the activation of the round of free spins is a pretty rare event despite it is achieved with the occurrence of only two scatters with the image of the fire, one on reel 1 and the other on reel 5, and 7 free spins also seem to be few for a low hit average slot like this one; during the free round fireflies do not turn independent symbols into wilds but entire reels, improving thus a little the performance of this game, but I do not know if this is enough. Amaya has many good slots in its portfolio, and frankly I do not think I lean toward "Fire Flies" when I want to play in a casino that uses this software provider.
