The slot machine Secret of the Stones is a game produced by NetEnt presenting 25 bet lines as well as different types of Wild and Scatter symbols. It is a game inspired by Stonehenge, a Neolithic site that consists of stones which in antiquity was visited by pilgrims from all over Europe. All symbols in fact seem to be designed on the rocks, while the famous stones of Stonehenge can be glimpsed between the 5 reels. The symbol depicting a druid is the Wild of the slot Secret of the Stones. This symbol acts as a substitute for all other symbols to achieve the best possible combination, except for the Scatter. The latter, in a number equal to or greater than 3, activates the Free Spins mode, composed of 10 free spins. Before this begins however, the player will come across 20 stones and may choose one for every Scatter on the screen from the spin. The stones will hide bonus features that will be applied to the Free Spins mode, such as extra free spins (up to 10), win multipliers (X1 or X2), or 3 different types of Wilds that can be deer, owls and druids and will occupy the entire roller making it completely Wild.
