Surrounded by all the golden beacons, this mighty treasure shines so bright, that the stars become dim. The Book symbol acts as Scatter and Wild, revealing the craziest wins of all time. Players also get hypnotised by the Oil Tycoon symbol and the stunningly bright symbols of Oil Derricks and Tanks which promptly dance on the reels. All together, they create an incredible upper-class feel within the Book of Oil game. When three Scatters land on the reels, they trigger 10 Free games with an expanding symbol. At the beginning of the feature, a special symbol is randomly selected. During the Free games, the Wild cannot substitute for the special symbol.
