Within the bonus pop buy feature, players can play free spins with the expanding symbols feature at any time.
During the game, the book symbol acts as a scatter and wild. Players can also get hypnotised by the Oil Tycoon symbol which results in the Oil Derricks and Tanks dancing on the reels.
Moreover, during Book of Oil’s bade game, when three scatters land on the reels, they trigger 10 free spins with expanding symbols. At the beginning of the feature, a special symbol is randomly selected, the wild symbol is not included.
Special symbols expand after the payout of regular symbols. The expanding symbol pays for combinations of a kind in adjacent and non-adjacent positions, and only on enabled paylines.
