About Book of Oil
Book of Oil is a thematic slot by Endorphina in a 5×3 format with 10 fixed paylines, inspired by the atmosphere of oil fields and industrial азарт. The game feels focused and structured: spins proceed at a moderate pace, and key moments are connected with the appearance of the Book symbol. The overall style is rendered in warm golden-fiery tones, creating a sense of hidden wealth beneath the surface.
The game field is built on the classic 5×3 layout with fixed paylines. Wins are formed from left to right when matching symbols land on active lines. The mechanics remain clear and traditional, making the process predictable and suitable for a measured style of play.
The main symbol is the Book, which performs a double function and can act as both Wild and Scatter. It becomes the center of the entire dynamic: its appearances create the main intrigue in the base game. The potential increases in the bonus mode, where a special expanding symbol can occupy the entire reel and significantly increase total payouts.
The Wild replaces standard symbols, helping to form combinations, while the Scatter activates free spins. During free spins, a special symbol is selected with the ability to expand across the entire reel. A risk game to double the win after a successful spin is also available.
The RTP is around 96%, and the volatility is high. Book of Oil is suitable for players who prefer less frequent but more substantial wins and rely on the bonus round with expanding symbols.
