Book of Oil is a casino game created by Endorphina, offering players a mix of simple access, real-money betting potential, and clearly defined game statistics. Before starting a session, players can check the key numbers behind the game, including its 96.05% RTP, very high volatility, and maximum win of up to 1000x. The RTP shows the theoretical long-term return of the game, while volatility helps explain how wins may be distributed during play. In the case of Book of Oil, the very high volatility suggests a more unpredictable experience with larger payout potential. The maximum win of 1000x gives the game its reward ceiling. This figure is especially useful for players comparing casino games by risk level, payout potential, and session style. If you enjoy games from Endorphina and want a title with a high-risk structure and large win potential, Book of Oil can be a strong pick to try.
