Book of Oil Online Slot Features  

This game is pretty rich in bonus features, and these include Wilds, Scatters, Bonus Pop Up, Free Spins, and a Risk Game. More about each feature further in this Book of Oil online slot review. 

Talking about customizable features for the game, pay attention to the Autoplay mode, and Turbo mode. The Autoplay is convenient when the player wants the game to spin many times without the need to click the button for each spin. Advanced settings for the Autoplay allow the player to make sure the Autoplay stops when a certain condition is reached. 

Turbo mode, in its turn, spins the reels faster, and thus makes the game more dynamic, and more exciting. Turbo mode is perfect for players who are more interested in the bet outcomes than in the process of playing and watching the reels spin. Neither Autoplay nor Turbo mode can impact the bet outcomes. 

Wilds + Scatters 

It seems that the symbol of the book works as Wild and Scatter at the same time. As a Wild, it completes the paylines. As a Scatter, you must get three or more symbols on the grid to activate the Free Spins. 

Bonus Pop Up 

This is basically a Bonus Buy feature. When this feature pops up, the player can choose a bonus they want to get, for a certain payment in the game. 

Free Spins + Expanding Symbol 

When Free Spins are triggered, the player gets 10 games, but before the games start, a random symbol is chosen by the game to become an expanding symbol. The Book Wild cannot substitute that symbol during the Free Spins. The expanding symbols complete the paylines. During the Free Spins session, Free Spins can be retriggered again. 

Risk Game 

Book of Oil has a classic Risk Game, when the player needs to choose a card, and win from the Dealer by choosing a card of a higher value. If the player wins, their winnings are increased; if the Dealer wins, the Risk Game ends with no winnings for the player. 

Book of Oil RTP Percentage 

The Book of Oil RTP rate is 96%, a nice rate for long term real money gamble.
