Book of Oil (Endorphina): Slot Review & Theme:



To say that the oil industry is booming would be an understatement. It’s one of the top ten highest-grossing industries in the world. In recent years, the oil industry has amassed a value of up to $5 trillion. The gameplay of this slot title perfectly represents the perpetual ladder business people must climb to become successful in the industry.

The background of this video slot features a desolate landscape where vast amounts of oil are pumped from deep underground. The oil drums tell a story of the endless cycle that the oil rigs complete. In the distance, giant skyscrapers tower over the desolate land, signaling that this community more than profits from the income generated by the oil rigs. Clearly, this community basks in great wealth and will likely continue to expand its reach.

Features of Book of Oil



A handful of unique features elevate the gameplay in Book of Oil at BC.GAME. These features may be seen in many other slot titles, but they help complement the gameplay and create an added gamification layer.

Special Book Symbol

Like many other titles within the Endorphina Book of slots saga, one particular symbol is the cause of most of the key features within this slot. A dual wild and scatter symbol is styled as a book and looks like a safe. During the base game, this symbol will substitute for all regular pay symbols, and it will also launch players into the bonus round with ten free spins once three of these symbols land.

Book of Oil Spins

Once players land three or more Book of Oil symbols, the bonus round will begin with ten free spins. After the bonus round has been activated, the slot will select a random symbol with the opportunity to expand. The chosen symbol will only expand once enough of the same symbols are in view to form a winning combination. The symbols will then expand to cover their respective reels and increase the winning combination's value. Special symbols will expand after the payout of regular symbols. It’s also important to note that the wild symbol will not substitute for the special symbol selected to expand.

Gamble Feature

Endorphina has become known for its captivating gambling round. This gamble feature is also present within Book of Oil at BC.GAME. After players have achieved a winning combination, the value of the win that has been triggered can be gambled. Once the gamble feature has been selected, the feature will display the dealer’s card. The game will then show players four cards with a hidden value. Players must choose any of the four cards, and if the selected card’s revealed value is higher than the dealer’s card, the gamble feature will double the initial winning amount. Players can do this up to 10 times consecutively, and the gamble feature will double each win. If players happen to select a card with a value that is lower than the dealer’s card, the initial winning amount will be voided.

Feature Buy-in

The feature buy-in option within Book of Oil at BC.GAME can launch players directly into the gameplay of this title. The cost of the feature buy-in option corresponds to the total bet amount and the option feature buy-in option that has been selected. Players can enter Book of Oil spins with ten free spins and a randomly selected expanding symbol, or they can enter the Book of Oil spins with ten free spins and choose a symbol they wish to expand. The option to have a randomly selected expanding symbol will be far cheaper than the latter option. It’s also important to note that the availability of the feature buy-in option will depend on the jurisdiction to which players are subject.
