Book Of Oil operates on a 5x3 grid with 10 fixed paylines. Wins form by landing matching symbols on these lines from left to right. The Book symbol is key, acting as both a Wild and a Scatter. As a Wild, it substitutes for all symbols to help form winning combinations. The Scatter role of the Book is crucial for triggering the game's main feature: Free Spins with Expanding Symbols. Keep an eye out for the Oil Tycoon symbol, which is among the highest paying in the game. The game’s high volatility means you might experience longer dry spells, but the potential for big wins is there when the features hit.
The Book symbol doubles as a Wild, substituting for all other symbols to complete winning lines. However, during Free Spins, it doesn't substitute for expanding symbols, adding a layer of strategy.
After any win, you can choose to gamble your winnings in the Risk Game. This feature lets you double your win by picking a card higher than the dealer's. It's a gamble that can quickly boost your bankroll or wipe out your win.
The Bonus Pop feature allows you to buy direct access to the Free Spins round. It's a shortcut to the game's main feature, but comes at a cost.
Triggered by landing 3 or more Book symbols, this feature awards 10 Free Spins. During these spins, one symbol is randomly chosen to expand, covering entire reels and potentially leading to massive wins.
The Book acts as a Scatter, triggering Free Spins when 3 or more land. Landing 5 Scatters awards a hefty 200x your base bet, making it a symbol to watch.
With a 96.05% RTP, Book Of Oil sits just above the industry average, offering a fair return to players over time.

The game's structure suggests that players should be prepared for significant bankroll swings, making it ideal for those who enjoy the thrill of high-risk, high-reward gaming.
The betting range in Book Of Oil spans from €0.1 to €45, accommodating both casual players and high rollers.
