Book of Oil

How to Play

It’s possible to play, even when on the move, thanks to the mobile version. Thankfully, the reel machine is still compatible with desktop and tablet devices. Before risking your dough, consider gambling the Book of Oil demo version from our GoodLuckMate website. After entering the game’s interface, you’ll need to change it to your preferred language for compatible gaming. Click on the Menu icon, and under “Language,” choose the flag and suitable region.

You’ll notice that the reel set in the Book of Oil slot game has five columns, with three symbols each. It also comes with 1-10 pay lines that you can adjust. And, with a coin value range of between €0.01 and €10, the total stakes span from a min of €1 to €100. You change each value by tapping on their respective fields. Hitting Spin turns the reels once. But, you can activate auto spins by pressing the Auto button. It automatically starts up to 100 continuous spins. Enable Turbo mode to speed up your gameplay.

Symbols and Payouts

The Book of Oil video slot comes with ten symbols that display in the paytable (i) panel. Line wins count when you match two or three-plus symbols of a kind. The symbol matches must appear in adjacent positions of active pathways from the leftmost side to the right. But, scatter wins pay in any grid position. The symbol payouts within the pay table display as a reflection of the staked bet.

The typical values 10s, Js, Qs, Ks, and As are the lowest symbols. Manage three, four, or five of each kind to receive from 0.5x to 15x the total stake. Then, wands of Banknotes and Flammable Barrels are the medium symbols worth 0.5x to 75x for two or more of each type. The Derricks and a Suited Mogul consist of the highest-ranking regular icons worth up to 200x and 500x the selected wager for at least two.

A book that looks like a Safe is the scatter plus wild. As a latter, it stands in for all other symbols to help create winning combinations. As a former, it rewards 2x, 20x, or 200x for three to five of its type. During the Book of Oil free spins, the wild cannot substitute for special expanding symbols. Check the following segment for more details about the title’s extras.

Best Book of Oil Bonus Feature

This reel machine’s main highlight revolves around free games. The rounds trigger when you manage three-plus scatters on the reels and present 10 bonus plays. At the start, the game selects a random symbol that will expand for the entire feature. If enough special icons are available to complete a payout combination, the expanding feature activates to cover a whole column. Expanded icons reward combos of a kind in adjacent and nonadjacent reel tiles and only on enabled lines.

Grab the chance to improve your winnings significantly through the Gamble feature. In this Book of Oil bonus extra, you pick a card from the four dealt on the table facing down. The prize doubles if you beat the dealer’s card, and you can try again up to 10 times. Otherwise, you lose your risked wins, and the game ends. Press the Take Win to quit and collect your current winnings.

Play the free plays with expanding symbols feature using the Bonus Pop Buy feature at any time! But, this mode might not be available in all jurisdictions and casinos.
