Endorphina have taken a different route with Book of Oil, instead of raiding Egyptian tombs for treasure, we go drilling for oil, also known as black gold.

Bets range from 10p up to £100 per spin, it has a medium volatility and an RTP of 96.05%.The design is unique for a book slot, inspired by rich oil tycoons. The action takes place on the edge of a desert with a city in the distance, with oil wells and various equipment for extracting oil.Symbols include the low value 10 Ace royal cards, oil barrels, oil pumps, wads of cash and the oil tycoon worth x10 –x500 for 5 matching symbols on a payline. The book is both the scatter and wild and substitutes all symbols.
Gameplay
The bonus round triggers after landing at least 3 scatter symbols for 10 free spins. One random symbol is chosen to become the special expanding symbol and when it lands it fills the entire reel.After any winning combination you have the chance to gamble in the hope of increasing the win. You’ll select one of 4 facedown cards on screen to try and beat the dealer. You can do this up to a maximum of 10 times. If you guess correctly your win is doubled but if the dealer wins you lose the winnings.The Bonus Pop option is available in some jurisdictions (not available in the UK), which allows players to buy into the free spins with a chosen expanding symbol, the cost is determined by your bet value and the choice of symbol.
Verdict
Book of Oil comes has a unique theme although it isn’t packed with features. The bonus round can prove to be lucrative depending on which special symbol is chosen and can lead to the potential prize of 5,000 the bet.
