This online slot machine will take you into the XIXth century – the time when wildcatters were trying to find petroleum in the western areas of the American continent. Rigs and steam engines in the field are depicted in the game’s background. On the five reels, you’ll see a gold car, a petroleum worker (the most paying symbol), a stock market graph, a suitcase full of money and traditional poker suit icons ranging from nine to Ace. The playing process is accompanied with folk music of Wild West, bird songs and sounds of different mechanisms which are used in petroleum exploration.
Tycoon symbol only occurs on reels four, three and two and launches the Upwild feature. It consists of three free spins in which an animated Oil Well symbol appears on the lower row. Oil Well grows upward by one position with every free spin three times then disappears; it acts as a wild and may substitute for all other symbols. The Upwild feature may be retriggered if the additional Tycoon appears. Wins achieved in free play mode are added to the main winnings.
Oil Mania slots game has a gamble feature which allows a user to gamble his winnings. For that end, he should guess colour (red/black) or suit (diamonds, hearts, spades or clubs) of the next card from the deck. If a gambler guesses a color, a prize is doubled, the right choice of card suit increases winnings by 4 times. But if he fails, he completely loses all wins. Prizes may be gambled up to 5 times.
