Along the bottom of the screen, is your wagering menu bar. Players can choose coin values that range from 0.01 up to 2.00 per coin. Only one coin per line can be wagered, but players can adjust all 25 of the paylines if they wish. Minimum and maximum wagers are fixed at 0.01 per line, per spin; and 50.00 per spin respectively.
The main special feature in Oil Mania is the Upwild Feature. When the Oil Tycoon lands anywhere on the second, third and fourth reels, the player will get 3 free spins. They will also get the privilege of watching the oil well explode from below the reels, which will grow further up the reels with every spin. For instance, on your third free spin, it will have created an expanding wild across an entire reel (or reels). The feature is easily retriggered when another Oil Tycoon icon appear on the reels.
The Oil Tycoon icon is the only special feature in this game, but it is such a good one that players won’t really need anything else to cheer them up! Oil Mania is unique and creative in that respect.
