Coin denominations in this slot range from 0.10 up to 10.00, which is most certainly pretty standard for a classic slot. Up to three coins can be staked on the games single payline, making the minimum and maximum wagers of 0.10 and 30.00 per spin, rather easily to calculate.
As mentioned, there are actually a couple of special features in this classic slot machine game. Two or more red gas tanks will trigger a total of 7 free spins, with all winnings offered 3x multipliers. Should a player spin 3 of the red gas tank icons, they’ll land 21 free spins, again with 3x multipliers. The octane gas canisters are also wild symbols, and they have the power to substitute themselves for any other icon, with the exception of the red gas tank scatter symbols.
