Oil Mania is one of the slots by NextGen Gaming that meets the requirements for a standard online casino slot. It has five reels and three rows, and many standard symbols have been used. The sounds are quite enjoyable, but not good enough to bring the slot to the next level. Despite this, it is a fun slot in which it’s all about the oil, and the owner of the derrick. The latter is the wild and comes with an extra feature which definitely adds to the gameplay. A unique feature by NextGen Gaming, in an otherwise high-standard slot.
How to play Oil Mania?
Oil Mania is a standard slot in many regards, which is what you might expect from a slot by NextGen Gaming. It uses five reels and three rows, and it uses a large amount of the standard symbols. The nine until the Ace have been used to fill up this slot, and really, this is too large a number for a slot with a theme as this one.
That is, it would have been easy to think of some other animations, but apparently, the developer has paid more attention to the extra feature. The other animations relate to the riches that come from the oil business, apart from the employee that’s covered in oil and looks bored. The sounds support the slot, but they’re not special enough for us to recommend leaving the sound on.
The wild feature in Oil Mania
Oil Mania does not have free spins or a bonus game. A feature the slot does have is something like a combination of both. It’s easy to unlock this feature, and it can be combined to result in more wins over your previous wins. To unlock this feature, the only thing you need is the owner of the derrick. This is the wild and mobilizes the feature. You will directly receive a free re-spin in which the lowest row of the reel the owner was on becomes wild.
After this, you will receive another re-spin, in which the wild makes one position above it wild as well. Hereafter, you’ll receive a final re-spin during which one entire reel is wild. The feature really becomes interesting when you have a wild symbol on a reel next to another wild symbol. That is, you can make the second, third, and fourth reel completely wild. The free re-spins are great extras, especially when the wild symbols continue to expand during the game.
Pay lines on Oil Mania
Oil Mania uses 25 pay lines, but of course, you don’t have to play on all of them. You can adjust the pay lines at the bottom of the slot, or you can use the numbers alongside the slot. Pay attention, though, because the number of pay lines also does determine the success of the special feature. The game is also equipped with a gamble feature, which you can find left of the spin button, as well as the autospin function which is in the same place. This works exactly like in other NextGen Gaming slots and will continue to stay active during the feature. Of course, this conflicts with the gamble feature, which thus cannot be active during autospin mode.
