NextGen Oil Mania online slots: black gold runs through the casino

Slots pass free online like Oil Mania from Flash to the new HTML5 programming language is allowing us to rescue classic titles like this slot machine from 2013. But it also allows us to see how technology has evolved.
Thus, if in the part of the graphics the comic style is not badly achieved, the sound leaves a lot to be desired. Something that we have already seen with other titles updated to HTML5.

Game dynamics

The game dynamics are the usual in this class of video slots from the early 2010s We have a 5 reel screen for 3 spins and a total of 25 possible pay lines and 10 pay figures. These are divided between the real figures and the thematic figures. In the prizes, these figures can be grouped together making it easier for us to obtain a prize: 9 and 10, J and Q, A and K and The graph and the briefcase. These figures can appear mixed together in a line of 3, 4 or 5 figures. On the other hand, the car and the oil worker only give a prize in identical combinations of 2 to 5 figures in a line.
The bets can be made by regulating the total number of lines that we are going to play, from 1 to 25, and the total of credits per line that we are going to bet, from 0.01 to 10, with 250 credits per spin being the maximum. Something that will certainly attract players who want to make big bets.
In this online slot the return to the player is located in the middle zone with a 95.66% theoretical RTP.

Extras and bonuses

In this free online slot we find two bonus figures. The first is the Bonus figure, represented by the oil millionaire. This special figure appears only on reels 2, 3 and 4 and when it appears 1 to 3 times it launches the Upwild function.
During this Free Spins feature, the other bonus figure, the Wild, appears. Each time it appears in any position on the reels, it can occupy all 3 reel positions before disappearing. If another Bonus figure appears during the free spins, 3 more free spins will be added to the game.

Oli Mania online slots: our verdict

Simple is sometimes very effective, but in Oil Mania everything seems to us little. It is so much a slot machine that the years have fallen on, but it also does not have a particularly exciting game dynamics. The bonuses, which are the lifeblood of the game, have been difficult for us to achieve and the Free Spins round, even with the special feature Wild, has been somewhat monotonous.
