The graphics aren’t 3D but they are still well designed and detailed, placing you right in the centre of the action. And with 25 paylines and some special features too, there’s chance to win cash prizes. But will you manage to drill right into the stream of money? Here’s a review of Oil Mania from NextGen with all of the facts you need.

Find Your Fortune

The gameboard is set right in the centre of the screen with five reels and a maximum of 25 paylines. These are flexible which means you can opt to play on fewer if you prefer, using the buttons at the base of the screen. You’ll also need to decide how much to wager per line, from the entry level of 0.01 up to the limit of 10.00 per active line. This provides a total max bet of 250.00, dropping down to the total min bet of just 0.25. There’s a medium variance for this game and an RTP of 95.66%.

Strike it Rich!

While you’re focussing on the main reels to try and line up matching symbols, keep one eye open for the extras on the gameboard as these could give you prize haul a real boost. Unlike a lot of other slots, there’s no wild as standard on the reels, but if you land the Oil Tycoon you’ll unleash the special Upwild Feature. You’ll only need one of the oil tycoon symbols to appear on reels 2, 3 or 4 and you’ll receive three free spins. During each of these free spins, the oil well will spurt upwards covering a further one of the tiles each turn with a wild. This means that during the first spin you’ll have one wild, the second will give you two and during the final third free spin you’ll have three wilds. You can retrigger this feature during the free spins; if this happens the oil well moves over to the new reel and the number of free spins resets to three.

If you’re feeling brave and really want to try for a big win, there’s also the Gamble feature which becomes active after every regular win. With this option you take your prize that you’ve just won and gamble it for the chance of either doubling or (if you’re feeling particularly adventurous!) quadrupling it. It’s a simple game of luck where you either have to predict the colour of the next card (to double your prize) or correctly choose the suit of the card about to be turned over (to win x4 your prize). The rules are very easy: if you guess right you get to increase your prize and can gamble again if you choose, but if you get it wrong you forfeit your money completely. It’s not a game for the fainthearted and is an entirely voluntary part of play.

Become a Tycoon

If the “black gold” has got you hankering for more, you might be surprised to learn that oil is the theme on a number of games from different developers. You’ll have plenty to pick from but you could give Gusher’s Gold from Rival a try. There are 5 reels and 20 paylines and your job will be to try and drill in the right place to hit an oil stream. There’s an Oil Pump jackpot, free spins and bonus rounds too so there’s a very good chance you will hit the big time.

Hit the Money

Oil Mania from NextGen is an online video slot which is all about hitting a liquid stream of cash by drilling to find where it flows. The wild feature is a fun addition to the reels but to take play up to the next level it could do with the addition of a proper bonus round. In its current form it’s simple enough to be enjoyed by both newbies and the more experienced alike.
