Monster Wheels slot from Microgaming

Monster Wheels slot from Microgaming
In 2017 Microgaming released a real outlandish slot aimed at an enormous target audience, namely young-at-heart, car-loving players. In Monster Wheels, slot machine cartoonish Monsters are combined with the ’60s pimped American muscle cars and Rock music to top it all off. So far, that is slightly odd, but it’s mostly the gameplay that is definitely quirky. You can switch between non-standard grids with 128 and 288 win lines during regular spins, Wilds land only on reel 3, and Free Spins are offered in 3 modifications. We advise you to try the Thunderstruck Wild Lightning slot by Microgaming for free.

Besides 6 hilarious Monsters racing on the reels, there are the card suits to form the lower side of the paytable and a gasoline can that can get the Free Spins going when you land 3 of them at once. This Medium Volatility slot has an RTP of 96.04% and an impressive max win of 115 000 coins, so fasten your seat belts and start burning rubber with the Monster Wheels slot machine right away.

Personal testers’ opinion

This game left an indelible impression on us for a few reasons. The obvious non-traditional grid to begin with, of course. Then there are the original Monster Wheel symbols and the appropriate over-the-top rock music to go with them. There is plenty more to like about these wheels: as the monstrous potential - 115 000 slot coins, which calculated is 7666x the total bet (when playing with the max bet and having picked the FS with x8 Multiplier). Naturally, we were tempted to select the most volatile type of FS, but admittedly the best results we booked with the medium option via x4 Multiplier. The Free Spins were frequently triggered during our tests. Statistically, they are coming around every 84th spin, but you can see more of them if you play with the minuscule stakes. Also, the hit probability of the slot is high - around 35%, so get ready for many insignificant wins, but stay on the right gear, waiting for the Free Spins, which are just around the corner. Monster Wheels slot machine undeniably offers excellent entertainment. Still, when it comes to cover the bonus wagering requirements, it is stuck in the middle of the racing track (wagering points 5.63 out of 10), i.e. neutral advice to bonus hunters.
