The thrilling game mechanics that drive the Monster Wheels mobile slot put you in the driving seat when it comes to choosing how to play. The tasty top payout of 115,000 coins and generous RTP of 96.04% also make it a popular choice for Mobile Millions casino members.
The re-triggerable bonus round gives you the potential to claim stacks of free spins, and the win multipliers which can reach as high as 8x your stake can produce some seriously-good cash rewards.
Each time that you play the Monster Wheels slot on your mobile phone or tablet, you get to choose whether to take advantage of 128 ways-to-win or 288 ways-to-win. Depending on which option you go for, the structure of the reel set changes accordingly. And, the good news is that the prizes are worth the same regardless.
If you change your mind at any point or wish to see how the other game mode alters the playing experience, you simply need to tap the "Switch Ways" button in the centre of the screen between spins.
Microgaming has designed the reels to look like a car engine while the background features a tarmacked road with burning tyre marks.
You can create wins using thirteen different paytable symbols – the playing cards (N.B., 9, 10, J, Q, K, and A), the game logo, and the six drivers (Dracula, Frankenstein, the Zombie, the She-Devil, the Werewolf, and the Creature from the Black Lagoon).
The Monster Wheels logo represents the wild symbol, and it can only appear on the middle reel. The wild can contribute towards winning combinations by replacing any symbol with the exception of the scatter symbol.
Scatter symbol and bonus game:
Get ready to enter fifth gear when three of the petrol can scatter symbols land on the first, third and fifth reel of the same spin, because the Free Spins Choice feature will be initiated. Instead of awarding you a fixed or random number of free games, Free Spins Choice lets you choose which combination of free spins and multipliers you prefer. You can claim three free games with an eight times multiplier, six free games with a four times multiplier or twelve free games with a two times multiplier.
But, there's more in store as the Monster Wheels online slot also rewards you with one extra free spin each time that one petrol can symbol comes into view, two free spins each time that two petrol can symbols appear on the reels, or a second chance to pick from the Free Spins Choice feature if three scatters land on the screen.
