Move over Wacky Races because Monster Wheels is set to help you sail past the chequered flag and onto victory in a madcap monster-themed slot from Microgaming. With dynamic playing features that let you pick your favourite free spins feature and choose between two game modes, the slot gives you more control than most. The guest stars include plenty of famous faces including Frankenstein and Dracula, and all six racing drivers have the potential to score you big cash prizes.

Our verdict:

Monster Wheels is a five-reel Microgaming slot that doesn't use a traditional payline setup. Instead, it offers you two game modes, the first of which lets you create winning combinations in 128 different ways and the second of which lets you create winning combos in 288 ways. The cartoon-style graphics make the monster theme both amusing and entertaining, but it's the multiple choice Free Games Feature that makes this online slot a real winner! You can play the game with a range of bet sizes, starting at 30p per spin and allowing for a maximum of £15 per spin. The RTP (Return to Player Percentage) is also a very respectable 96.04%.

Design:

The Monster Wheels slot boasts colourful graphics and animations, as well as a suitably spooky soundtrack.

The racetrack background includes flaming skid marks while the reel set contains a variety of symbols including a petrol can, the game logo, six racing drivers (a werewolf, an amphibian-type monster, Dracula, a female devil, an Egyptian mummy, and Frankenstein) and six playing card symbols (N.B., 9, 10, J, Q, K, and A). 

The layout of the reels is influenced by which game mode you choose. For example, if you pick 128 ways to win, Reels 1 and 5 are two-rows-high, Reels 2 and 4 are four-rows-high, and Reel 3 is two-rows-high whereas if you choose 288 ways to win, Reels 1 and 4 are four-rows-high, Reels 2 and 4 are three-rows-high, and Reel 3 is two-rows-high.

Wild symbol:

To help put you in front of the competition, the Monster Wheels online slot includes a wild symbol, which is the tyre symbol featuring the game logo. It can land on Reels 1, 3, and 5 where it has the power to replace all symbols except scatters whenever it can contribute towards a win.

Bonus feature:

The bonus feature in Monster Wheels is particularly exciting not to mention noteworthy as it allows you to choose your favourite free spins/multiplier combination. You can pick three free games with an 8x win multiplier, six free games with a 4x win multiplier or twelve free games with a 2x win multiplier. To trigger the bonus, you'll want three of the red petrol can scatter symbols to appear on the first, third, and fifth reel.

If during the bonus game, one occurrence of the petrol can symbol shows up again, you gain one extra free game, and if two petrol cans appear on the same spin, you get two additional free games. Ideally, however, you'll want to see three scatters land on Reels 1, 3, and 5 as this retriggers the feature, giving you the option to pick your preferred free spins/multiplier combination once again.
