There are many monster-themed mobile slots about, but none quite like Monster Wheels, which sees five fearsome fiends get behind the wheel of a racing car to take you on the ride of your life!

This light-hearted mobile slots game from Microgaming boasts amusing images and animations of characters like Frankenstein, Dracula, a werewolf, a she-devil, and an Egyptian mummy who are ready to burn rubber and help you pass the finish line with big cash prizes.

Our Verdict: Monster Wheels is a five-reel mobile slots game that gives you a choice of 128 ways-to-win or 288-ways-to-win. Better still, picking 288 ways-to-win doesn't cost you extra, and you can switch game modes at any point should you change your mind.

As flames lick the scorched racetrack behind the reels, you'll see the six racing drivers who are the highest-paying symbols in Microgaming's Monster Wheels appear on the screen. They can be joined with up to seven more paytable symbols, including the game logo, 9, 10, J, Q, K, A, and petrol can.

To make the playing experience even more fun, there's a funky Halloween-inspired soundtrack that plays while the reels are in motion.

A couple more benefits of this Microgaming mobile slots game are that it boasts a superbly generous RTP (Return to Player Percentage) of 97.00%, and the most you can win is an impressive 7,680 times your stake!

How to Play: Playing the Monster Wheels slots game on your mobile phone or tablet is pretty simple. You start by choosing whether to play it with 128 or 288 ways-to-win, then you pick an amount to bet-per-spin. N.B., to adjust the size of your stake at any time, just tap the plus or minus button under the box marked "Bet". You can choose a minimum of 30p and a maximum of £15, which means that this slot is perfectly suited to both low and medium-stakes players.

Wild Symbol: To help you fast-track your way to big prizes, there's the wild symbol which is represented by the game logo. It's only ever present on the middle reel, and it can replace all symbols except the scatter symbol to create winning combinations.

Free Spins Bonus Round:

To unlock the Free Spins Bonus Round in the Monster Wheels mobile slots game, you will need three of the scatter symbols (which are represented by red-and-yellow petrol cans) to land anywhere on the first, third, and fifth reel.

In the first stage of the bonus game, you're prompted to choose one of three options. You can choose to take three free spins with an eight times multiplier, six free spins with a four times multiplier or twelve free spins with a two times multiplier.

Once you've made your selection, you can start using your free spins. But, you'll win one extra free spin every time a petrol can symbol comes into view, two free spins each time two petrol can symbols land anywhere on the reels, and a completely new set of free games when three petrol can scatters appear on the reel set.
