Microgaming's Monster Wheels slot comes with unique Ways to Win options

How will you choose to play? That is the question you have to ask yourself before you even set the reels spinning on Microgaming's new Monster Wheels slot and it is a decision you should not take lightly as it can affect how your game plays out.

Your options are in the makeup of the reels, which can be a 2-4-2-4-2 set up, or a 4-3-2-3-4 set up. The first option gives players a total of 128 Ways to Win on each spin, while the second option gives players more symbols, but a total of 288 Ways to Win on each spin.

The number of ways won't affect your stake size, but will affect how the reels look and play. Add to this a choice of three different free spins features when you trigger the bonus round, and the Monster Wheels Wild offering you a chance of even more pay outs when landed on the reels and you have all the ingredients for a slot game that will have you roaring with delight.

Let's take a look now at how the game shapes up in more detail.

The presentation of this slot is cartoon style and in truth, it reminded me greatly of the Wacky Races cartoon of my youth, which is not a bad thing at all. The music is somewhat loud and a little in your face at times and after a while, it had me reaching for the mute button to be brutally honest, but with the volume a little lower it is an enjoyable accompaniment to the game. Once you have selected your Ways to Play, the reels will adjust to your chosen set up and you can then choose your bet stake from the options below and click the Spin button to get things under way.

What is on the reels?

On the reels are the usual playing card symbols as the lower value symbols in the game and these offer considerably smaller wins than you receive if you can land some of the Monster Wheels competitors as the winning symbols. Each of these six symbols, all of which are cars in the race, offer the same cash prizes and also offer pay outs for just 2 symbols on a pay line, as opposed to three.

The cartoon styled graphics of the higher value symbols are very nicely done but the playing card low symbols are rather dull and do look somewhat out of place on the reels to be honest. There are two other symbols on the reels, the Wild and Scatter and these unlock some of the key bonus features of the game.

Wild features

The Monster Wheels symbol is the Wild and when you land this it can substitute for any of the lower value or higher value symbols on the reels to create one or multiple winning pay lines. The more Wilds you land on the reels, the better chance you have of landing a greater value win, but it has to be said at times it can be difficult to land just one winning Wild, let alone several, such is the higher variance nature of the slot at times.  Part of the reason for that is that the Wild symbol only appears on the third reel and whatever way you decide to play, that reel only ever has two symbols on it.

Free Spins features

Three of the Gas Can scatter symbols across the first, third and fifth reels on a single spin triggers the Free Spins Choice bonus round. Here you get to choose which of the three available free spins games you want to play. They are:

  • 12 Free Spins with a 2x multiplier on all wins.
  • 6 Free Spins with a 4x multiplier on all wins.
  • 3 Free Spins with an 8x multiplier on all wins.

Regardless of whatever Free Spins bonus round you select, if you land any additional scatter symbols on the reels during the bonus spins, then you receive an additional free spin for each scatter you land. If you can land three scatters once again during the free spins bonus round then you will re-trigger the free spins bonus game completely.

Best feature of the Monster Wheels slot

While being able to select your reel set up is a new development in slots and does give the players more freedom of choice in how they want to play, it actually doesn't help the player achieve more wins as that crucial third reel is only ever two symbols high. As such, I tend to find that playing the most pay lines option as the better value. The Free Spins games however are the best feature of the slot but they do have huge variance in how they play, the more free spins you pick, the lower the variance, so be wary of that 3 Free Spins 8x multiplier option as you can find that this pays out some massive wins, as well as some very low wins too.


There's been plenty of innovation and thought gone into the Monster Wheels slot. The free spins choice is a good one and although the game plays medium to high volatility, it can offer players some great value wins!
