Monster Wheels Slot Review

Released: October 2017

The Monster Wheels slots game can be found at Microgaming casinos. Microgaming as a standard now publish the slots house edge information of all their games at any online casino that holds a UKGC license (this is a requirement for all UKGC licensed casinos. As such we can say that the House Edge of Monster Wheels is 3.96%. When playing at any venue that does not hold a UKGC license and does not specifically publish the Return to Player information for their game, this information should be used as a guideline only as we cannot confirm whether or not this game is configurable.

Some people just shouldn’t be on the road.

Monster Wheels is a 5 reel game that does not use standard paylines. Instead any three or more matching symbols in any position on adjacent reels starting from the left side of the reels constitutes a win. It has a non-standard reel layout. In the first layout reels 1 and 5 are four symbols high, reels 2 and 4 are three symbols high and reel 3 is two symbols high. This is equivalent to 288 standard paylines. In the second layout reels 1, 3 and 5 are two symbols high and reels 2 and 4 are four symbols high. This is equivalent to 128 standard paylines. The player can select which reel layout is currently in play.

The ‘Monster Wheels Logo’ symbol is Wild and only appears on reel 3.

There is only one bonus feature when playing Monster Wheels and it is activated when you receive 3 or more of the ‘Gas Can’ scatter symbol anywhere on the reels. When this happens you will be given the choice of the following bonus options:

- 12 free spins with all wins doubled.

- 6 free spins with all wins multiplied by 4.

- 3 free spins with all wins multiplied by 8.

During the free spins if you receive one or two Gas Can scatter symbols you will be awarded 1 or 2 additional free spins respectively. If you receive 3 or more Gas Can scatter symbols you will retrigger the bonus selection you made.


Monster Wheels is a game of contract. On the one hand, the unique reel layout and ability to select your preferred layout is unquestionably novel and interesting. On the other the bonus feature is bland and the House Edge is on the higher end of the modern games being released. Overall we’d still say that Monster Wheels comes out a winner, but it was a close race.
