Monster Wheels can mean only one thing – we’ve got a game that features race cars with those very wheels attached. A quick glance at the opening title screen for Microgaming’s slot game reveals this to be the case. This is yet another slot that features five reels, but it also brings into play a different selection of icons on each reel. They’ve gone for a 2-4-2-4-2 layout here, which is refreshing, and it also means you get 128 ways to win. However, if you would rather play with a 4-3-2-3-4 layout, thereby delivering 288 ways to win, you can choose to do so. That alone makes this one unusual slot, don’t you think? Monster Wheels comes with a red gasoline can as the free spins icon. This also has free spins labeled on the side. When three or more appear, you get to choose which type of free spins feature to play. You can go for the maximum 12 free spins if you like, and these will have a 2x multiplier in play. Alternatively, you could choose half that number and play just six free spins, but you get a 4x multiplier in this case. The final option is to choose three free spins, where a 8x multiplier is in action. Which one will you choose, and will you change your mind if you get to trigger those spins more than once?
