There are many online slots that offer a twist on the classic slot-spinning formula with features like cascading reels, sticky symbols, and even pick-me bonuses. But some gameplay mechanics stand out from these to offer you a truly unique gameplay experience. One of these exciting features is Colossal Reels — a gameplay mechanic from WMS Gaming that takes the traditional reel format and raises it to incredible heights.

Read on to learn what Colossal Reel slots are and which of these thrilling slots you can play at BetMGM. 

What Are Colossal Reel Online Slots?

Colossal Reel slots take the standard reel formula of three or five reels and create even more excitement by adding an extra set of reels. But these aren’t just another set of regular reels. Colossal Reel slots have a standard 5×4 reel and a 5×12 Colossal Reel. These additional reels enhance your chances of landing bonuses and even potentially a win each time you spin the reels.
