Colossal Reels and Stacked Wilds

There are two main features offered by Colossal Reels Slots, one being the famous double set of reels, the other being stacked Wilds.

The first feature, the double set of reels, is easier to spot as it is there when you open your slot game. You will immediately see 2 sets of reels, the main reel set with a 5×4 grid and the Colossal Reel set with a 5×12 configuration. The combination of these two results in a stunning number of 100 paylines.

On top of that, Colossal Reels slots offer stacked Wilds, one of the features that dramatically increase the win potential of the game. On any given spin, you might land a stack of Wilds in the main reels set. It will then be cloned and replace symbols of a full reel in the Colossal set.

Premium Play and Free Spins

By landing 3 or more scatters/bonus (the balloon symbol), you will trigger the free spins bonus round. This will trigger the Free Spins Balloon Bonus Pick, meaning that you will see a screen with many ballons – you will have to pick among them, the number of picks depending on the number of scatter symbols you landed.

After the game is finished, you will be awarded a certain number of free spins and you will get to the next screen: the Free Spins Gamble. At this point you can decide whether to COLLECT your free spins or GAMBLE for more, you can get up to 100 free spins.

Finally, the feature begins and you will enjoy Mega Expanding Wilds, meaning that the wild symbols will expand on the main reels, and then be cloned and moved to the colossal reels set.

Curious about Premium Play? You can activate it during each and every spin, for a price stated by the slot. At this point, you will see a screen with 3 options – the highest of which offers Mega Expanding Wilds, a convenient Free Spins trail for winning extra spins and access to the Pick Me Bonus. Enjoy!
