Colossal reels are a special type of slot reels that are found in very few slot machines. Colossal reels were first developed by the software Provider Williams Interactive (WMS). Characteristic of this type of reels, which are also called colossal reels, is that simultaneously played on Slot machines with a high number of reels. Consequently, the number of paylines in slots of this type is also significantly higher than in conventional slot machines on the Internet. One generally speaks of "colossal" when something is of unusual size or impressive force.
A very popular slot with colossal reels is the Kiss™ slot from WMS. Here, there are two sets of reels at once. Besides the main set, there is also the colossal set. More specifically, the main set has a 5 x 4 grid and the colossal set has an additional 5 x 12 grid. This results in a total of 100 different paylines. By the way, in this slot, extended wilds are transferred to the colossal reels, so there are impressive winning chances in this case.
