Colossal reels is a special slot feature introduced by Williams Interactive (WMS) gaming publisher. On the same game-screen, gigantic reels feature two sets of reels: a small collection of reels spread over three rows - like a traditional video slot - and a then five-reel set of 12 additional rows. With so many reels at the same time in play, players will enjoy through 100 paylines and get a chance to score giant wins. Soon after first release, online versions of the gigantic reels slots have since begun to appear at some of the most popular online casinos. Two sets of reels are worked on with the colossal reels generator - a four-row main reel set of five reels - and a huge colossal reel set, with 12 rows and five reels. In total, there are 100 paylines on each and every spin to enjoy and win big.

Colossal Reels definition and meaning

Colossal Reels reels slots have been the best trend in casinos across the globe for many years. At one point, they were even more popular than such monsters as Cleopatra or Buffalo slots. Since their release they have been a huge hit and over time, their success has diminished a little, but they're still loved a lot and you'll still find them in almost about every casino you're walking into.

The original course featured titles such as Van Helsing and Forbidden Dragons containing 100 paylines, wild switch and extra content in the bonus slots.

What is so special about Colossal Reels

• Up to 100 paylines

• Stacked symbols on all reels

• Play on two sets of reels same time

• 'Transferring Wilds', which are similar from one set of reels to the other

The main advantage of stacked icons for players is ability to gain a lot of small wins regularly. It's the involvement of 'transferring wilds' that makes it a little more fun though. Most slots display Wild symbols - special icons that override all standard icons on the reel to aid in completing winning paylines. Many slots feature 'Stacked' wilds, which can fill a reel of two or three spaces.

Stacked Wilds appear in a gigantic reels slot, on the limited set of reels. However, if that happens the Wild transfers begin. On the large set of reels, the reel which is wild must 'switch' to the corresponding reel. Clearly then, you're looking at 12 Wilds taking up a whole reel of 12 rows on the wide reels.

Epic Monopoly II

For years WMS has released slots based on Monopoly, the popular table game. Nevertheless, Epic Monopoly II takes the Transferring Wilds and ramps up to 11. When the player crosses four Stacked Wilds on the main reels, Wild transfers will commence, making the accompanying ENTIRE mini-set reel Wild (for example, Reel 1 on the main set has four Stacked Wilds - all Reel 1 on the mini-set then turns Wild). This may mean twelve symbols going Wild on the second set of reels at once.

For retriggered spins, this means players could be looking at a limit of 100 free spins.

Sure, with two options to play - the Main Reel Pack and the Colossal Reel - and the Transferring Wilds optional bonus, there appears to be money ready to go. To really take advantage of that, though, you need to play at least 60 of those 100 paylines to have any impact on a budget. For several stacked symbols (and super-stacked on the Colossal Reel Set) you constantly play gambling on reaching loads of very unique combos.
