Colossal Reels Online Slot Games

There are many gaming features out there that set apart certain slot providers from the rest. Often these ‘specialities’ are trademarked in name, but sometimes in function too. Of all of these, one of the most stand-out features in the online slot gaming industry must be the Colossal Reels slots feature, which was traditionally introduced and trademarked by WMS.

Having originally found their stage on land-based casino slot machines, WMS has transferred some of their more affluent games titles to their online platform of games. Some great examples of colossal reels slots include games like Forbidden Dragons, Giant’s Gold, Lil Red Riches, KISS – Shout it out loud, Rainbow Riches, and Spartacus.

More about Slots with Colossal Reels

Though many slot providers offer giant reels sets for gameplay over a vast number of paylines, traditionally, however, Colossal Reels slots are a WMS Gaming invention played over up to 100 paylines.

Conventionally, the game includes a thematic game screen that holds two-reel sets. The first is a 5x3 grid reel setup, and the second is a massive 5x12 reel setup - hence the name “Colossal Reels”. It allows for an above-average chance of winning if you play the full range of paylines. This can work out quite expensive on a maximum bet of €5 per line but will prove rather lucrative when matches are made. This may appeal to high rolling slot players.

Common Features on Colossal Reels Slots

There are two prominent special features that are found on colossal reels games across the board. These include:

1. Stacked Symbols

The giant reels sets will often be laden with stacked and super-stacked symbols to help provide wins over the multiple win lines.

2. Transferring Wilds

This symbol acts as a regular joker and substitutes for all standard game symbols to help complete winning combinations, but there is a twist. If a stack of Wilds appears on the main reels, the transferring wilds will clone themselves onto the same reel number on the colossal set to bring in bountiful rewards.

Look no further than our CasinoWow Colossal Reels Slots list to find a game with giant pay-offs and big entertainment value. If you are still not sure about spending money on such slots, check out our list of slots in free play mode.

Frequently Asked Questions

The colossal reels feature is a Williams Interactive (WMS) invention. Originally, in Colossal Reel Slots, you had two sets of reels on the same game screen, the first set with 4 rows and 5 reels and a second set with 12 rows and 5 reels, with up to 100 paylines. Colossal reels can also be defined by large symbols expanding multiple rows on the reels.

Spartacus Megaways by WMS, a classic example of a colossal reel Slot with 100 paylines, Secrets of Atlantis by NetEnt, an enchanting underwater-themed Slot with 40 paylines, and Opal Fruits by Big Time Gaming, a unique space Fruit Slot with tumbling reels, are among the most popular Slots with this feature.
