Colossal Reels Slots

There is no shortage of innovative slot machine configurations, and one of the most engaging ones you’ll come across is the colossal reels slots. These games provide an intriguing twist on a traditional play process. They have massive reel setups, rewarding features, and engrossing themes. This type of slot machine is becoming increasingly popular among seasoned and novice gamblers.

In most casino games, you’ll see a standard grid, often comprising five reels with three or four rows. But the colossal reels are, as the name suggests, colossal. They typically offer a twin-reel setup – a main 5×4 reel set accompanied by a colossal 5×12 reel set. That’s a whopping 100 paylines in total, significantly more than the usual 20–30 lines you find in regular games.

This larger than life setup not only increases the potential winning combinations but also makes the gameplay more immersive and exciting. The visual impact of two spinning reel sets side by side is undeniably impressive.

What Are Colossal Reels Slots?

Colossal Reels Slot Machines

Colossal reels slot machines, created by the game makers at WMS (Williams Interactive), put a fresh, big spin on classic games. In a nutshell, these slots have two sets of reels – a main one and an extra-large one. The main one generally has a 3×3 reel grid, while the extra-large one typically boasts a bigger 5×12 grid. So, you’re looking at more symbols, more lines to win, and ultimately, more opportunities to hit the jackpot and win real money.

Another aspect that makes colossal reels slots popular is their vast selection of themes. These games come in a variety of appealing themes ranging from ancient civilizations like Spartacus Gladiator of Rome, to magical adventures such as Giant’s Gold, and even popular culture themes like KISS: Shout It Out Loud!. Each of these themes is enhanced with great graphics and sound effects.

  • Stacked Wilds

The Colossal Reels slots are well-known for their Stacked Wilds feature. If the player lands a full stack of wilds on any of the main reel set, it’s transferred to the Colossal Reel set, filling the corresponding reel entirely with wilds. This mechanic dramatically increases the chances of hitting big wins.

  • Free Spins

Like any other slot game, free spins play a crucial role in these types of slots. Players can earn free spins, typically between 8 and 20, by landing scatter symbols. Depending on the specific game, these free spins might come with a multiplier, which can significantly enhance the winnings.

  • Transferring Wilds

When a wild stack appears on the main reel set, the wilds transfer over to the corresponding reel on the colossal reel set, covering it entirely. This feature boosts the player’s chances of completing multiple paylines and thereby enhancing the potential for substantial winnings.

Spartacus Gladiator of Rome

Get into the well-known WMS colossal reels. An immersive slot awaits, with combat sounds and Roman symbols setting the scene.

All winning paylines contribute to your prize, and soon you’ll be basking in the gold from your battles.

Giant’s Gold

What could fit the colossal slots better than a Jack and the Beanstalk theme? Bask in the tranquility of farm life, accompanied by animal sounds, while hunting for the golden egg.

When the spins are used up, you can gamble your winnings for a larger prize.

Li’l Red Riches

WMS colossal reels also venture into fairy tale themes. The grown-up Little Red Riding Hood is on her way to her grandmother’s house. Aid her in her safe journey, encountering familiar characters, and striving to reach the cottage.

Kiss: Shout It Out Loud

Ready to rock with the world’s wildest band? Kiss: Shout It Out Loud boosts the colossal reel slot machines’ fun with a rock concert atmosphere.
