What Are Colossal Reels?

Rainbow Riches Reels of Gold is unique because it uses this WMS game mechanic that was first invented for offline slots in bricks and mortar casinos. In Colossal Reels games there are TWO set of reels, both 5 reels wide. However, whilst one set has 3 or 4 rows, the other set has a total of 12 rows. This increases the win potential significantly.

Features of Colossal Reels:

  • In Colossal Reels games the paylines are increased to 100.
  • Stacked Wilds can appear on any reel.
  • Transferring Wilds may move across from the main reel to the 12 row set.

Colossal Reels also appear in the slots, Spartacus Gladiator of Rome, Giant’s Gold and Epic Monopoly.

Rainbow Riches Reels of Gold RTP Variations

When playing Rainbow Riches Reels of Gold it’s important to understand that the RTP (Return to Player) is different depending on the stake level. At under £2 the RTP is 94%. Playing at over £2 increases the RTP to 96%. And playing with a Big Bet Option increases it still further to 98%.

The variance in Reels of Gold is around medium.

Rainbow Riches Reels of Gold Theme and Symbols

In this version of Rainbow Riches we everything we are used to in the Pots of Gold format, with the same symbols and the recognisable logo. So we get 4 leaf clovers, horseshoes, harps, mushrooms and rainbows. And of course there is the Lucky Leprechaun who is the best premium symbol, triggering a 500x payout for five on a payline. He also comes in stacks on the reels.

Reels of Gold Gameplay

The Colossal Reels set up for Reels of Gold makes for some exciting gameplay as symbols stacks transfer across and create big wins. So when you play, look out for stacks of Rainbow Riches symbols – they also become wild when they are part of a winning payline, so stacks of wilds can transfer onto the big reel set.

Here’s some more features to look out for:

Mini Features

There are 7 mini features which can be triggered by the random appearance of the Magical Fairy. They are as follows:

Super Stacked Wilds: The fairy turns one or more of the main reels into Rainbow Riches stacks which turn wild and transfer to the Colossal Reel set.

Magic Wilds: Magic Wilds appear on the reels and slide up and down before locking into position.

Wild Burst: Butterfiles land on the reels, transforming symbols into wilds.

Wishing Well Bonus: Any heart, diamond, spade or club symbols turns into a wishing well symbol which can then transform into premium symbols.

Reel Win Mulitpliers: A multliplier of 2x to 5x is applied to your winnings.

Near Miss Free Spins: Get 2 free spins bonus symbols and get a boost from the fairy to add more to trigger a free spins round.

Near Miss Win: The reels shift to create a guaranteed winning combination.

Free Spins Round Feature

There is of course a free spins round in Reels of Gold. You must land three or more balloon bonus symbols to trigger it.

3 Balloons: 10x multiplier and 1 pick from 3 balloons.

4 Balloons: 25x multiplier and 2 pick from 4 balloons.

5 Balloons: 200x multiplier and 3 pick from 5 balloons.

6 Balloons: 200x multiplier and 4 pick from 6 balloons.

Gamble for more spins … it is also possible to gamble for more free spins after you have done your balloon pick. When you gamble you must wait to see where the marker lands on your chosen dial. Green indicates more free spins, but red means you bust and you must go back to the base game!

Big Bet Mode Feature

There is also a Big Bet Mode with enhanced features, depending on which level you play at: 

£10 Level– Any Wilds that land on the main set will transfer over to the Colossal Reels and expand to fill an entire reel.

£15 Level – Same as the £10 level, but get 7 bonus symbol icons to earn between 10 and 50 free spins.

£20 Level – Again, wilds transfer and expand, but this time get between 15 and 50 free spins with 6 bonus symbols.

£25 Level – Wilds transfer to the Colossal Reels, but in this instance getting just 5 bonus symbols earns you between 20 and 50 free spins.
