Prime Casino players can now enjoy Blazing Rainbows, a colourful new exclusive slot from Playtech created in partnership with Rarestone. Combining rainbow-themed visuals, cascading prizes and Free Games features, the new release brings a bright and feature-led experience to the Prime Casino slots collection.
Now available for eligible UK players, Blazing Rainbows joins Prime Casino’s growing selection of exclusive online slots and limited-release games from leading providers.
What Is Blazing Rainbows?
Blazing Rainbows is a 5x5 online slot with 40 paylines and a minimum bet of 10p. The game centres around colourful prize symbols, overlays and cascading mechanics designed to create continuous reel action during gameplay.
One of the main features involves prize symbols landing beneath overlays to instantly award their displayed values. Winning symbols can continue cascading into position, creating additional opportunities for prizes to land during the same sequence.
This casino game also includes a Free Games feature. During Free Games, overlays can lock in place while spins continue, helping maintain prize opportunities throughout the feature round.
With cheerful visuals, a rainbow-and-pot-of-gold theme and straightforward gameplay mechanics, Blazing Rainbows is designed for players who enjoy colourful slots with accessible bonus features.
