Double Rainbow Bonus Buy Slot – Overview

Double Rainbow is a fun, enchanting non Gamban slot title that takes you on a vibrant journey across the skies and through rainbows with a colourful Unicorn. What sets this aside from a lot of other games is the feature which allows you to buy the bonus for a set fee. Here is a detailed review of everything Double Rainbow slot has to offer.

Gameplay Features and Mechanics

‘Double Rainbow’ comes with a set up of 7 reels, 6 rows, cluster paylines and has a maximum win of 5000x. Winning combinations form when clusters of symbols appear in groups, with cascading reels adding extra excitement. Each win removes the winning symbols allowing new ones to fall in their place and potentially create chains of winning clusters.

The game’s symbols are just as whimsical as its theme, featuring a variety of rainbow coloured gems, stars, clouds and smiley faces. Every win brings cheerful animations, adding to the game’s lighthearted charm which is hugely popular with women.

The Bonus Buy Feature

If you decide to pay a set fee of 100x your stake you can instantly get onto the bonus feature which is where the biggest wins happen. This feature is hugely popular at non UK casinos especially with UK players who cannot buy the feature at UKGC regulated casinos.

How It Works:

  • Rainbow Bonus Round: Purchasing the bonus buy option takes players directly into the Rainbow Bonus round, where reels fill with rainbow multipliers and high paying symbols. It will cost you 100x your bet stake.
  • Colour Multiplier Wheel: During the bonus round players encounter the Colour Multiplier Wheel. This wheel adds a multiplier to any rainbow colours that appear on the reels and these multipliers are cumulative, meaning they stack with each spin. Each time a rainbow colour appears, the corresponding multiplier is added to the winnings, creating the potential for life changing wins/payouts.
  • Expanding Rainbows: With each winning cluster, new rainbow colours and multipliers are added to the reels. The more clusters players land, the more rainbows appear, filling the grid with expanding multipliers that significantly boost the total win potential, this is how you can achieve the games maximum win of 5000x.
