Double Rainbow Slot Introduction

The Double Rainbow online slot game - developed and released by Hacksaw Gaming in March 2022 - is an exercise in how playful and charming a studio can design a slot. Clouds, unicorns, hard candy, and (of course) the eponymous double rainbow all make an appearance alongside bonuses like multipliers, cascading reels, respins, and more!

Double Rainbow Slot Game Background

Hacksaw Gaming is a studio responsible for many online casino games, encompassing diverse themes such as Aztec, Ancient Egypt, Halloween, and the great outdoors. Hacksaw even has slots based on the concept of the Rubik’s Cube, which is brilliant! The studio also likes its colourful and stylised slots, having developed and released quite a few in their time. And Double Rainbow might just be the most colourful and stylised of all!

Double Rainbow Slot Game Design

The Double Rainbow slot boasts a larger than usual 7-reel, 6-row game grid with cluster paylines and a potential max payout of 5,000x the stake; this sits alongside an exciting base game and a colourful array of bonus features. The slot takes you up among lilac-hued clouds with double rainbows and unicorns; the game grid takes up the centre of the screen and is filled with candy-like symbols. The reels - separated only by thin vertical lines - are floating in the air. The game logo sits on top of the reels, the O in RAINBOW glittering in a myriad of stars. The slot also boasts a wonderful audio presentation: a relaxed piano-based soundtrack plays when not spinning reels and tinkling star ambient sounds trigger when spinning them. Double Rainbow, then, is sure to have you up on cloud nine!

Double Rainbow Slot Mobile

Double Rainbow, like all the online slots on the Lottomart site, is available to play on desktop PC and mobile devices, including Apple, Android and tablets, so you can enjoy playing at home or while on the move. Also, why not download the Lottomart app via a stable internet connection or mobile data for great portability?

Double Rainbow Slot Symbols

The game has 10 symbols all fitting the theme of the slot to a tee!

The paying symbols look like shiny, colourful pieces of candy and have a payout of 50x the stake for 15-of-a-kind on the reels.

The slot’s Wild symbol is represented by the word WILD in rainbow colours in front of a thunderbolt. It substitutes for all paying symbols in the game.

Both the Normal and Double Cloud symbols activate whatever reel they land on with Reel Multipliers, adding multipliers of between x2 - 250x to said reel (or reels as the case may be) in the process. Normal Cloud symbols award an extra spin where all activated reels remain active. Double Cloud symbols award 3 extra spins where all activated reels remain active.

Double Rainbow Slot Bonus Features

Double Rainbow’s slew of bonus features will be sure to have you floating in the clouds!

Rainbow Reels

The slot's 7 reels are known as the Rainbow Reels - one for each rainbow colour. Each reel has a Reel Multiplier that's applied to all wins of the Rainbow Reel’s colour, so long as the reel is active. Rainbow Reels are activated when a Cloud symbol lands on it (see above section for more details). When a Cloud symbol lands on a Rainbow Reel, it reveals a multiplier value and adds it to the reel’s Reel multiplier.

Full Rainbow

This feature is triggered when all Rainbow Reels are simultaneously activated. All the Reel Multipliers get multiplied by one of the following multipliers: 2x, 3x, 4x, 5x, or 10x. The Reel Multiplier also grants 5 additional spins during which all activated Rainbow Reels remain active.

Cascading Reels

Achieving a winning combination requires landing five or more connecting symbols of the same kind anywhere on the reels. All symbols in winning combinations disappear from the reels, allowing new ones to drop in. This continues until no more winning combinations appear.

Double Rainbow Slot Summary

The Double Rainbow online slot is a solid entry by Hacksaw Gaming. Its highly stylised and colourful presentation may appear saccharine on the surface. Look deeper, however, and you’ll find a very unique slot based on the interplay of cloud symbols, rainbow reels, and multipliers. Both aspects make Double Rainbow stand out from the plethora of candy-themed slots. It also makes it a slot worth checking out. If you are a fan of the colourful thematics and graphics of this slot game, then you may find both the cosmic Starbust slot or the irish-themed Lucky Leprechaun slot enjoyable.
