Description of the Slot 

Think of the wonder the sight must have caused when a Californian, Paul Vasquez, filmed a double rainbow from his front yard. But what appears to be a rare spectacle of nature is a pretty common phenomenon. Scientists explain that a rainbow is almost always double; it’s just that the second one is usually so faint we can’t perceive it with our naked eyes. Nevertheless, Hacksaw Gaming didn’t let go of the opportunity to seize the magical appeal of this phenomenon in its 2022 slot, Double Rainbow. 

Double Rainbow is played on a 7×6 grid layout with cluster pays mechanic. With wagers spanning from 0.10 to 100 coins per spin, players need at least 5 matching symbols in a cluster to win payouts. Although payouts vary on the type and number of identical symbols you land, at its best, the slot can shell out up to 5,000x the stake. Another impressive number that pops out of the game is its RTP of 96.38%, which hovers safely above the industry average. With a bunch of exciting features hiding within its colors, let’s check out what Double Rainbow brings to the table. 

Design and Audio

Double Rainbow is a cutely animated slot with too many colors popping out of the screen. While Hacksaw Gaming has earned a reputation for creating visually stunning slots, the graphics in Double Rainbow might be a bit too much for some players. 

The reels are transparent with colorful candy-shaped icons fashioned as pay symbols. A unicorn pony stands next to the grid, rendering a magical charm into the game. Of course, the two rainbows are present behind the reels, but they look more like colorful water slides than bow-shaped rainbows. Also, a melodic piano tune accompanies the visuals and is quite soothing to hear. 


Even though Double Rainbow doesn’t feature loads of features we usually find in other Hacksaw slots, the game still has plenty going on to keep you thoroughly engaged. 


Whenever a winning cluster lands, symbols from the cluster are removed and substituted by new ones. If the fresh symbol formation results in another win, the reaction feature repeats. 

Rainbow Reels

Like the seven colors of a rainbow, the slot is composed of 7 reels representing each rainbow color. When a cloud symbol appears on a reel, it reveals a multiplier for that specific reel. The multiplier applies to all winning clusters with the same color as the rainbow reel. If a reel is already activated with a multiplier, another cloud symbol dropping on that reel adds to the multiplier. 

The game has two types of multiplier clouds: normal and double rainbow clouds. While both cloud symbols provide multipliers worth x2 to x250, normal cloud awards +1 extra spin, and double rainbow cloud offers +3 spins where all activated reels remain active. 

Full Rainbow 

Once all seven reels become active, the Full Rainbow bonus feature gets triggered. The feature starts with all the reels multiplying by x2, x3, x4, x5, or x10. Additionally, you get +5 additional spins where all reels remain active. 

Bonus Buy

Provided this feature is available in your region, you get two options in the bonus purchase menu: 

  • The first option costs 10x the stake and gives 1 rainbow spin with a guaranteed respin and three activated reels. The reel multiplier for this option starts at x4
  • The second option costs 50x the stake. It provides 4 rainbow spins with three activated reels and reel multipliers starting at x4

Payouts, Theme, and Volatility

The slot’s paytable consists of 7 candy symbols, all offering the same payouts. Hitting at least 5 matching symbols qualify you for payouts by offering 0.1x the stake. However, a cluster comprising 15+ matching symbols awards an impressive 50x the stake

As the title suggests, Double Rainbow focuses on a natural phenomenon where instead of one, two rainbows appear. However, the game bears an animated design with a touch of magical flair to it. 

Double Rainbow has medium volatility, which suggests a balanced-out risk model of frequent winnings with mostly low to average payouts. 

About the Game Provider 

{{ content }}

Hacksaw Gaming entered the online slots industry in 2018. Initially, the company focused on creating scratchcards but soon shifted its attention to online slots. Currently, the game provider has just over 40 slots in its portfolio. But each of these has been meticulously crafted with unique visuals and excellent features. Hacksaw Gaming slots are widely available across numerous European casinos, including several top-tier Bitcoin and Ethereum gambling platforms. 

Final Considerations 

Double Rainbow is neither the most visually appealing Hacksaw Gaming slot nor the most feature-packed. Its volatility levels are also pretty moderate, and the max pay size is decent enough. While an impressive RTP and rainbow reels feature surely add to the game’s plus points, there are better Hacksaw slots out there that offer more engaging gameplay.

But if you are looking for a cute mid-variance slot that can churn out lucrative payouts without too many complicated features, Double Rainbow is indeed a title worth considering.
