About Double Rainbow Slot

Hacksaw Gaming is a fast-growing game provider specializing in scratchcards, but also producing mobile-friendly slots. With the focus on new and innovative concepts and powerful themes, it aims to deliver entertaining gaming experiences.

Typically for this provider, the slot we review here has a bigger grid which is suitable for the Cluster Pays system. It is made of seven reels and six rows, while there are no fixed paylines. Wins are made by managing to land at least 5 matching symbols horizontally or vertically on adjacent reels.

The game comes with Multiplier Clouds, Reel Multiplier, and a Full Rainbow feature, but also cascades. Its maximum win potential can reach up to 5,000x the stake.

Design, Symbols and Graphics

Considering the candies on the reels, this is a food-themed slot, where you can see several shapes in different colours. In the back, there are rainbows, clouds and a unicorn, all in light colours pleasant to the eye.

Double Rainbow Slot

The gaming experience in the Double Rainbow slot is spiced up with a nice, relaxing and calming soundtrack. The symbols on the reels are starting to spin one by one, and when a win has formed the rest of the symbols get darker. Other animations are also used on the winning symbols like zoom-in effects for instance.

Moving onto the paytable there are seven candy-like objects to be the regular pay symbols. If you hit a cluster of five symbols, the minimum win is 0.1x the stake, while for 15+ symbols in a cascade this value can reach up to 50x the bet. This game also comes with wilds.

RTP, Variance and Payouts for Double Rainbow Slot

TheDouble Rainbow RTP is set at 96.38%, while there are other lower values available for the operators too. The game comes with medium volatility, potentially bringing fairly frequent but not very high rewards. To better understand how they work, you can take a look at our variance, volatility and RTP guide.

When it comes to the betting range, in this game the lowest value players can bet is £0.20 and the highest is £100. The maximum win potential is also solid and is up to 5,000x the stake.

Gameplay and Features on Double Rainbow Slot

Below we’ll explain all features of the game. The Double Rainbow slot also comes with two Bonus Buy options, but these aren’t available in the UK. So, let’s see the details of the other ones.

Cascades Feature

The basic feature in the game is of course the one related to the clusters. It removes the winning symbols and new ones drop from above which may lead to consecutive wins.

Reel Multiplier Feature

The reel multiplier is activated when a Cloud symbol lands and it appears in one of the seven symbol colours. If a reel already has a multiplier, the new value is added. These multipliers are used in wins of clusters with the same colour as the multiplier.

Multiplier Clouds Feature

Regular cloud symbols add multipliers to the reels with a value of x2, x3, x4, x5, x10, x15, x25, x50, x100, or x250 and award +1 free spin when all activated reels remain active. The Double Rainbow Cloud symbol adds x2, x3, x4, x5, x10, x15, x25, x50, x100, or x250 multipliers to the reel and +3 free spins.

Full Rainbow Feature

In the case of 7 active reels, this feature is activated as well and then all reel multipliers are multiplied by x2, x3, x4, x5, or x10. Five free spins are also awarded if all reels remain active.

Double Rainbow Slot on Mobile

The Double Rainbow slot is a mobile-optimised game, which you can reach through your mobile browsers on Windows, iOs and Android. No previous downloads are necessary and the game runs well on all of them.
