Slot Description

Double Rainbow plays out on 7 reels, each capable of holding 6 symbols. Instead of paylines, Hacksaw went with the cluster pays system in the game, which is common with candy-oriented games. As for wagers, bets fall between 0.10 to 100 coins per spin. For the wager of your preferred bet size, you can win incredible payouts, including the max win potential of 5,000x the stake. Although we have seen Hacksaw Gaming slots with higher payouts, this one does decently well for a medium volatility game (rated 3 out of 5 in variance).

Double Rainbow RTP is 96.38%, among the highest scores offered in Hacksaw slots. However, RTP is a theoretical value and might be way off the mark during the short run. Regardless, having such a solid score in any online slot is great. Equally noteworthy is the slot’s hit frequency of about 39%, which suggests a win within every 3 spins.

In most of our testing sessions, the hit frequency stayed true to its claim. Even though the slot was too vibrant and poppy for us, its simplicity and list of features were a delight. With Double Rainbow, everything is simple at all stages. Whether it is the gameplay or features, everything turns out neatly with a touch of overbearing sweetness. If the design is to your liking, then this one might hold high on your list. Although we felt Hacksaw went too far with the use of bouncy colors.

Theme, Design, and Sound

It is true sugar-filled games are much in rage, and one can almost forgive Hacksaw for following suit. Despite Double Rainbow being a candy-themed slot, it tends to overdo things. Given the potential Hacksaw stores, the design of Double Rainbow fell off the mark for us. The colors are far too vibrant, and the entire setting with a small pony, cotton clouds, and curvy rainbows might create a polarizing opinion. Some will adore it, while others might find these colors too overwhelming.

The sweet popping sound of the spinning candies and pleasant background score do not meddle with the gameplay but enhance the experience. However, the sound becomes pacy and too persistent with any feature running. We preferred the minimalistic approach in the main-game sound design. Overall, for the ardent fan of candy slots, Double Rainbow’s aesthetics, especially visuals, might be subject to polarizing opinions and heated discussions.

Symbols and Payouts

A combination of 5 matching symbols anywhere on the reels is the minimum requirement to land wins in Double Rainbow. Regarding symbols, the slot has 7 candies of different shapes and colors, all of which carry the same values. You can win symbol payouts worth anywhere between 0.10 to 50 x the stake by landing 5 to +15 matching ones in the game.

Among the special symbols, the slot has a wild logo. Wilds substitute for all paying symbols. Other than wilds, there are also cloud symbols that help the reels gain multipliers.

Features and Bonuses

Double Rainbow is not brimming with features compared to other Hacksaw slots. But the ones present offer ample scope to expand on the winning margins.

Rainbow Reels

As evident from the game screen, each of the 7 reels represents a rainbow color. Hitting a multiplier cloud on any reel activates a multiplier for that reel. The multiplier applies to any winning cluster having the same symbol color as the activated Rainbow Reel. Suppose a reel is already activated, and another multiplier lands on it. In that case, the multiplier from the new cloud gets added to the reel multiplier. Rainbow Reels reset after a new spin.

Multiplier Clouds

You can get two types of Multiplier Clouds on a reel: Normal Cloud and Double Rainbow Cloud.

Normal Cloud activates the reel multiplier upon landing on any specific reel. Possible multiplier values of a Normal Cloud are up to x250. An extra spin is also present with the Normal Cloud, where the Rainbow Reels remain activated.

The Double Rainbow Cloud also awards multipliers up to x250 but offers 3 additional spins where the Rainbow Reels remain active.

Full Rainbow

Activating all Rainbow Reels at once triggers the Full Rainbow feature. 5 extra spins are awarded during this feature, and all reels get multiplied by x2, x3, x4, x5, or x10 multipliers.

Bonus Buy

The Bonus Buy allows players to trigger 1 or 4 Rainbow Spins by 10x or 50x the bet, respectively.

  • The opting costing 10x the stake offers 3 activated Rainbow Reels with 4x starting multiplier and 1 respin

  • The option costing 50x the stake offers 3 activated Rainbow Reels with 4x starting multiplier and 4 additional spins.

  • The buy bonus option might not be available in some jurisdictions, such as the United Kingdom.
