Double Rainbow Slot RTP, Details & Wager Limits
The Double Rainbow slot is played on a 7×6 grid and uses the Cluster Pays mechanic. All you need to do to land a winner is match 5 or more connecting symbols anywhere on the grid. The way the mechanic works is that winning symbols are removed and new ones drop in. This continues until no more winners are formed.
Stakes range from as little as 20p and as high as £100 per spin, thus catering for all bankrolls. As is the case with all Hacksaw games, just use the arrows to the left of the spin button to increase or decrease your total bet. Turbo spins and autospins are also available for players outside the UK.
The Double Rainbow RTP is 96.38%, which is generous and above the average figure for an online slot. The hit rate is really promising too at 39.49%, which means that well over a 3rd of all spins on average will result in a winning cluster.
The maximum win is 5,000 x your stake, which isn’t too bad when you consider that there are many slots out there under this figure. It’s not as high as the 10,000 x norm for Hacksaw games, but it’s still pretty good.
Theme – fluffy clouds, unicorns, and rainbows
The theme in this Double Rainbow slot game is all about unicorns, rainbows and bright colours. It may not suit everyone and is probably aimed more at the younger players. Although if you’re still a kid at heart then this may well still be great for you.
The reels are set in the sky among the clouds, with a unicorn to the left of the reels that looks a little like an old school My Little Pony figure. The design is very simple but the bright symbols and the glittering logo above the reels certainly help keep your eyes glued to the screen.
The soundtrack is rather calming and doesn’t really have any distinct theme to it. The sound effects are nice when winning clusters are formed, and the music goes up a notch once the bonus feature lands and extra spins are in play. Overall, it’s nice enough but it won’t win any awards.
One the reels, you’ve got many different coloured shapes – a red square, an orange circle, a yellow triangle, a green heart, a blue star, a pink moon and a purple flower. All symbols pay the same amount, which is different. Land 15+ of any matching symbol to enjoy a 50x payout.
The game’s Wild is a lightning bolt and substitutes for all paying symbols.

Double Rainbow Mobile
The Double Rainbow slot game has been produced using HTML5 technology as part of Hacksaw’s Pocketz series and is great on mobile and tablet devices. iOS and Android devices are absolutely perfect in terms of compatibility, and the Cluster Pays setup works really well on smaller screens.
Double Rainbow Bonus Features
There are 5 bonus features here ranging from numerous multipliers to extra spins. You can also buy some additional spins for a certain price if you’re outside the UK. Let’s explain how each of the exciting bonus features work.
Rainbow Reels feature
There are 7 reels in the game, which means that there are also 7 rainbow reels, one for each colour of the rainbow. Each Rainbow Reel has a Reel Multiplier that is applied to every win of the Rainbow Reel’s colour while that reel is active. Rainbow Reels are activated when a cloud symbol lands on the reel.
Multiplier Clouds
When a cloud lands on one of the reels, you’ll see a multiplier value appear which is then added to the Reel’s Multiplier.
Normal Clouds
If the Reel Multiplier is not already activated, a normal cloud landing on the reels will activate it. It will then add one of the following values to the Reel Multiplier – 2x, 3x, 4x, 5x, 10x, 25x, 50x, 100x, 250x.
Double Rainbow Clouds
This works in a similar way to the normal cloud in the Double Rainbow slot. The same multiplier values can be added to all active Reel Multilpiers, and it also awards 3 extra spins where all activated Rainbow Reels remain active, so 2 more than a normal cloud.
Full Rainbow feature
When you managed to activate all Rainbow Reels simultaneously, the Full Rainbow feature is triggered. When this happens, all Reel Multipliers are multiplied by 1 of the following values:
- 2x
- 3x
- 4x
- 5x
- 10x
You also get 5 extra spins where all activated Rainbow Reels remain active, which could potentially lead to big payouts.
Buy Bonus feature
For 10 x your stake, you will get 1 Rainbow Spin which guarantees a minimum of 1 extra spin with 3 activated Rainbow Reels with Reel Multipliers starting at 4x. For 50 x your stake, it’s almost exactly the same but you will get 4 extra spins instead of 1. Please note, however, that this buy bonus option is not available in the UK.
Double Rainbow Review Summary – Not one of Hacksaw’s best
The Double Rainbow slot game has a lot going on in terms of bonus features, the multipliers and extra spins that come with it. This part we like and there’s the potential to win big, especially being a slot that’s not super high in terms of volatility. But that’s where the enjoyment ends for me. I’m not a fan of the theme but that’s not to say many won’t like it. It is pretty niche though.
Overall, it’s a well-designed slot and the audio is quite nice, but it’s only going to appeal to a certain type of player in my opinion. There are better slots from Hacksaw Gaming, to be honest, that also come with bigger max win potential, so consider some of those if this doesn’t float your boat.
But if rainbows are your thing and you want to try some alternatives, consider Barcrest’s Rainbow Riches Power mix slot that comes with some great bonus features and max wins of 12,500 x your stake. Another one to try is 1x2gaming’s Super Rainbow Megaways slot that has up to 200,604 ways to win and an impressive max win potential of 35,000 x your stake.
Double Rainbow FAQs
The Double Rainbow return to player rate is a healthy 96.38%. This is well above average and what’s even better is that the hit frequency is at 39.49%, which is very generous.
The maximum win is 5,000 x your stake, which is lower than the usual 10,000 x seen in most Hacksaw titles, but still isn’t too bad. Your best chance of hitting the top prize will come in the bonus features due to the multipliers and the potential for a full rainbow.
No, there are no free spins on offer but extra spins can be had with the $1 and multiplier clouds. We explain how it all works in our review.
Yes, the $1 at Online-Slot.co.uk. It’s all about clouds and rainbows. Enjoy it on mobiles, tablets, PC or laptop devices. We have over 4,000 slot demos overall to choose from and play.
