Double Rainbow: Slot Overview

Anyone who remembers the infamous Double Rainbow YouTube clip will know just how giddy a real-life double rainbow can make people feel. The video was such a mood-lifter that it even landed at number 9 on The Ringer’s Happiest Day on the Internet this Decade list. Fast-forward a few years and Double Rainbow is now the title of a fresh slot in Hacksaw Gaming’s Pocketz Series. And while Hacksaw Gaming has already proven they can deliver seriously cute games, they’ve gone even further with Double Rainbow—so far, in fact, that it can spark mixed reactions. To figure out where you stand, let’s dive in.

For starters, Double Rainbow doesn’t do “subtle,” and it hits the screen like a glitter cannon going off. Sitting on a cushion of clouds is a 7-column, 6-row grid framed by soft pastel skies, a rainbow-maned unicorn, rainbows, and sweet-like reel symbols. It’s either wonderfully fabulous or an overload of cuteness that edges into babyish territory—players can decide for themselves.

The math model is far less delicate, although a 3 out of 5 volatility rating means it isn’t among Hacksaw’s most brutal titles either. RTP can differ a lot depending on jurisdiction, ranging from 96.38% down to 88.38%, so it’s smart to check before you start spinning. With two bonus buy options available, RTP also shifts when they’re used—rising to 96.41% for buy option one and dipping to 96.27% for buy option 2. Standard bets run from 10 p/c to $/€100, and the game is playable on any device.

Double Rainbow runs on a cluster pays mechanic, which triggers cascades whenever winning clusters land. A winning cluster is formed when at least five matching symbols connect horizontally or vertically. Seven candy-style items replace traditional pay symbols, and each carries the same value. A five-symbol cluster pays 0.1x the bet, climbing to 50x the bet for clusters of 15+ symbols.

Double Rainbow: Slot Features

Just like a rainbow has seven main colours, Double Rainbow features 7 Rainbow Reels. When a Cloud symbol lands, it activates its reel by assigning it a Reel Multiplier. Reel Multipliers appear in one of the seven symbol colours. If a reel already holds a multiplier, the incoming value is added on top. Reel Multipliers apply to any winning cluster that matches the multiplier’s colour.

Multiplier Clouds

In Double Rainbow, there are 2 types of cloud symbols. Normal clouds add multipliers of x2, x3, x4, x5, x10, x15, x25, x50, x100, or x250 to their reel. Normal Clouds also award +1 extra spin where all activated reels remain active. The other type is Double Rainbow Clouds. These also add x2, x3, x4, x5, x10, x15, x25, x50, x100, or x250 multipliers to their reel, but they award +3 extra spins where all activated reels remain active. Extra spins are free.

Full Rainbow

Activate all 7 reels and you’ll trigger the Full Rainbow feature. When it hits, all seven reel multipliers are multiplied by x2, x3, x4, x5, or x10. On top of that, you also receive +5 additional spins where all activated reels remain active.

Bonus Buy

If this option is available, players can pick from two buy bonus options. The first is 1 Rainbow Spin, which guarantees at least 1 extra spin with three activated reels with Reel Multipliers starting at x4. This costs 10x the bet. The second costs 50x the bet and guarantees at least 4 extra spins with three activated reels with Reel Multipliers starting at x4.

Double Rainbow: Slot Verdict

Picture yourself strolling through a toy store, slipping, and landing face-first into a My Little Pony display—then you’re pretty close to the Double Rainbow vibe. Is it too childish? Plenty of players will likely say yes, and it’s not always easy to argue. Candy-themed slots are everywhere right now, but Double Rainbow pushes the concept even further. The Pocketz Series is built around handheld, Candy Crush-style play, yet Double Rainbow can feel a bit uncomfortably juvenile at times. Nolimit City may dominate the edgy, shock-value corner of the market, but Double Rainbow delivers its own kind of shock from the opposite direction.

That said, since the presentation is about as divisive as it gets, it’s worth setting it aside and looking at how the game plays. On that front, Double Rainbow is classic Hacksaw again, using a straightforward but clever feature set that can both bait and reward as smoothly as anything else in the Pocketz Series. A particularly welcome detail is that wins don’t need to land on the same reel as the multiplier. For instance, if you’ve got a red multiplier sitting at the top, any red symbol win anywhere on the grid will be enhanced. Multipliers can stack quickly too, and for reference, the highest value we saw during testing was x259.

Still, it’s fairly common to build up a respectable multiplier and then fail to connect a cluster in the matching colour. That’s part of the volatile character of Hacksaw games, and lately there’s also been a slight tendency to pair them with potentially punishing bonus buys. Harvest Wilds raised the stakes in that area, and Double Rainbow tries hard to keep pace—bought Rainbow Spins are very much luck-of-the-draw, just as capable of producing dead spins as they are of erupting into a tinsel-filled blowout. If everything lines up at the end of this rainbow, the metaphorical pot of gold can be worth 5,000 times their stake.

Double Rainbow offers plenty of tempting flashes thanks to its potentially huge multipliers, and anyone who can’t get enough sweetness and adorableness should be delighted. For everyone else, it may be tougher to look past the relentlessly cute theme—though to be fair, switching your phone to portrait mode makes the game feel a lot less fluffy.
