Double Rainbow Slot Overview

Double Rainbow is a 7 reel 6 row cluster slot from Hacksaw Gaming, packed with bright candy colours and a syrupy unicorn vibe. I felt like I had stepped into a cartoon cloudscape, with rainbows arcing behind the grid and a cute unicorn watching every spin. Under all that sweetness sits a fairly serious math model, where clusters of 5 or more matching symbols drive the whole experience.

From my first session, Double Rainbow came across as the softer sibling of Hacksaw's darker titles, though the volatility still keeps you awake. The grid format, colour based multipliers and cascading wins mean the game feels busy without being confusing. It all revolves around building up reel multipliers through cloud symbols, then hoping the right coloured clusters land while everything is active for those satisfying rainbow hits.

Double Rainbow Slot Information

Double Rainbow plays on a 7 by 6 layout where clusters connect horizontally or vertically, so lines do not matter at all. Any win removes the candies and new symbols tumble in, which can chain several hits from one paid spin. The base game rhythm is very much about these cascades, with the background music and soft sound effects adding to the dreamy, almost saccharine feel.

I mainly played Double Rainbow on mobile, where the Pocketz set up works nicely in portrait mode. Buttons sit close to the reels, the paytable is easy to open, and the whole interface feels tailored for thumb play. On desktop the slot spreads out a bit more, yet the visuals retain that bright cartoon charm, so you are still looking at the same playful but slightly overwhelming rainbow world.

Double Rainbow Symbols And Paytable

Symbols in Double Rainbow are simple candies in seven colours, from red and orange through yellow, green and blue to pink and purple. Every colour pays the same, which makes cluster counting easy when the grid fills up. Hit 5 of any candy and you get 0.1 times your bet, while 15 or more matching symbols in one cluster award 50 times, regardless of which sweet icon did the work.

The wild symbol is a lightning bolt marked WILD, and it substitutes for all paying candies to help extend or complete a cluster, though it has no value on its own. What really defines Double Rainbow for me is how those clouds tie the colours on the reels to specific multipliers, so once a reel has its coloured value active, you start rooting for that particular shade to flood the grid.

Double Rainbow Slot Features

Feature wise, Double Rainbow leans heavily on its Rainbow Reels mechanic. Each of the seven reels has a colour and a reel multiplier that can apply to wins formed with candies of that colour. Land a normal cloud and you reveal a value between 2x and 250x, which is added to that reel's multiplier. You also gain one extra spin where any activated Rainbow Reels stay live instead of resetting straight away.

Sometimes a Double Rainbow Cloud drops in, and that is where things start to escalate. Whatever multiplier sits on that reel is added to every other active reel multiplier, again with values ranging from 2x up to 250x. You receive three extra spins, during which all those coloured reels remain active. When this lines up with big clusters of matching candies, the screen can fill with raised wins in a hurry.

The peak of Double Rainbow arrives with the Full Rainbow feature, triggered when all seven Rainbow Reels are active at once. At that point a random value between 2x and 10x multiplies every reel multiplier, and you collect five extra spins while they stay active. Outside the UK you can shortcut the grind via the bonus buy options at 10x or 50x bet, both starting you off with three coloured reels and 4x multipliers.

Double Rainbow RTP, Volatility, And Max Win

From a numbers angle I found Double Rainbow fairly balanced for a Hacksaw title. The default RTP sits at 96.38 percent, though casinos can offer lower settings such as 94.53, 92.45 or even 88.38, so I always check the info panel. Volatility is rated medium, which matches my sessions where dry spells did appear but never felt brutal, and the maximum win is capped at 5000 times stake.

Double Rainbow Slot Conclusion

After plenty of spins, Double Rainbow left me torn between its sugary surface and sharp feature set. The pony and candy styling is almost painfully cute, yet the Rainbow Reels and cloud multipliers offer proper gambling moments when they line up. If you can tolerate the childlike art, there is a solid medium volatility slot underneath, capable of throwing colourful cascades and the odd 5000x dream across the screen.
