Double Rainbow (Hacksaw Gaming) – Review & Demo Play

Double Rainbow Slot Theme And Storyline

I loaded Double Rainbow and the first thing that hit me was a shotgun blast of glitter. The 7x6 grid sits on a bed of clouds, wrapped in pastel hues, a rainbow-maned unicorn on standby, and reels packed with candy-like symbols. It’s either fabulous or babyish, and I’ve seen players split down the middle. I’ve played enough Pocketz titles to know Hacksaw can do cute, but this one leans hard into it, and the presentation is as polarising as it gets.

On the practical side, Double Rainbow is built for phones. In portrait mode the game looks less fluffy and the grid breathes. That helps me focus on the core loop rather than the sugar rush. The whole thing feels snackable, which suits the cluster action. I bounce between quick sessions and longer runs without feeling lost, and the UI makes sense straight away. If the candy shop vibe is not for you, portrait view tones it down nicely.

Double Rainbow RTP, Volatility, And Max Win

Double Rainbow runs a 3 out of 5 volatility profile with a top RTP of 96.38%, though operators can set 94.53%, 92.45% or even 88.38% depending on market. Stakes range from 0.10 to 100 per spin. Max win caps at 5,000x, which is fair for a Pocketz release. Non-UK players get bonus buys, shifting RTP slightly to 96.41% or 96.27% based on the option taken. I always check the in-game info panel in cash play to see which setting is live.

Double Rainbow Rules And Gameplay

This is a 7x6 cluster pays slot, and wins land when five or more matching symbols connect horizontally or vertically. Winning symbols vanish and cascades drop new ones into place, letting sequences chain together. The entry level five-symbol cluster pays 0.1x, while groups of 15+ pay 50x. Bets are light at the bottom end and flexible up to 100, so I can toggle stakes to suit the session. The rhythm is quick and the grid stays busy.

A Wild symbol helps out by substituting for any pay symbol, but it has no value of its own. The real spark comes from the Rainbow Reels concept. Each of the seven reels carries a colour, and Cloud symbols can activate a reel multiplier tied to that colour. If a reel already holds a value, new clouds add on top. Those colour multipliers apply to matching cluster wins, and they stick around during any extra spins you land.

Symbols And Paytable in Double Rainbow

Paying symbols are candies in red, orange, yellow, green, blue, pink and purple, and every colour pays the same. Hit five in a cluster for 0.1x, scale that up to 50x for 15+ in view. It keeps the focus on building groups rather than chasing a premium. The Wild, a lightning bolt with WILD on it, substitutes for any pay symbol to help complete clusters, but it carries no direct payout on its own in the paytable.

Double Rainbow Bonuses And Special Features

There are seven Rainbow Reels in Double Rainbow, and a Cloud symbol can activate its reel by adding a reel multiplier in one of the seven colours. If that reel is already active, the new value is added to the existing tally. The key bit I like is that colour wins do not need to land on the same reel as the multiplier. A red multiplier at the top will still apply to a red cluster anywhere on the grid.

You'll see two types of Cloud symbols. Normal Clouds add multipliers of x2, x3, x4, x5, x10, x15, x25, x50, x100 or x250 to their reel and grant +1 extra spin. Double Rainbow Clouds come with the same multiplier range, and they award +3 extra spins. During these extra spins, all activated reels remain active, and any fresh Cloud that lands simply stacks on the current reel value. It can build fast when the grid cooperates.

Trigger all seven reels at once and the Full Rainbow feature kicks in. Every active reel multiplier is multiplied by x2, x3, x4, x5 or x10, and you also get +5 additional spins with everything still active. If you're eligible for Bonus Buy (not UK), there are two choices: 1 Rainbow Spin for 10x, or 4 guaranteed extra spins for 50x. Both start with three activated reels and reel multipliers from x4, which helps set the board.

Review Summary And Verdict for Double Rainbow

Strip away the candy coating and Double Rainbow plays like textbook Hacksaw. Simple but smart, the colour multipliers tease and reward in waves, and they can rack up quickly when clouds land in clusters. I rate the way wins benefit from a colour anywhere on the grid, as it keeps momentum even when reels aren't lined up. During testing I've watched the tally climb to silly levels, and that chase is what kept me locked in.

It's not all sweetness. You can tee up a decent reel value and then whiff on the matching colour for ages. That ebb and flow fits the medium profile, but runs can still sting. Bought Rainbow Spins are luck of the draw as well, as likely to fizzle as they are to shower tinsel. When it lands, the game can pay, and at the far end sits a pot of gold worth 5,000x stake.

Theme wise, I sit somewhere in the middle. Some will love the adorableness, others will find it too kiddy, and I get both takes. I tend to flip my phone to portrait and let the features do the talking. If you want a pocket slot with colour-based multipliers, cascading wins and a fair 5,000x ceiling, Double Rainbow does the job, and it's handy when I fancy a quick cluster session on mobile.
