Hacksaw Gaming’s candy-colored unicorn ride: Double Rainbow Description

Step onto a cloud and look across a sky streaked with vibrant arcs: that’s the feeling Double Rainbow goes for from the first spin. A cheeky unicorn stands guard by a pastel 7x6 grid peppered with jewel-like candies, while rainbow hues tint each reel with its own identity. Under the sweetness, though, sits a clever color-driven system that gives every cluster win a chance to be supercharged. Developed by Hacksaw Gaming, Double Rainbow is a Video Slot released on 2022-03-09 built around a 7 reels x 6 rows grid and the Cluster Pays engine. There are no traditional paylines here; instead, wins form via groups of adjacent matching symbols. Every win triggers cascades to keep the action flowing, and the signature mechanic assigns color-specific Reel Multipliers to reels, which then boost clusters of the corresponding color. On the numbers side, Double Rainbow runs on medium volatility with a maximum win of x5,000. The game supports RTP ranges; configurations include 96.38%, 94.53%, 92.45%, and 88.38%. Betting is flexible, from a minimum of €0.10 to a maximum of €100 per spin, fitting short test sessions and longer play equally well in demo mode. Feature-wise, clouds drift in to attach multipliers to reels, grant extra spins, and, when things align just right, ignite the Full Rainbow for a global multiplier boost. There’s also a Bonus Buy menu with two flavors of Rainbow Spins for those who want to jump straight into the colorful core mechanics. The result is a sugar-sweet wrapper around a surprisingly tactical color-matching system that can escalate quickly when clouds start cooperating.

Design and Atmosphere

A sugar-sprinkled fantasy sets the tone: soft clouds, a rainbow bridge arching behind the grid, and a friendly unicorn with a flowing, multicolored mane keeping watch on the left. The palette leans into playful pastels and glossy highlights, making each candy symbol pop like polished gems. Lighting stays bright and cheerful, with gentle gradients across the background and subtle motion that makes the sky feel alive. It’s unmistakably whimsical and purposefully “light side” in its art direction, echoing toy-box aesthetics while keeping the interface clean and readable during cascades and feature bursts.

Symbols

  • Red Candy — 5 to 15+ = 0.1x to 50x

Sound Effects and Soundtrack

A buoyant, piano-led soundtrack sets a cheerful tempo—bouncy beats with a cartoon-like vibe that complements the pastel visuals. Spin sounds are soft and clicky, while wins and feature activations add brighter chimes and twinkles for that “sugar rush” feel. It’s crisp, upbeat audio that keeps momentum without overpowering the screen action.

Features and Bonuses powered by color-coded multipliers and free extra spins

Cluster Pays with Cascading Wins

Wins land when 5+ matching symbols connect horizontally and/or vertically. After each win, the cluster is removed and new symbols cascade into place. Consecutive wins in a single spin can chain together like fireworks when the right colors line up.

Rainbow Reels and color-specific Reel Multipliers

Each of the seven reels embodies a rainbow color and can hold a Reel Multiplier. When active, that reel’s multiplier applies exclusively to winning clusters of the same color. This is the heart of Double Rainbow: stacking value on specific colors turns ordinary clusters into thrilling spikes. Multipliers can stack on a reel over time, and their activation/maintenance is managed by cloud symbols and the extra spins they award.

Multiplier Clouds: x2 to x250 with +1 extra spin

Landing a Normal Cloud on a reel does two things: - It activates that reel’s multiplier (if it wasn’t active already). - It adds a random value of x2, x3, x4, x5, x10, x15, x25, x50, x100, or x250 to that reel’s multiplier. You also receive +1 extra spin, and all activated Rainbow Reels remain active during those extra spins. Each cloud also assigns a color to the reel multiplier, aligning with one of the seven candy colors, so only matching-color cluster wins get boosted. New clouds add their value on top of existing multipliers, which can create nail-biting builds across multiple reels.

Double Rainbow Cloud: global boost with +3 extra spins

The Double Rainbow Cloud comes with the same multiplier range (x2 to x250) but distributes that value to all active Reel Multipliers. It also awards +3 extra spins, keeping all activated Rainbow Reels alive while you hunt for matches in the boosted colors. It’s the feature that can turbocharge a board already primed with reel multipliers.

Full Rainbow: multiplier boost for every active reel +5 extra spins

Trigger Full Rainbow by activating all seven Rainbow Reels simultaneously. When this happens: - Every existing Reel Multiplier is boosted by an extra x2, x3, x4, x5, or x10. - You receive +5 extra spins, and all activated Rainbow Reels remain active. It’s the crescendo of the system—reach it, and the entire grid glows with potential for any color match that ties into your charged reels.

Bonus Buy: two Rainbow Spin options

For instant access to the rainbow engine, the Bonus Buy offers: - 1 Rainbow Spin (cost: 10x bet) — guarantees at least +1 extra spin with 3 active Reel Multipliers starting at x4. - 4 Rainbow Spins (cost: 50x bet) — guarantees at least +4 extra spins, again with 3 active Reel Multipliers starting at x4. These options shortcut straight to the game’s core loop, where colors, multipliers, and cascades interact at full tilt.

Statistics and Math for number-minded players

RTP

RTP ranges are supported. Available configurations include 96.38%, 94.53%, 92.45%, and 88.38%. The top configuration sits a touch above the industry’s common reference point, while lower settings do exist as part of the range. Over longer demo sessions, higher RTP configurations typically stretch the playtime and show more of the feature set.

Volatility

Double Rainbow runs on medium volatility. Expect a balanced rhythm: steady clusters from the cascade engine punctuated by spikes whenever reel multipliers align with the right colors. It’s tuned for variety rather than extreme drought-or-downpour swings.

Paylines and Win Mechanics

There are no paylines; it’s a Cluster Pays grid with 7 reels x 6 rows. Wins require 5+ adjacent identical symbols (horizontal and/or vertical), followed by cascades that can chain multiple wins from a single spin. The interplay with color-locked Reel Multipliers is the defining twist.

Bet Limits and Accessibility

Stakes range from a minimum bet of €0.10 to a maximum bet of €100 per spin. The wide spread makes it easy to explore the mechanics at a comfortable pace in demo mode, then scale up or down as you please.

Conclusion

Double Rainbow is a sweet shop for the eyes and a puzzle box for the brain. The standout is the color-specific Reel Multiplier system: clouds wake up reels, multipliers stack, and wins pop only when symbol colors match their activated reel. That constraint turns simple clusters into little tactical moments—do you have enough green on an active green reel? Can a cascade drop red clusters onto a charged red reel? When the Double Rainbow Cloud sprinkles its value across all active reels or you hit the Full Rainbow and every multiplier gets a global boost, the tension ramps up beautifully. Strengths: - Cluster Pays with cascading wins on a 7x6 grid keeps the screen busy and the pace brisk. - Reel Multipliers (x2 to x250) tied to symbol colors feel fresh and rewarding when aligned. - Extra spins from clouds and the +5 spins in Full Rainbow extend hot sequences without a traditional free-spin round. - Bonus Buy lets you dive straight into the multipliers with pre-activated reels. Potential drawbacks: - The ultra-cute presentation won’t be everyone’s cup of tea. - RTP ranges exist, so configurations vary. - The x5,000 max win is solid but not record-chasing by Hacksaw standards. Who will love it? Fans of candy-world aesthetics, grid slots, and mechanics that reward planning around color matching. If you enjoy watching multipliers snowball through cascades, this one shines. For similar vibes and mechanics, try: - Tasty Treats (Hacksaw) — cluster pays on a 6x5 grid with floating Bubble Boosters for wilds/multipliers and potential up to x10,000. Sweeter and a touch more explosive in the top end. - King Carrot (Hacksaw) — a 7x7 cluster pays playground focused on symbol transformations and epic versions with up to x100 multipliers, also capped at x10,000. - Fluffy Favourites (Eyecon) — a cutesy classic with free spins and a x5,000 ceiling; different feature suite, similar soft-toned charm. There’s also a Megaways variant if you want a modernized twist. In short, Double Rainbow pairs a playful façade with a smart, color-locked multiplier engine. When the clouds roll in and the reels light up, it’s hard not to smile.
