What Is Double Rainbow?

Double Rainbow takes players up among purple skies, fluffy clouds and rainbow-maned unicorns, offering a deliberate splash of light relief within Hacksaw Gaming's often edgier catalog. Following hot on the heels of the considerably grimmer The Bowery Boys, the contrast is stark — and reviewers have noted this stands as something of a marmite release, with its cutesy presentation either a welcome getaway or a bit too childish depending on taste.

The grid runs on a 7-reel, 6-row layout using cluster pays: 5 or more matching symbols connecting horizontally or vertically form a win, with cascading reels clearing successful clusters to make room for new symbols and potentially chain further hits.

Rainbow Reels and Multiplier Clouds

Each of the seven reels ties to its own rainbow color, and the corresponding section of the game's logo sparkles whenever that specific reel carries an active multiplier — a nice visual touch that makes tracking which reels are currently boosted genuinely intuitive. Multiplier Clouds drive the value: Normal Clouds and the rarer Double Rainbow Cloud both add multiplier value to their reel, and the Full Rainbow feature represents the game's biggest moment, activating when enough reels carry active multipliers simultaneously.

Two Bonus Buy Options

Rather than a single fixed bonus buy price, Double Rainbow offers two distinct purchase options with genuinely different risk profiles: Buy Option 1 increases the effective RTP to 96.41%, while Buy Option 2 lowers it slightly to 96.27% — giving players a real, transparent choice depending on how they'd rather balance cost against expected return. A standard Wild symbol substitutes for all other symbols to help complete cluster combinations throughout regular play.

RTP, Volatility and the Realistic Odds

Default RTP is 96.38%, with 94.53%, 92.45% and 88.38% configurations also available depending on the operator — worth verifying before real-money play given the meaningfully wide spread. Volatility is rated medium, and hit frequency of 39% is genuinely generous, meaning wins land considerably more often than most of Hacksaw's extreme-volatility catalog, even if the eye-catching moments are correspondingly saved for the Full Rainbow feature.

The 5,000x max win comes through stacked Multiplier Cloud values compounding during an active Full Rainbow sequence. When the cap is reached, the current round ends immediately and the full winnings are awarded outright. Bets run $0.10 to $100 per spin.

Our Verdict

Double Rainbow succeeds as exactly the kind of deliberate change of pace Hacksaw seems to have intended — the 39% hit frequency delivers a noticeably steadier, more forgiving session than the studio's usual extreme-volatility formula, and the reel-specific rainbow coloring gives the Multiplier Cloud system a genuinely intuitive visual language. The 5,000x ceiling and whimsical unicorn theme won't satisfy players chasing Hacksaw's biggest headline numbers or darkest atmospheres, but as a lighter, more approachable release with real mechanical charm underneath its cutesy surface, it holds up well.
