Double Rainbow is Hacksaw Gaming’s candy-colored departure from its usual gritty theming, set in a whimsical sky of pastel clouds and rainbows guided by a unicorn with a flowing rainbow mane. Released in 2022, it runs on an unusually large 7-reel, 6-row cluster-pays grid, carries a top-tier RTP of 96.38%, and sits at medium volatility with a comparatively modest 5,000x max win ceiling next to Hacksaw’s typical 10,000x-plus releases.
Double Rainbow isn’t available at either of our linked casinos — both are RTG-powered, and Hacksaw Gaming doesn’t license its games to RTG-style operators. Try Sloto Cash instead for a working real-money slots option, or play Double Rainbow in demo mode at Hacksaw Gaming’s own site.

The 7×6 cluster grid is larger than almost anything else in Hacksaw’s catalog, giving Double Rainbow more surface area for clusters of matching candy symbols to form. Wins tumble away and new symbols drop in, and the game’s Rainbow Reels mechanic periodically transforms sections of the board, adding a visual signature that sets it apart from the studio’s more conventional cluster-pays titles like Hand of Anubis.
Multiplier Clouds sit above the reels and grow through three stages — Normal Cloud, Double Rainbow Cloud, and Full Rainbow — each adding to the tumbling multiplier that can climb as high as 250x across a single sequence of cascades. Free spins add dynamic reel multipliers on top of the base cascade mechanic, and a Bonus Buy option is available for players who want direct access to the feature rather than relying on natural triggers.
