Double Rainbow, from Hacksaw Gaming, uses a 6-7 layout and presents rainbow- and sky-themed visuals with unicorns, white accents, stars, and sky motifs.

Core mechanics include Wild symbols that substitute across reels, Multipliers that can apply to wins, and Cascading symbol removal that clears winning combinations before new symbols drop in, supplemented by Additional Free Spins, Respins, and a Buy Feature option. The RTP is 95% and volatility is described as Medium, indicating mid-range risk and return. Bet ranges run from Min USD 0.2 up to Max USD 100, enabling low-stake play and higher-stake rounds. The top win is x11 and the hit frequency is 39, reflecting a relatively frequent but modest payout cadence. Pacing and risk are moderated by cascading play and feature-trigger randomness, offering variable play sessions.

Overall, the presentation aligns a vivid visual theme with layered mechanics to yield a steady, calculation-driven slot experience. The visuals emphasize sky and rainbow motifs while keeping the focus on symbol interactions rather than narrative elements.
