Free spins in Double Rainbow activate upon three or more clouds of any variety, carrying over all established reel multipliers into a bonus phase where cascades persist, retriggers add one spin for Normal Clouds or three for Double variants, and compounded boosts often spiral payouts far beyond base game norms. The game's marquee Full Rainbow feature explodes into action exclusively when all seven reels simultaneously host multipliers, at that moment globally enhancing every individual reel multiplier by a random 2x, 3x, 4x, 5x, or 10x factor—potentially forging totals in the thousands—and bestowing five extra spins with perpetual full-reel activation to maximize cluster opportunities under this supercharged regime. Bonus buy avenues streamline access: a 10x bet investment guarantees one Rainbow spin replete with cloud activations and multipliers, while 50x secures four such enriched spins, providing RTP-efficient jumps ideal for time-conscious players seeking immediate depth. Payouts for clusters progress from 0.1x the stake for minimal five-symbol groups to an impressive 50x for sprawling 15-plus symbol monsters, ensuring cascades yield incremental gains even sans multipliers, with the line-free grid permitting wins to morph organically across vast areas for unpredictable yet rewarding sprawl.
