Double Rainbow

Double Rainbow from Hacksaw Gaming is a 7x6 cluster-pays slot with a rainbow-chasing theme built around Rainbow Reels, cascading wins, and wild substitutions. RTP sits at 96.38% in the main version, with lower-rtp variants out there, and the max win is a juicy 5,000x. Volatility is medium, but don’t let that fool you — the bonus round is where the real sweat starts. Cloud Multipliers can climb up to x250, and Full Rainbow Respins with a built-in x2 across all reels can hit hard. The Bonus Buy for Rainbow Spins or Double Rainbow Spins is there if you want to skip the grind, but that’s also where bankrolls can get chewed up fast. You’re basically paying for a shot at a monster combo, and sometimes it lands, sometimes it stings. If you’re brave enough and your bankroll can take the swings, this one’s worth a spin.
