About Double Rainbow

Double Rainbow (June 2024) explores the rainbow/Irish luck theme at Hacksaw Gaming. The structure: a 7x6 cluster pays grid (5+ matching adjacent symbols form a win), stakes from €0.10 to €100. Top-tier RTP of 96.38% — above the Hacksaw average of 96.20%. Hacksaw offers two Bonus Buy modes: Buy 1 (RTP boosted to 96.41%) and Buy 2 (RTP drops to 96.27% — unusual for Hacksaw, where the bonus buy usually boosts the RTP). Degraded versions can drop as low as 88.38% depending on the casino. Medium volatility — accessible.

The signature mechanic is Rainbow Spins. Cloud symbols can trigger this special mode, which unlocks boosted multipliers applied to the following cluster wins. Classic cascading wins: winning symbols disappear and new ones drop in. Max win of 5,000x is light next to Hacksaw flagships (Wanted 12,500x, Bullets and Bounty 20,000x) but is consistent with the medium volatility.
