Rather than building a new title from the ground up, the release uses Big Bass Splash 1000 as its base. The franchise’s signature Money symbol collection mechanic stays intact while a seasonal skin gets swapped in.
The headline mechanical difference is a shift in risk profile. This variant runs on a 5×3 grid with 10 paylines at an RTP of 96.50%, and the volatility has been eased to medium against the high-variance base game. That softens the swings while keeping the same top-end potential.
That ceiling stays substantial at 20,000x the bet. It’s reserved for a fully developed free spins round where Fisherman Wilds collect Money symbol values and progressive retriggers push collection multipliers higher.
How to play Rainbow Gold
Before joining the Ministry of Finance, Fabio Macorin served in Brazil’s Federal Police for 17 years. For a decade, he focused specifically on the investigation and prevention of banking and financial fraud. This experience helped shape his approach to betting regulation, particularly regarding anti-money laundering, financial monitoring, combatting the illegal market and inter-agency cooperation.
Brazil’s regulated betting market formally launched in 2025 and has since become one of the most closely watched regulatory initiatives in the global gaming and betting sector. Macorin, who also served as the SPA’s undersecretary for monitoring and enforcement, has been directly involved in initiatives to combat illegal operators, strengthen cooperation with financial institutions, telecommunications providers and other government authorities, as well as develop data-driven tools for regulatory oversight and enforcement.
Commenting on his election, Macorin expressed his honour at joining the IAGR board and contributing Brazil’s experience to the association’s international work.
