Advanced stealth method discovered by the GTA6Copilot team. Zero wanted stars, maximum payout.
This GTA 6 Underground Casino money method takes advantage of a hidden basement route beneath the Diamond Casino, letting you clear the vault entirely undetected. Because the entire run can be completed without alerting a single guard, your wanted level stays at zero stars from start to finish.
Access the underground route through a maintenance tunnel connected to a nearby parking structure, avoiding the casino’s main security checkpoints entirely. Moving slowly between the tunnel’s patrol rotations is key to keeping the entire job stealthy, since triggering even one alarm forces a much harder fallback plan.
This zero-star approach nets roughly $4.8 million per completed run and can be repeated after a cooldown period, making it one of the safest high-value money methods in the game for players who prefer avoiding police entirely.
