Mick’s Verdict:
I’d never really given this slot a proper chance in the past, always assumed it was just another tumble‑grid filler. Turns out I’ve been missing out. The first 100 spins were cracking — a bonus that actually paid and chunky base hits of 108x, and 62x. After a start like that, I fully expected the next 150 spins to die on its arse, but it didn’t. It kept on giving. Two more bonuses landed, and each time I chose the High Volatility Multiplier Free Spins, which delivered again 78x and 60x. A lively, enjoyable session from start to finish. Recommended.
