The bonus round occurred nine times across those 1,200 spins, giving an observed frequency of about once per 133 spins, almost matching the advertised rate. The single largest free spins payout I noted was 211x my bet, while the average bonus round return stood at 45x. I also landed a 210x win in the base game when a perfectly timed Kong Multiplier landed on a screen full of mask symbols. My calculations suggested a volatility index in the medium-high range, which corresponds to a potential maximum win I’ve seen stated as 5,000x the stake. For anyone who likes dramatic swings and the occasional monster roar that turns around the session, this math profile delivers exactly that.
