The Green Knight series: Play'n Go's escalating medieval bonus
The Green Knight series is Play'n Go's high-volatility medieval franchise, built on sticky wilds, free spins and multipliers across a 5x3, 20-payline frame. Both Green Knight slots use the armored figure as the feature anchor, with the sequel extending the bonus progression instead of replacing the original reel structure.
