The Sword and the Grail series
The Sword and the Grail's collection formula
Within Arthurian slots, Play'n Go's The Sword and the Grail series occupies a specific niche: high-volatility play centered on symbol collection, free spins and multipliers. The Sword and the Grail established that formula in 2019 on a 5x3, 20-payline frame, combining an energy collection system with wilds, scatters and a 10,000x maximum win.

The Sword and the Grail Excalibur retains the same grid, payline count, bet range and high-volatility profile, then expands the reward machinery. Wild multipliers, random multipliers, extra free spins and a prize wheel lift the maximum win to 25,000x. The sequel's RTP is slightly lower at 94.2% versus 94.5%, making its larger ceiling and more variable bonus modifiers the substantive upgrade.
