The Sword and the Grail Excalibur: Slot Overview
The Sword and the Grail Excalibur is a 5x3 video slot from Play'n GO with 20 fixed paylines, a 96.2% RTP, high volatility, and a 25,000x max win. I see it as a direct extension of the earlier game, keeping the Grail wild multipliers up to x100 while adding King's Prizes and roaming wild behaviour in free spins.
From a math perspective, the numbers tell you this is a top-heavy model. Base symbol values are modest, the feature buy is absent, and several reviewers flagged long stretches before the bonus appears. The free spins round is where the profile shifts, because the Sword Meter progression and wandering wilds are the main route to meaningful returns.
Symbols & Payouts
5 reels, 3 rows, 20 paylines, standard left-to-right line pays. Looking at the paytable structure, low symbols T to A return 1x to 2x for five of a kind, while the premium set, Lancelot, Merlin, Guinevere, and King Arthur, pays 5x to 15x. That is not a rich base table, so the multiplier layer matters more than the raw symbol values.
Grail Wilds substitute for all regular symbols but not the scatter or instant prize symbol. In ordinary form, the wild pays on the same level as the top symbol, but if it carries the Sword Meter multiplier, five wilds can climb to 1,500x when x100 is active. King's Prizes are separate instant awards, with values reported at x1, x2, x3, x5, or x10 of stake.

The Sword and the Grail Excalibur: Slot Features
Sword Meter is the central mechanic. Positioned above the reels, it can turn a Grail Wild into a multiplier wild and apply x2, x5, x10, or x100 to a line win. The same meter also boosts King's Prizes when active, which gives the base game a second route to value outside regular line hits.
3 or more Sword scatters trigger Free Spins. Before the round starts, a Round Table Wheel awards one of six starting packages, 8 spins with 3 or 4 scatters, 10 spins with 2 or 3 scatters, or 12 spins with 0 or 1 scatter. Extra triggering scatters are added to the Sword Meter when the bonus begins.
During free spins, every 5 collected Sword scatters unlocks the next multiplier stage and adds 3 more spins. Grail Wilds become semi-sticky and wander across the reels until they move off. That movement cuts both ways. I like the extra board coverage, but not everyone will enjoy wilds leaving before the round ends.

The Sword and the Grail Excalibur Slot RTP & Volatility
96.2% RTP is solid on paper, though lower settings also exist at 94.2%, 91.2%, 87.2%, and 84.2%. Volatility is high to very high across the source reviews, and one review quotes the chance of landing the full 25,000x at less than 1 in 1 billion. From a math perspective, that confirms a heavily right-skewed payout curve.
Betting runs from 0.10 to 100 per spin, which suits both casual and high-stakes play, but the game is not bankroll-friendly in practice. The base game can drag a bit, hit frequency is not stated, and scatter arrival was described as unimpressive in testing. Without a Bonus Buy, bonus EV has to be accessed through natural triggers only.
