The Sword and The Grail Slot Overview
The Sword and The Grail is a 5-reel, 3-row slot from Play'n GO running on 20 fixed paylines. Released in August 2019, it drops you into a castle chamber straight out of Arthurian legend. King Arthur, Merlin, Guinevere, and Lancelot all appear on the reels alongside a progressive Free Spins round that I genuinely enjoy streaming.
If I'm honest with chat, the feature set here is narrow; you get Multiplier Wilds and free spins, nothing else. But what it does, it does well. High volatility, 96.53% RTP, and a 10,000x max win mean sessions can swing wildly. Visually the slot still holds up years later, with detailed character portraits and a moody medieval soundtrack that keeps the atmosphere thick.
Symbols and Paytable
Four Arthurian characters sit at the top of the paytable. King Arthur pays 25x your stake for five on a line, Guinevere gives 12.5x, and both Lancelot and Merlin award 7.5x. Below them you have carved stone card royals; A pays 4x, K and Q each pay 3x, while J and T sit at the bottom with 2x for five of a kind.
Holy Grail wilds are the real prize. Five across a payline returns 50x your bet before any multiplier kicks in. Excalibur stuck in stone is the scatter, and landing three or more of them triggers the bonus. Wilds substitute for everything except that scatter. Payouts are modest during regular play, so the multiplier mechanic carries most of the heavy lifting.

Bonus Features
On any base game spin, a slider above the reels can randomly assign a 2x, 5x, 10x, or 100x multiplier to every wild on the grid. I've seen the 100x pop up in base game on stream and chat goes absolutely mental, but it is rare. Even the 10x can produce solid hits when paired with a premium symbol line.
Landing 3+ Excalibur scatters starts you at Stage 1 with 5 Free Spins and 2x Multiplier Wilds. Every scatter collected during the round fills a progress trail. Gather 6 total swords and you move to Stage 2 with 5 extra spins and 5x wilds. Stage 3 needs 11 swords for 10x wilds. Collect 18 and you hit Stage 4; 5 more spins with a 100x wild multiplier. Each stage only begins after the previous one finishes.
I'd say reaching Stage 3 is realistic in a long session, but Stage 4 is a proper grind. The bonus triggers roughly once every 83 spins, which keeps things moving on stream. When that 100x wild does land during a high stage, the math is there for the full 10,000x. Just don't expect it every session.
Bonus Buy Options
A random multiplier of 2x, 5x, 10x, or 100x can be applied to all Holy Grail wild symbols on any spin, including the base game.
Land 3+ Excalibur scatters to trigger 5 free spins. Collect scatters during the round to progress through 4 stages with increasing wild multipliers: Stage 1 (2x), Stage 2 at 6 swords (5x, +5 spins), Stage 3 at 11 swords (10x, +5 spins), Stage 4 at 18 swords (100x, +5 spins).
RTP, Volatility and Max Win
96.53% RTP sits slightly above the industry average, which is a plus. Be aware that operators can choose lower RTP versions down to 84.63%, so always check before you play. Volatility is firmly high. Bets range from 0.10 to 100 per spin, and the max win caps at 10,000x your total stake. For viewers wondering about the pace, the base game can drag a bit between bonus triggers, typical of high-volatility titles.
