Across 460 base-game spins at a 10-credit stake, the Round Table Wheel never turned. What did turn up were the two multipliers Play'n GO wired into this grid: a Sword Meter scaling every King's Prize, and a Grail Wild that multiplies any win it joins and, in Free Spins, sticks and may wander.
This extremely volatile slot is all about the free spins mechanic. My session ran 460 spins at 10.00, took the balance from 25,000.00 to 21,460.00, and its biggest win was 120.00, 12.0x the stake. It is constructed using 5 reels and 20 paylines, and the grid is 3 rows deep. All wins pay left to right on adjacent reels from the left-most reel, and only the highest win per line is paid.
On the reels, you'll spot 10 to A card ranks as well as Knights, Wizards, Queens, and Kings. Alongside them, King's Prizes land on the reels as instant cash prizes, and each one is multiplied by the Sword Meter. The most lucrative of all symbols, however, is the Grail. It returns the most for a set of five bearing the x100 multiplier. The multiplier on a Grail can be x2, x5, x10 or x100, and the symbol's own payout rises with that figure. The Grail also acts as the wild. It can land as a Multiplier Wild on any spin and multiplies any win it enters by the figure displayed on it. The rules say the Grail may land that way in the base game and will land as a Multiplier Wild during Free Spins.
I'll jump straight to the Free Spins bonus, which is triggered when 3 or more Sword Scatters land. Nothing in my 460 spins got that far, so the sequence below is taken from the rules. The Round Table Wheel will then decide the starting free spins and Sword Scatters, and it's also possible to gain 3 additional free spins for every 5 Sword Scatters collected. The same 5 Sword Scatters also unlock the next Multiplier stage, and the Sword Meter's stages run x1, x2, x3, x5 and x10.
The free spin mechanic is all about hitting Grail Wilds, and to help along the way, a Wandering Grail Wilds mechanic has been incorporated. King's Prizes can land during Free Spins too, and any that do are awarded. All wilds are sticky. They may shift in any direction, and each can bear a multiplier from the Sword Meter. If more than one Grail Wild lands, they all move in the same direction.
The Minty Breakdown: The build puts its multipliers in two places, the Grail on the wild and the Sword Meter on King's Prizes, and across 460 base-game spins at a 10-credit stake the biggest single hit was 12x the stake.
The Sword and the Grail Excalibur is not all that poor. Of my 460 spins, 63 paid, 27 of those paid less than the 10.00 stake, and the longest run without a win lasted 47 spins. There are no genuine shocks, inventive mechanics, or anything I haven't witnessed before, and in that respect the game is fairly ordinary. Legendary Excalibur from Red Tiger Gaming is built on the same Excalibur legend, and The Green Knight is another Play'n GO title.
The Sword and the Grail Excalibur is not a game I'm going to hurry to play.
