The Sword and The Grail Slot Review

Sword and Grail: the two symbols that matter

The Grail is the wild. It can land on any reel and substitutes for every symbol except the Sword. On any spin, base game included, it can also show up as a Multiplier Wild worth x2, x5, x10 or x100. A x100 Grail completing a win turns an ordinary line into something far larger, which makes this symbol the main source of big base-game outcomes.

The Sword is the scatter. Three or more in view trigger the free spins, and any swords beyond the third push the round forward before it even begins.

From squire to knight: the free spins

The feature is progressive and has four rounds. It opens with five free spins, and the number of swords on the triggering spin decides which stage you start from: more swords, a later stage.

During the round, swords keep being collected. Each time enough are gathered, the feature advances to the next stage, and throughout the round a multiplier is added to any Grail that lands. Reaching all 18 swords takes the round to its final stage, where the reward is a x100 multiplier.

That structure has a clear consequence. The largest stated reward waits at the last stage, so the potential is weighted towards the end of the quest. A round that starts low and collects few swords will end without seeing what the top stage offers.

Five settings, one game

The studio offers five RTP versions: 96.53%, 94.5%, 91.32%, 87.35% and 84.63%. Their house edges run 3.47%, 5.5%, 8.68%, 12.65% and 15.37%. Translated to money, $1,000 wagered costs around $34.70 at the top setting, then $55, $86.80, $126.50 and $153.70 as the versions step down.

For a 100-spin session at $1, the average cost is $3.47 at 96.53% and $15.37 at 84.63%. At $0.20 the pair is $0.69 and $3.07; at $5 it is $17.35 and $76.85. Since the same game can carry any of these figures, the paytable or help screen is the place to confirm which one applies.

Volatility is Very high. There is no published max win in our data, despite the x100 multipliers in play.

A follow-up, The Sword and the Grail Excalibur, came out in 2024 at 96.2% and is also rated Very high. Other 2019 Play'n GO titles with similar profiles include Rise of Merlin at 96.58%, Firefly Frenzy at 96.59% and Contact at 96.55%, all Very high as well. None of these comparisons has a maximum win recorded in our catalogue, so RTP and volatility are the only shared yardsticks.

Before you take up the sword

This game suits players who enjoy a long-term goal inside a bonus and accept that the reward is weighted towards the end of it. Very high volatility and a top prize locked behind 18 swords mean many rounds will finish early. A modest stake and a firm limit fit that profile, and the free demo shows the stage system before any money changes hands.
