The Green Knight, Wild Falls, and The Sword and the Grail Excalibur are the strongest alternatives – all three share the escalating wild multiplier system that defines The Sword and the Grail. That original built its reputation on a progressive free spins round where wilds climb from 2x to 100x as you collect scatters across four ranks from Squire to King. The back-loaded bonus structure, where early spins feed later spins, is exactly what connects these picks.
Play’n GO built this slot on a 5×3 grid with 20 fixed paylines, a 96.53% RTP at the highest tier, and a 10,000x max win driven entirely by how far you progress through the bonus levels. If you enjoy the tension of watching a meter fill while your multiplier value hangs in the balance, these six alternatives capture that same rhythm at different price points and volatility levels.

|---|---|---|---|---|
| The Sword and the Grail | Play’n GO | 96.53% | 10,000x | High |
| The Green Knight | Play’n GO | 96.20% | 10,000x | High |
| Wild Falls | Play’n GO | 96.50% | 10,000x | High |
| The Sword and the Grail Excalibur | Play’n GO | 96.20% | 25,000x | Very High (10/10) |

| Leprechaun Goes to Hell | Play’n GO | 96.54% | 50,000x | High |
Play’n GO operates a five-tier RTP system across its catalogue, ranging from 84% up to around 96%, so always confirm which setting your casino uses before committing to a session.
The feature rhythm you’re really chasing
The Sword and the Grail is a bonus-heavy game that plays quiet until it doesn’t. Base game spins occasionally land Holy Grail wilds carrying random multipliers between 2x and 100x, but the real draw is the progressive free spins triggered by three Excalibur Sword scatters. You start at Level 1 with 5 spins and 2x multiplier wilds, then collect additional scatters to advance – six scatters push you to Level 2 with 5x wilds, eleven scatters reach Level 3 at 10x, and eighteen scatters unlock Level 4 where every wild carries a 100x multiplier. Each level awards five additional spins, meaning a full run through all four tiers delivers up to 20 spins with the highest multiplier active. On a €10 / £10 / $10 stake, the 10,000x ceiling translates to €100,000 / £100,000 / $100,000 – but you need a deep bonus run to get anywhere close.
1. The Green Knight
Why it matches
Same 5×3 grid, same provider, same 10,000x max win, and the same multiplier wild mechanic that can reach 100x during free spins. The Green Knight uses a Sword Wild that accumulates multiplier values as it moves across the reels during the bonus round, creating a left-to-right progression that mirrors The Sword and the Grail’s level-based escalation.
What sets it apart
The multiplier builds on a single walking wild rather than across all wilds simultaneously, making it less dependent on landing multiple wilds per spin and more about keeping the feature alive long enough for the multiplier to climb.
Ideal for
Players who want the same 100x multiplier ceiling with a slightly different route to get there.
Trade-off
The 96.20% RTP sits 0.33 points below The Sword and the Grail, and the single walking wild means fewer multi-wild paylines during any given spin.
2. Wild Falls
Why it matches
Wild Falls uses a Gold Rush free spins feature where multiplier wilds accumulate on the reels and grow in value with each cascade. The mechanic creates the same escalating tension – early spins build the foundation while later spins deliver the big multiplied payouts.
What sets it apart
The 96.50% RTP nearly matches The Sword and the Grail’s 96.53%, making it one of the closest statistical alternatives in the Play’n GO catalogue. The waterfall theme and cascading wild mechanic feel distinctly different despite sharing the same mathematical backbone.
Ideal for
Players who want near-identical RTP and max win potential but prefer wilds that stick and grow rather than level-based progression.
Trade-off
The base game hit rate can feel sparse, with long stretches between bonus triggers that test patience more than The Sword and the Grail’s occasional base game multiplier wilds.
3. The Sword and the Grail Excalibur
Why it matches
The direct sequel retains the Grail Wild multiplier system and the Sword Meter scatter collection mechanic. Every fifth Sword Scatter collected during free spins increases the multiplier tier and awards three additional spins, preserving the original’s progressive structure while adding Instant Prizes and a Round Table Wheel that determines your starting conditions.
What sets it apart
The max win jumps to 25,000x – two and a half times the original’s ceiling. Roaming Grail Wilds during free spins stick to the reels and move position each spin, creating compound win opportunities that the original lacks.
Ideal for
Players who have already mastered the original’s rhythm and want the same structure with higher upside.
Trade-off
Volatility is rated 10/10 compared to the original’s high-but-not-maximum rating, and the 96.20% RTP drops 0.33 points. The higher ceiling comes with harsher base game stretches.
4. King’s Mask Eclipse of Gods
Why it matches
King’s Mask Eclipse of Gods uses wild modifier mechanics where you choose which enhancement to apply during the bonus round. The selection element adds a strategic layer that echoes the progression through The Sword and the Grail’s four levels – you’re actively shaping how your bonus plays out rather than passively watching reels spin.
What sets it apart
The 20,000x max win doubles the original’s ceiling, and the choice-based modifier system means no two bonus rounds feel identical. The 96.29% RTP sits comfortably between the two Sword and the Grail entries.
Ideal for
Players who enjoy the wild-driven bonus structure but want more agency over how their feature round develops.
Trade-off
The lack of a visible meter tracking your progress removes the visual tension that makes The Sword and the Grail’s scatter collection so compelling during free spins.
5. Colt Lightning Firestorm
Why it matches
Colt Lightning Firestorm pushes sticky wilds with stacking multipliers to their logical extreme. During the bonus round, wilds lock in place and their multiplier values compound across subsequent spins, creating the same back-loaded payout structure where the final spins carry the most weight.
What sets it apart
The 50,000x max win is five times The Sword and the Grail’s ceiling, representing a serious step up in theoretical potential. The sticky wild mechanic means multipliers persist rather than resetting each spin.
Ideal for
Players chasing significantly higher ceilings who are comfortable with very high volatility and longer dry stretches between meaningful wins.
Trade-off
The 96.20% RTP is lower, and the volatility increase means the base game can punish shorter sessions. Budget at least 150x your stake per session to give the feature mechanics room to develop.
6. Leprechaun Goes to Hell
Why it matches
Leprechaun Goes to Hell delivers a dual free spins system where heaven and hell modes offer different risk-reward profiles, both featuring wild multipliers. The 96.54% RTP actually edges above The Sword and the Grail’s 96.53%, making it statistically the closest match on the list while offering a 50,000x ceiling.
What sets it apart
The choice between heaven (lower volatility, steadier returns) and hell (higher risk, bigger multipliers) lets you control how aggressively you pursue the max win. Few slots give you that level of session control.
Ideal for
Players who want the best RTP match combined with significantly higher theoretical potential.
Trade-off
The quirky leprechaun theme is a sharp departure from the medieval setting, and the hell-mode bonus rounds can burn through spins rapidly without meaningful returns if the multipliers don’t connect.
Which alternative fits your style
If your bankroll suits shorter sessions and you want the closest mechanical mirror, The Green Knight delivers the same 100x wild multiplier ceiling on the same grid format without asking you to learn new rules. If you’ve already worn out The Sword and the Grail and want the natural next step, the Excalibur sequel preserves every mechanic you know while pushing the max win to 25,000x – though the 10/10 volatility rating demands a larger starting balance. For players willing to trade medieval aesthetics for raw statistical value, Leprechaun Goes to Hell matches the RTP almost exactly while offering five times the payout ceiling.
What players usually ask
What slot is most similar to The Sword and the Grail?
The Green Knight shares the same provider, the same 5×3 grid layout, identical 10,000x max win potential, and wild multipliers that reach 100x during the bonus round. The core difference is how the multiplier builds – through a walking wild rather than scatter-driven level progression – but the session feel and payout structure align closely.
Are there slots with higher RTP than The Sword and the Grail?
At 96.53%, The Sword and the Grail sits near the top of Play’n GO’s range. Leprechaun Goes to Hell edges it slightly at 96.54%, and Wild Falls comes close at 96.50%. Most alternatives on this list sit in the 96.20% range, which is still above the industry average but noticeably below the original’s return rate.
What Play’n GO slots are like The Sword and the Grail?
Beyond the six listed above, Diamonds of the Realm continues the Arthurian theme with similar wild multiplier mechanics. Book of Dead offers the same high-volatility 5×3 format with expanding symbols during free spins, though it lacks the progressive level structure. Legacy of Dead refines that formula further with the ability to select multiple expanding symbols.
Can I play slots like The Sword and the Grail for free?
Every slot on this list is available in demo mode at casinos carrying Play’n GO titles. Free play versions use the same RNG and feature triggers as real money games, making them useful for testing whether an alternative’s bonus rhythm suits your preferences before committing funds.
Tiered recommendations
Start with The Green Knight if you want the closest one-to-one match in both mechanics and session feel. Move to The Sword and the Grail Excalibur when you’re ready for higher stakes and a 25,000x ceiling built on familiar mechanics. Graduate to Colt Lightning Firestorm or Leprechaun Goes to Hell when you want the multiplier wild concept pushed to its 50,000x extreme. Each step up brings more volatility and longer dry stretches, but the core thrill – watching wilds grow in value as a bonus round develops – stays consistent across every title on this list.
