The Sword and the Grail Excalibur Slot Review
Play’n GO have solidified their reputation as developers who understand the Arthurian Legend franchise. After the success of their 2019 original, they return with The Sword and the Grail Excalibur, a sequel that builds on established mechanics while introducing fresh elements aimed at high-volatility enthusiasts. This 5-reel, 3-row video slot launches with an impressive 25,000x maximum win cap and a challenging progression system that rewards scatter collection across free spins. If you’re seeking a slot that demands engagement and punishes careless play, this Excalibur-themed adventure delivers exactly that.
Base Game & Features
The Sword and the Grail Excalibur operates on a straightforward 5-reel, 3-row grid with 20 fixed paylines. This structure rewards players with 3 to 5 identical symbols landing from left to right, creating a traditional win mechanic that feels familiar yet purposeful. The reel configuration may lack complexity compared to some 6-reel alternatives, but it serves a clear design intent: keeping focus on the scatter and multiplier mechanics rather than overwhelming players with multiple directions.
The symbol set divides between high-paying and low-paying tiers. Four premium symbols dominate the top payouts, with the highest delivering 15x your stake for a full 5-symbol combination. Standard playing card values (A, K, Q, J, 10) fill the lower tier, offering modest returns that keep base game spins viable without delivering the explosive wins the feature rounds promise. Both tiers work in tandem, ensuring the base game remains engaging whilst reserving the truly transformative mechanics for free spins.
Special Symbols & Multipliers
The most distinctive element of The Sword and the Grail Excalibur emerges through its special symbols. Grail symbols function as wilds, substituting all symbols except scatters. However, they’re not ordinary wilds—their multiplier power scales based on the Sword Meter, which activates exclusively during free spins. This design choice creates asymmetry: base game wilds deliver straightforward substitutions, while free spins transform them into multiplier machines.
Sword Scatters (represented as the Excalibur symbol) trigger the entire bonus system. Three or more scatters across any reel position launch free spins and activate the progression mechanics that define this slot’s personality. Unlike traditional scatters that offer instant payouts, Excalibur symbols here serve a singular purpose: unlocking the round table wheel and advancing the Sword Meter. It’s a focused design that channelises all excitement into the bonus experience.
Instant Prizes & Base Game Modifiers
The base game remains relatively static, lacking the random modifiers that dominate contemporary releases. There are no expanding wilds, no symbol multipliers triggered randomly, no auxiliary progression systems. What you see is what you get—20 paylines, fixed symbols, and standard mechanics. This minimalism could disappoint players accustomed to 4ThePlayer or Big Time Gaming’s feature-rich approach, though it provides clarity: win or chase the bonus. That directness has merit, even if it means base game sessions feel somewhat austere before the free spins activate.
The Sword and the Grail Excalibur Free Spins
Free spins are where The Sword and the Grail Excalibur transforms. Triggering 3 or more Sword Scatters activates the Round Table Wheel, a unique entry mechanism that determines both your starting spins and initial scatter count. The outer wheel awards 8, 10, or 12 free spins—not the “up to 15” you might hear elsewhere. The inner wheel simultaneously awards 0, 1, 2, 3, or 4 starting scatters. Crucially, there’s an inverse relationship: more spins mean fewer starting scatters. This design ensures balance—high spin counts don’t automatically translate to easier progression, creating genuine strategic tension.
The Sword Meter Progression Mechanic
The centrepiece of free spins is the Sword Meter, a collection-based progression system that escalates multiplier values as you accumulate scattered symbols. Every 5 scatters collected during free spins unlock the next multiplier tier and award an additional 3 spins. The meter progresses through four multiplier levels: 2x, 5x, 10x, and 100x. These multipliers apply to both Grail Wilds and instant prize symbols, creating multiplicative potential that skyrockets as the Sword Meter climbs.
However—and this is critical—reaching each tier demands discipline and fortune. Collecting 5 scatters consistently requires extended free spin sessions. Players chasing the 100x multiplier can spend an entire bonus round grinding through levels, watching the Sword Meter progress incrementally. For some, this progression creates engaging gameplay. For others, it feels punishing: requiring too much scatter luck to achieve the transformative multipliers that justify the high volatility. The mechanic is neither broken nor revolutionary; it’s a deliberate design trade-off that separates patient players from those expecting rapid escalation.
Roaming Wilds & Retriggers
During free spins, Grail Wilds adopt roaming characteristics, moving in unison—either up, down, left, or right—across the game board. They remain sticky throughout the feature round, persisting until they eventually fall off screen. These roaming wilds embody the multiplier power dictated by your current Sword Meter level, transforming single wilds into explosive win generators when you’ve progressed to higher tiers. A wild at 100x multiplier can deliver staggering payouts; a wild at the base 2x tier delivers modest gains. This scaling creates natural progression tension: early free spins feel sedate, later spins (if you reach them) feel transformative.
Retriggers are achievable but demanding. Collecting 5 additional scatters during free spins awards +3 spins and advances your Sword Meter. This mechanism keeps free spins alive longer for disciplined scatter collectors, though it’s not particularly generous. You’re not triggering free spins every other spin—you’re grinding scatter by scatter, turn by turn, hoping the RNG cooperates. That’s the intended experience: high volatility that demands extended sessions and bankroll depth to navigate.
RTP & Volatility
The Sword and the Grail Excalibur carries a default RTP of 96.20%, placing it comfortably within mainstream operator standards. Operator-specific configurations exist at 94.20%, 91.20%, 87.20%, and 84.20%, allowing casinos to select their preferred margin. Always verify which RTP version your casino operates—the difference between 96.20% and 87.20% is substantial over extended play.
Volatility reaches the maximum threshold at 10 out of 10, representing the most aggressive classification available. This isn’t theoretical—the mechanics confirm it. Your base game will feel long and barren. Free spins will demand extensive scatter collection before escalating into big multiplier territory. Maximum win probability sits below 1 in 1 billion, ensuring even extended sessions rarely glimpse the 25,000x cap. Players with modest bankrolls, those preferring consistent smaller wins, or casual slot enthusiasts should consider substantially tamer offerings. This slot is engineered for high-roller mentality: those comfortable with extended dry spells in pursuit of explosive potential.
The bet range spans £0.10 to £100 per spin, covering 17 distinct stake levels. This flexibility makes the slot technically accessible to casual players while accommodating serious high rollers. At maximum bet, the potential win reaches £2,500,000—a figure that captures attention, even if achieving it remains astronomically unlikely.
Our Honest Verdict
The Sword and the Grail Excalibur delivers exactly what Play’n GO intended: a high-volatility sequel that intensifies the progression mechanics of the original whilst maintaining the Arthurian Legend aesthetic. The 25,000x win potential, roaming wilds, and Sword Meter progression create meaningful feature gameplay. This isn’t a slot that rewards button-pushers; it demands engagement with the progression systems and acceptance of extended volatility swings.
Against its strengths, there are notable limitations. The absence of bonus buy or ante bet features removes player agency regarding feature access—you must chase naturally, with no acceleration option. The base game feels sparse compared to contemporary releases, lacking random modifiers or session variety. Reaching higher Sword Meter multipliers demands scatter luck that many sessions won’t provide, meaning the 100x multiplier remains a theoretical aspiration rather than realistic expectation. The 20-payline structure feels conservative alongside modern 1,024-way alternatives, potentially frustrating players accustomed to multi-direction wins.
For its audience—high-volatility enthusiasts familiar with Play’n GO’s design philosophy, players comfortable with sparse base games and feature-focused mechanics, those with sufficient bankroll to weather dry spells—The Sword and the Grail Excalibur represents a compelling offering. The 96.20% default RTP supports extended play, and the Sword Meter creates genuine progression narrative. However, players seeking consistent action, those chasing bonus buy convenience, or casual enthusiasts should explore alternative releases. This sequel will more than suffice for its intended demographic, though broader appeal remains limited by its uncompromising volatility design.
