Lord Merlin and the Lady of the Lake Slot Review
Play’n GO have established themselves as masters of the book slot format, and this 2021 release positions itself as a worthy successor to the original Rise of Merlin. Rather than chasing the industry’s obsession with Megaways mechanics, the developer has refined what they do best–crafting high volatility books with generous win potential and polished presentation. Lord Merlin and the Lady of the Lake takes players on a journey through Arthurian legend with Merlin and Vivian (the Lady of the Lake) as central characters, set against a picturesque lakeside backdrop with transparent reels and stunning graphics. What sets this apart is the innovative Excalibur Spins feature, which locks expanding symbols in place during bonus rounds and offers unlimited retriggering potential. This is a game designed for players comfortable with high volatility gameplay–those seeking big win potential over frequent smaller wins. The theme resonates strongly, the mechanics are engaging, and the payouts genuinely exceed Play’n GO’s standard offerings, making this an exciting entry in the book slot landscape.
Base Game & Features
Lord Merlin operates on a 5×3 grid with 10 paylines, delivering a familiar structure that appeals to both experienced players and those new to book slots. The game uses standard left-to-right payline mechanics, making wins straightforward to identify. Where the base game distinguishes itself is through its expanding symbol mechanic combined with high volatility–the trade-off is deliberate. The base game feels sparse by design, lacking the constant small feature triggers found in modern slot releases. This isn’t a flaw; it’s intentional design philosophy. High volatility means longer waits between wins, but when payouts land, they carry genuine weight. Players will quickly recognise this characteristic of the book slot format, particularly one tuned toward volatility.
Symbol Values & Paytable
The symbol set is thematically rich and mechanically clear. The Lady of the Lake (Vivian) serves as both the wild symbol and the highest-paying regular symbol, offering rewards up to 10,000x your stake–a significant premium compared to Play’n GO‘s typical 5,000x ceiling. This alone positions Lord Merlin as a premium release within the developer’s catalogue.
The paytable breaks down into two tiers. High-paying symbols include Merlin, Merlin’s Staff, Wizard Hat, and the Lion Crest, each offering respectable multiples when landing across paylines. The low-paying symbols–standard card denominations A, K, Q, J, and 10–fill out the remaining positions. All symbols except the scatter (Sword) can be substituted by the Lady of the Lake wild.
The Gamble Feature
A traditional gamble feature is present for players seeking to double down on wins. After any paid spin, players can attempt to multiply their winnings by guessing either the colour of a playing card (doubling the win) or the suit (quadrupling it). The feature continues until achieving 5 consecutive correct predictions or reaching a 2,500 coin limit, whichever comes first. This is a low-risk optional feature that adds a brief moment of interactivity to the base game without feeling forced.
Lord Merlin Free Spins & Bonus Features
The bonus round is where Lord Merlin demonstrates its true potential and explains why base game simplicity exists as intentional design. Three or more Sword symbols (scatters) trigger 8 free spins, immediately entering a round rich with possibility. What happens during these spins is where the innovative mechanics shine through. At the start of each free spin, a random symbol is selected to become the expanding symbol for that spin, meaning it fills entire reels when it lands. This keeps the round dynamic–the specific expanding symbol changes constantly, requiring players to adapt rather than relying on predictable patterns. Free spins can be retriggered indefinitely, with each landing of 3+ additional scatters granting another cycle of 8 spins.
During free spins, a single Sword symbol now acts as a wild, opening additional win combinations beyond the expanding symbol mechanic. The potential here is substantial, with players capable of landing up to 500,000 coins from a single bonus round before considering any multipliers from Excalibur Spins.
The Excalibur Spins Innovation
This is Lord Merlin’s signature feature and its clearest differentiator from Rise of Merlin. During free spins, landing 2 or more wild Scatters triggers Excalibur Spins. Rather than simply awarding additional spins, Excalibur Spins locks the current free spins round’s expanding symbol permanently in place. From that point forward, each additional scatter lands awards exactly one spin, with continued retriggering potential–there is no maximum spin limit during Excalibur Spins. The locked expanding symbol means every subsequent spin carries the expanded symbol already filling those reels, dramatically increasing win potential on each spin.
The excitement here is genuine and well-earned. Players who’ve experienced traditional expanding symbol mechanics understand the appeal–imagine the expanding symbol locked permanently in place whilst continuing to retrigger free spins. A full-screen fill becomes genuinely possible, and the unlimited retriggering potential means exceptional bonus rounds can extend dramatically. This feature explains the 10,000x maximum win potential. It’s not theoretical; it’s achievable through sustained Excalibur Spins retriggering combined with locked expanding symbols covering substantial portions of the reels.
Community feedback on Excalibur Spins leans overwhelmingly positive, with players highlighting the excitement and strategic depth it adds. Some note that the feature does slow the bonus slightly–there’s more to process than simple expanding symbols–but the trade-off of increased big-win potential more than compensates. A minority of players prefer simpler mechanics, but the innovation clearly resonates with the broader audience seeking something fresh within the book slot category.
Our Honest Verdict
Lord Merlin and the Lady of the Lake succeeds as an enhanced follow-up to Rise of Merlin, offering genuine innovation without abandoning the book slot formula. The 10,000x maximum win potential genuinely exceeds Play’n GO’s typical offerings and positions this as a premium release–this isn’t merely theoretical; the Excalibur Spins feature was explicitly designed to achieve this ceiling. The innovative Excalibur Spins mechanic with locked expanding symbols and unlimited retriggering is the standout feature, adding depth and excitement that elevates the game beyond standard expanding symbol releases. Visually, the game is stunning. The Arthurian theme with Merlin and Vivian feels purposeful rather than generic, the lakeside setting displays excellent production value, and the transparent reels against the background create a unique visual presentation.
However, the game’s strength is also its defining limitation. High volatility gameplay means the base game can feel sparse and tedious–there are no base game feature triggers, no modifiers, just reel spins waiting for the bonus to activate. This is entirely intentional design, but it means players must be comfortable with extended dry spells between wins. The high volatility also means actual payouts frequently fall significantly short of the 10,000x theoretical maximum, requiring substantial bankroll reserves and genuine volatility tolerance. Playing through the base game requires patience; the reward arrives in the bonus round.
Lord Merlin is familiar enough to keep experienced high-volatility players happy, yet simple enough that casual gamers can understand and enjoy the mechanics. The game appeals clearly to those seeking big win potential over frequent smaller wins. Series fans of Rise of Merlin will appreciate the enhanced payouts and new mechanics. For casual base-game-focused players, there are superior options with more consistent action. The verdict is straightforward: this is an exceptional book slot for players who understand and accept high volatility gameplay, with genuine innovation in the Excalibur Spins feature and premium win potential backing the offering. It’s a worthy addition to the Rise of Merlin family and a premium entry in Play’n GO’s catalogue.
