Avalon X (ELK Studios) Slot Review

Avalon X: Slot Overview 

Avalon X is ELK Studios’ bold new reimagining of its much-loved Avalon universe, a mystical world that first came to prominence through the studio’s wildly successful Gold series. Known for its “X” spin-offs such as Pirots X and Katmandu X, ELK has again taken the letter and infused it into a thematic continuation—this time breathing new life into a fantasy adventure setting rooted in ancient mythology, enchanted ruins, and powerful relics. 

Released on September 2, 2025, Avalon X is built on a rich formula of 6 reels, 7 rows, and a Cluster Pays system powered by avalanche mechanics, allowing symbols to tumble, merge, expand, and chain together in explosive patterns. While the original Avalon Gold leaned heavily on its Mystery Box mechanic, Avalon X pushes deeper into that feature, blending it with global multipliers, Big Symbols, Holy Strikes, and the powerful X-iter bonus buy system. 

The world of Avalon X is one reclaimed by nature but still echoing ancient magic. Crumbled stone towers, overgrown archways, and shimmering waterfalls set the scene for a game that thrives on mystery and the echoes of a once-mighty kingdom. ELK has crafted a sequel that feels familiar yet elevated, giving players a luxurious fantasy playground where clusters blossom, cascading wins trigger global multipliers, and Mystery Boxes sit poised to unleash their arcane secrets at any moment.

Design and Graphics 

Avalon X is stunning—one of ELK’s most atmospheric visual works to date. The game is set within an enchanted woodland sanctuary where ruined architecture meets lush greenery. Waterfalls pour gently in the background, fireflies drift across stone platforms, and moonlight illuminates ancient pillars that frame the reels. The color palette leans heavily into cool blues, greens, and amethyst purples, creating an ethereal setting that feels calm yet mysterious.The symbols include four low-value animal icons and four high-value knight symbols, each depicted with clean detail and distinct personality. The knights—armored and majestic—reflect Avalon’s mythical lore, while the animals add thematic texture. 

Big Symbols (up to 4×4) land with heavy, rune-enhanced stone frames and crash down through smaller icons, smashing 1×1 symbols as they drop. The global multiplier frame above the grid—often glowing with fiery or arcane energy—adds an extra layer of visual impact as its value increases. 

Every animation is polished: Mystery Boxes pulse with golden light, avalanches cascade smoothly, and Holy Strikes flash across the grid in brilliant energy bursts. ELK continues to prove its mastery of pairing fantasy themes with modern visual flair.

Gameplay Mechanics 

Avalon X uses a Cluster Pays system on a 6×7 grid, creating wins by landing clusters of 5 or more matching symbols that connect orthogonally. Winning clusters are removed via the avalanche mechanic, allowing new symbols to fall into place and potentially continue the combo. 

Avalanche Mechanic with Wild Generation 

Each winning cluster generates a wild symbol in one of the empty spaces. If multiple wilds form as part of different clusters, their multipliers combine when they merge. Regular wilds carry a value of 1, while multiplier wilds can significantly increase payout potential. 

Avalanche momentum continues until no new wins appear, at which point the grid resets—except in special modes where persistence is active. 

Cluster Values 

Low-value animals: 0.05x–1x for clusters of 5+ 

High-value knights: up to 50x for large clusters (16+ symbols) 

All multiplier wilds in a win combine and multiply the final cluster payout before the global multiplier comes into play. 

Hit Frequency: 23.8% 

Avalon X delivers reasonably frequent wins for a high-volatility game.

Sound and Music 

The audio design is enchanting and cinematic. Avalon X features soft choral harmonies, faint bells, and atmospheric forest ambience. It invokes the feeling of walking through sacred ruins, with a soundtrack that grows more dramatic as global multipliers rise or features activate. 

Avalanche tumbles are accompanied by crystalline chimes, Mystery Boxes emit mystical hums, and Holy Strikes crackle with magical energy. The sound design significantly amplifies the sense of magic and ancient power throughout the experience. 

In bonus rounds and Super Bonus modes, the music intensifies with deeper orchestral elements, building excitement and momentum as multipliers climb ever higher.

Bonus Features 

Avalon X is stacked with mechanics, many adapted and enhanced from earlier ELK titles such as Avalon Gold, Katmandu X, and Propagandal.Global Multiplier & Big Symbols 

Avalon X’s global multiplier is one of the game’s main attractions: 

Each low-value winning cluster increases the global multiplier by +1 

Each high-value winning cluster increases it by +2 

The multiplier persists through avalanches but resets between paid spins 

When Big Symbols (1×1, 2×2, 3×3, or 4×4) land, they crush smaller symbols and count as the number of tiles they occupy, contributing to larger clusters. 

After all cluster payouts, the global multiplier is applied, resulting in potentially massive wins.

Mystery Boxes 

Mystery Boxes play a crucial, expanded role in Avalon X. They are blocking symbols that remain on the grid until triggered.
If 5 or more Mystery Boxes are present and no further wins occur, they activate and reveal: 

Coin values 

Collect – gathers all revealed coin values 

Redrop – respins the grid and reactivates Mystery Boxes 

Global Multiplier Spreader – boosts coin values based on the global multiplier 

Pay symbols, wilds, or special effects 

This mechanic brings a mixture of suspense and explosive reveal potential.

Holy Strike 

Holy Strike replaces random symbols anywhere on the grid with: 

Regular wilds 

Multiplier wilds 

Or Mystery Boxes 

It cannot replace scatters, supers, wilds already present, or Mystery Boxes already active.
This is a high-impact feature, especially during free spins.

Free Spins 

Landing 3 scatters awards 7 free spins, with significant enhancements: 

The global multiplier becomes persistent throughout the bonus 

Unopened Mystery Boxes remain sticky between spins 

Each landed scatter or super scatter awards +2 additional free spins 

Super Free Spins (upgraded mode) guarantee one Holy Strike every spin 

Triggering with 2 scatters + 1 super scatter automatically upgrades to Super Spins 

This feature can snowball dramatically as multipliers climb.

X-iter (Bonus Buy Options) 

Avalon X offers five X-iter modes:Bonus Hunt – 3× bet 

Holy Strike – 25× bet 

5 Guaranteed Mystery Boxes – 50× bet 

Bonus – 100× bet 

Super Bonus – 500× bet 

The Super Bonus is the most explosive mode, but also the most costly, offering persistent modifiers and extremely high potential.

Betting Options and Payouts 

Min Bet: €0.20 

Max Bet: €100 

RTP: 94% 

Volatility: High (7/10) 

Max Win: 10,000x 

Paylines: Cluster Pays 

Hit Frequency: 23.8% 

While the RTP is on the lower side, this is typical for ELK’s X-iter-focused games. The 10,000x max win places Avalon X comfortably within high-volatility expectations, supported by multipliers that can snowball rapidly under the right conditions.

Conclusion 

Avalon X is a lush and mystical continuation of the Avalon legacy, combining familiar mechanics with refined pacing, memorable visuals, and an impressive feature set. The global multiplier, Wild merging, Big Symbols, and Mystery Boxes all integrate seamlessly, creating a gameplay loop that feels consistently rewarding and full of potential. 

It may not reinvent ELK Studios’ formula, as it borrows heavily from predecessors like Avalon Gold, Katmandu X, and Propaganda, but what it delivers is polished, cohesive, and engaging. The Super Bonus is especially thrilling, and free spins with persistent multipliers offer some of the game’s most exciting moments. 

For players who love cluster pays, escalating multipliers, and beautifully crafted fantasy themes, Avalon X stands as a worthy successor to Avalon Gold—and one of ELK Studios’ strongest releases of 2025.
