Drawing Excalibur from the Lost Kingdom

Key takeaways

How Avalon: The Lost Kingdom slot Works

Lines and layout

Every spin uses the same 20-line structure on mobile and desktop, so you don’t need to relearn the grid. Regular symbols pay for 3, 4 or 5 matching symbols, except the Prince, which also pays for 2. I like that simplicity, because you can read most outcomes without opening the paytable every few spins. You still need patience, since simple lines don’t mean frequent strong hits.

Highlight: This is a true 20 fixed-payline slot on a 5×3 grid, not a ways or cluster game.

Symbols and pays

All symbol pays use multiples of the total bet, which makes the paytable easier to compare. The top end looks clear, but the low cards mostly soften losses rather than changing a session.

• Prince: 40x for 5, 5x for 4, 1x for 3, and 0.1x for 2.
• Morgana and Meliuzina: 30x for 5, 3.75x for 4, and 1x for 3.
• Grail and Jewel: 25x for 5, 2.5x for 4, and 0.5x for 3.
• A and K: 7.5x for 5, 1x for 4, and 0.25x for 3.
• Q and J: 5x for 5, 1x for 4, and 0.25x for 3.
• 10 and 9: 3.75x for 5, 0.5x for 4, and 0.25x for 3.

The stone Gate acts as the Wild and substitutes for every symbol except the Scatter. It also pays 40x for 5 of a kind on its own, so you notice it when it lines up. The Excalibur sword Scatter has no direct paytable value, since its job is to trigger Free Spins from anywhere on the reels. The base game stays simple to follow, while the bonus features carry most of the volatility.

Theme & First Impressions

The theme is polished and clear, even though the medieval fantasy angle feels familiar. Avalon: The Lost Kingdom is an Arthurian fantasy slot from BGaming, with a mossy stone arch around the reels and mist rolling across the ground. A sword in the stone stands on the right side, which gives the screen an instant Excalibur identity. You get the point fast, and that matters when you are testing long autoplay runs.

Arthurian setting

The premium portraits do most of the storytelling. You see a crowned prince, the dark-haired Morgana, and the blonde Meliuzina at the top of the symbol ladder. A golden grail and silver jewelled ring sit just below them, while the low cards appear as slim carved metallic values. Keepers Of The Secret feels darker and more sealed-off by comparison, while this game goes for open stone ruins and visible fantasy icons.

Notable Detail: Arthurian stories often hinge on chosen weapons and hidden heirs, so the sword-in-stone framing fits the bonus chase neatly.

First visual read

Free Spins Round

Trigger requirements

The trigger ladder is simple: 3 Scatters start 10 free spins, 4 Scatters start 12, and 5 Scatters start 15. Scatters can land anywhere, so you don’t need them on an active line. I like that structure because it gives you a clean visual sweat when two swords land early. Still, my session showed that a short sample can pass without any bonus entry.

Risk Note: Because this is a high volatility slot and my 100-spin test didn’t trigger Free Spins, don’t assume the bonus can arrive quickly.

What changes inside

The round combines three moving parts: the Fateful Wild selection, a random 2x to 7x multiplier, and the random Excalibur feature. That sounds layered, but each part has a clear role once you separate it. The Wild choice changes the symbol mix, the multiplier boosts paying spins, and Excalibur can drop extra Wilds. The Free Spins round sounds lively, but the trigger can feel elusive in a short session.

Fateful Wild Choice

The three picks

Why it matters

Random Multiplier

2x to 7x

A small line hit can become more interesting when the game applies 5x, 6x, or 7x. That doesn’t make the bonus safe, because the multiplier needs a paying spin underneath it. You should treat the range as extra punch rather than a promise of a strong round. I like multipliers best when they stay transparent, and this one does.

Expert Advice: Treat the multiplier as a per-spin boost, not a feature that guarantees momentum across the whole round.

RTP, Volatility & Our Test

Simulator projection

The SatoshiHero Slot Simulator modelled 1,000 spins at one bet unit from 94.56% RTP, the 3,812x cap, and the high volatility band. The median run finished 82.7x down, while nine out of ten runs landed between 331.1x down and 341.4x up. Roughly 18% of spins paid something in the model. A feature-sized win appeared about once in 46 spins, and a very large win appeared about once in 1,799 spins.

Notable Detail: In the simulator, nine out of ten modelled 1,000-spin runs landed between 331.1x down and 341.4x up, which shows why bankroll size matters.

Our 100-spin session

My live demo snapshot used the $0.20 default bet across 100 autoplay quick spins. The balance moved from $1,000.00 to $989.41, which left me 52.95x down. Free Spins didn’t trigger, and my biggest logged win reached 5.25x the bet. I treat that result as a snapshot, not a verdict on what your next session can do.

Theoretical RTP is the operator-published return figure. A single live or demo session doesn’t change that theoretical RTP. Simulator outputs and bonus behaviours are illustrative, not promises, and feature-return differences sit inside the game design rather than guaranteeing short-term results. The numbers point to a swingy slot with clear mechanics but uneven short-session pacing.

Summing It Up

Avalon: The Lost Kingdom gives you clean 20-line play, clear Arthurian symbols, and a bonus structure with several moving parts. Its main drawback is the tension between high volatility and a 3,812x ceiling, which makes the risk feel sharper than the top prize suggests.

My Call

Classic line-slot fans can enjoy the clean setup, especially if they like Free Spins chases with Wild choices. Expect a measured base game, not a constant bonus parade. Keep your stake low if you want enough spins to ride out cold sections.

I like the readable grid and the way the premium portraits connect to the Fateful Wild choice. I don’t like how flat my 100-spin test felt without a bonus trigger, even though the small hits softened the slide. The strongest idea sits inside Free Spins, so the base game can feel like a waiting room.

Avalon: The Lost Kingdom slot is checked regularly so the guide stays aligned with tested play and published math. The core appeal remains simple: easy line wins, a clear Arthurian theme, and a bonus round that may carry the real drama.

Pros:

• 
  Readable layout: Fixed lines make every spin easy to follow.
• 
  Clear bonus rules: Free Spins combine Wild choice, multipliers, and Excalibur drops.
• 
  Strong theme clarity: Stone, mist, and portraits support the Arthurian mood.
• 
  Useful demo test: Real spin results show the base game’s slower pace.

Cons:

• 
  Bonus can hide: My 100 spins produced no Free Spins trigger.
• 
  Restrained ceiling: The 3,812x cap feels modest for high volatility.
• 
  Quiet base play: Small wins soften losses but rarely excite.

Best For: Patient line-slot players get the most from this game when they value clear reels and a slow Free Spins chase. You should be comfortable with dry patches, modest base-game hits, and the chance that the bonus doesn’t appear in a short session.
