Avalon II Slot Review

Avalon II: The Quest for the Grail is Microgaming’s sequel to one of its most enduring fantasy-themed slots, swapping a handful of fixed paylines for a sprawling 243-ways-to-win engine and an eight-level bonus hunt that still holds up well over a decade after launch. If you enjoy Arthurian legend, chunky multipliers and a free spins structure with real depth, this is one of the studio’s most rewarding classics to settle into.

How Avalon II Plays

Avalon II moves away from the traditional fixed-payline format in favour of a 243-ways-to-win structure. This means you don’t need matching symbols to line up on a specific payline — instead, a win is formed whenever enough matching symbols land on adjacent reels from left to right, starting on reel one. It’s a mechanic Microgaming has used across dozens of titles since, and it suits a game this symbol-dense because it rewards near-misses far less harshly than a rigid payline grid would.

The reels are populated with a mix of card-suit symbols (low pays) and Arthurian characters as the premium tier. The Avalon II logo is the top-paying symbol, followed by King Arthur, Merlin the magician, Guinevere, Morgan and the Black Knight. Landing five of the logo symbol across a way pays the most in the base game, while the card-suit symbols — spades, hearts, diamonds and clubs — fill in the smaller, more frequent wins that keep the balance ticking over between bigger hits.

Medium volatility is the right label for this one: you’ll see a reasonably steady stream of small-to-moderate wins in the base game, with the real upside locked behind the bonus feature rather than base-game multipliers or wilds doing the heavy lifting.

The Grail Bonus: Eight Paths to the Holy Grail

The Grail Bonus is triggered by landing three or more Holy Grail scatter symbols anywhere on the reels, and it’s genuinely one of the more inventive bonus structures Microgaming has produced. Rather than dropping you straight into a single free spins round, the game opens a quest map with eight distinct bonus levels to choose from — each one a different “leg” of the journey toward the Grail, with its own mechanic and risk/reward profile.

• Merlin’s Enchanted Spins — free spins with rolling reels and a progressive multiplier that climbs with consecutive wins.
• Lady of the Lake — a pick-me bonus offering instant cash prizes.
• King Arthur’s Free Spins — free spins featuring trailing wilds that stack across the reels.
• The Black Knight’s Challenge — a confrontation-style pick feature with escalating rewards.
• Morgan’s Spellbook — a mystery pick round with mixed cash and multiplier outcomes.
• Guinevere’s Favour — another pick-me style bonus with varied prize tiers.
• The Round Table — a wheel-style bonus with set cash multiplier segments.
• The Quest for the Grail (final level) — the headline free spins round, built around rolling reels and the biggest progressive multiplier ceiling in the feature.

You won’t be able to access every level on your first trigger — some are unlocked progressively as you work through the quest, which gives the bonus a sense of long-term progression rather than a flat, repeatable free spins round. This is the part of Avalon II that rewards patience: players who stick with a session long enough to see the later levels generally rate the feature far more highly than those judging it from a single trigger.

Why Avalon II Still Holds Up

Plenty of 243-ways slots from the early-to-mid 2010s feel dated now, but Avalon II’s bonus depth is the reason it’s still in regular rotation at Microgaming-powered casinos. A few things set it apart:

• Genuine feature variety — eight different bonus mechanics beats the single free-spins-plus-multiplier template most slots from this era rely on.
• Medium volatility that suits longer sessions — you’re not waiting through hundreds of dry spins for the feature to matter, nor is it so swingy that bankroll management becomes guesswork.
• Solid theme execution — the Arthurian legend art style, animations and sound design were a clear step up from the original Avalon, and it still looks clean on modern screens.
• Wide availability — because it’s a long-standing Microgaming title, it’s stocked by most licensed casinos running the Microgaming or Quickfire catalogue, including a number of crypto-friendly operators.

Where to Play Avalon II

Avalon II is widely available at reputable Microgaming-powered casinos, many of which also run strong welcome packages and free spins promotions that pair well with ways-to-win slots like this one. Before depositing anywhere, it’s worth running through our guide on how to choose a safe online casino so you know what licensing and payout track record to look for.

If you’re comparing options, our best casinos list is a good starting point, and operators such as NeedForSpin, 7Bit Casino, Vave and BitKingz all carry a solid Microgaming slot library alongside crypto deposit options. For sportsbook-and-casino combos, Betwinner is also worth a look.

Most of these sites run some form of welcome bonus or free spins offer that can be put straight to use on Avalon II, and some operators still offer no-deposit bonuses for new players who want to test the Grail Bonus without risking their own funds first. If you play regularly, it’s also worth checking which sites offer a cashback bonus, since medium-volatility slots like this one can produce longer losing streaks between big bonus triggers.

Whatever bonus you claim, read the terms before you spin — our wagering requirements explained guide breaks down how playthrough, max bet limits and game weighting actually work, which matters more on a feature-heavy slot like Avalon II than on simpler titles.

Funding Your Account

Deposit speed and fees can make a real difference to how much of your bankroll actually reaches the reels. Most Microgaming casinos support a broad spread of payment methods, from traditional cards to crypto. Crypto players typically have the widest choice, with Bitcoin, Ethereum and USDT all commonly accepted and usually processed faster than bank-linked methods, particularly for withdrawals. For players who prefer conventional banking, Visa and Mastercard remain the most universally supported options, while e-wallets such as Skrill and PayPal (where available) can offer a useful middle ground of speed and widespread casino support.

Our Verdict

Avalon II earns its reputation as a Microgaming classic on the strength of its bonus feature alone. The eight-level Grail Bonus gives the game a sense of progression and variety that most 243-ways slots from the same generation simply don’t have, and the medium volatility keeps sessions playable without the feeling that you’re grinding through dead spins waiting for one big swing. It’s not the flashiest slot on the market in 2026, and the base game by itself is relatively ordinary, but as a complete package — theme, structure and bonus depth combined — it’s aged better than most of its contemporaries and remains a sensible pick for players who like a slower-building, feature-rich session rather than a high-variance, all-or-nothing spin.
