Editorial note: this is a general guide to how Avalon II works. Slot rules, feature availability and RTP can vary between operators and game versions, so always check the in-game information panel before you spin. Slots are games of chance — nothing here is a prediction of results, and no strategy changes the odds.
Avalon II slot review
Avalon II — The Quest for the Grail — is Microgaming’s 2014 Arthurian epic and one of the most ambitious slots ever attempted: a five-reel, 243-ways adventure in which the bonus is not a round but a journey, advancing through eight different Grail-quest stages the more often you trigger it. Veterans still speak of it with reverence: at launch its production values — voice acting, cinematics, an orchestral score — simply had no peers, and a decade of imitators never quite recaptured the sense of occasion.
How Avalon II plays
Arthur, Guinevere, Merlin and the Black Knight command the paytable across 243 ways, where matching symbols on adjacent reels from the left pay in any position. The Lady of the Lake acts as the wild with her own multiplying moments, and Merlin can interrupt base play at random with multiplied wins or cash awards — a wizardly nudge between quest stages.
The eight-stage Grail quest
Three Grail scatters begin the quest, and each trigger advances you to the next chapter: free spins by the Lake of Legend, dice rolls through the Misty Vale, the Whispering Woods shield picks, the Morgan’s Keep duel and more, culminating at the Isle of Avalon’s wheel-within-a-wheel finale. No two visits play alike until the cycle completes, and the structure — a bonus that remembers your progress — directly prefigured the unlockable systems of Immortal Romance and Thunderstruck II.
RTP, volatility and top wins
The commonly published RTP is just under 96%, with operator versions varying — the in-game information panel shows the live figure. Volatility is medium-high, with the later quest stages carrying the heavier prizes and advertised top wins of several thousand times stake awaiting at journey’s end.
