Avalon Slot Review
Avalon is one of Microgaming's most enduring slots, first released in 2006 and still drawing players two decades later. Based on the legend of King Arthur and the mystical island where the king was taken to heal after his final battle, it offers 5 reels, 20 paylines, a 97% RTP and a free spins round that can multiply your wins up to 7x. If you enjoy Arthurian mythology wrapped around a classic video slot format, Avalon is worth your time.
Theme and Symbols
The game places you in a misty, candlelit world of medieval courts and ancient magic. The reels sit against a backdrop of stone archways and amber torchlight, with a restrained orchestral score that fits the setting without becoming irritating over long sessions.
Symbol quality ranges from the expected - playing cards given a regal treatment in gold and jewel tones - up to original Arthurian artwork: an emerald brooch, a coat of arms, a jewelled goblet and a treasure chest. High-value symbols depict King Arthur himself, the wizard Merlin, Guinevere, Morgan le Fay and the Black Knight. The art style is detailed for its era and still holds up reasonably well on modern screens.
The Avalon logo acts as the main wild symbol, substituting for all standard symbols. Five wilds across an active payline pay the top jackpot of 3,000 coins. The Lady of the Lake is the scatter - land two or more anywhere on the reels for a scatter pay, and three or more to trigger the free spins feature.
RTP and Volatility
Avalon carries a 97% RTP, which sits well above the industry average of around 95-96%. That figure means the game returns more to players over time than most of its peers, which is part of why it has stayed popular for so long. Volatility is medium, so you can expect a reasonable spread of smaller wins keeping your balance ticking over alongside the occasional larger hit from the free spins multiplier.
Stakes run from £0.01 per line up to £100 per spin, covering casual play through to higher-limit sessions.
Free Spins Feature
The free spins round is where Avalon earns its reputation. Land three or more Lady of the Lake scatter symbols anywhere on the reels and you receive 12 free spins. During those spins, a random multiplier applies to every win - it can land anywhere from 2x up to 7x and is displayed above the reels throughout the round.
The treasure chest symbol, which is a standard paying symbol in the base game, turns wild during free spins. That gives you two wild symbols active at once - the Avalon logo and the treasure chest - which noticeably increases the frequency of winning combinations across the 20 paylines.
Free spins can be re-triggered during the feature by landing three more scatter symbols. This is one of the more generous re-trigger mechanics of slots from this generation - there is no cap on the number of times the feature can be extended.
Gamble Feature
After any base-game win, you can choose to gamble rather than collect. The gamble screen presents a face-down playing card. Guess the colour correctly to double your win; guess the suit correctly to quadruple it. Guess wrong and you lose the win entirely. The gamble feature is entirely optional and can be ignored if you prefer to bank wins as they come.
It is a straightforward risk/reward mechanic - useful for small wins you want to push higher, less advisable when gambling a significant payout. Most experienced players use it selectively rather than routinely.
Autoplay and Controls
The control panel sits along the bottom of the screen in a clean, uncluttered layout. Standard mode keeps controls minimal - spin, bet adjustment and paytable access. Expert mode adds autoplay, letting you set between 5 and 500 automatic spins. There are no stop-on-win conditions or loss limits built into the autoplay beyond the basic spin count, which is typical for a game of this age.
Avalon is available on both desktop and mobile. Microgaming updated the mobile version with HD graphics and improved audio, and it runs smoothly on modern smartphones and tablets via browser without any download required.
Avalon vs Avalon II
Avalon II: Quest for the Grail arrived in 2014 as a substantially expanded sequel. Where the original Avalon keeps things focused - one bonus feature, clean mechanics - Avalon II is a feature-heavy game with eight separate bonus rounds, each tied to a chapter of the Arthurian quest. The sequel is longer, more complex and more volatile. The original remains the better pick if you want a steady, reliable session; Avalon II is the right choice if you want a more involved narrative experience. You can find the full breakdown in our Avalon II review.
Final Verdict
Avalon has remained relevant for nearly 20 years for good reason. A 97% RTP, a free spins round with a 7x multiplier ceiling, two active wilds during bonus play and re-triggerable spins give it more substance than many of its contemporaries. The Arthurian theme is handled with enough craft that it still feels coherent rather than dated. If you have not played it, it deserves a session. If you played it years ago, it holds up.
