Avalon slot

Avalon slot machine at a glance

Avalon takes its name from the island of Arthurian legend, where the sword Excalibur was forged and the Lady of the Lake lives. Microgaming launched it in 2006, two years after Thunderstruck, and it belongs to the same generation of straightforward five-reel video slot machines: fixed lines, a wild, a scatter and a free spins round.

The game now sits with Games Global, the Isle of Man company that took over Microgaming's games portfolio and distribution business in 2022. That's why you'll see both names attached to it. For other titles we cover, start at our slot games hub.

How the Avalon slot works on 20 paylines

A payline is a fixed path across the reels, one position per reel. Avalon checks 20 of them every spin. A line pays when the same symbol appears on consecutive reels from the left, starting on reel 1. Only the highest win on each line is paid, and wins on different lines are added together.

1. Set your total stake. The game divides it across the 20 lines, so a 20p total is a 1p line bet.
2. Press spin. The random number generator chooses where each reel stops.
3. The game reads all 20 lines and pays any that start with a matching run on reel 1.
4. Scatter symbols are counted separately, wherever they land.
5. Wins are added to your balance; three or more scatters start the bonus.

Worked example: line bet and total bet

At a 40p total bet, each line carries 2p. If a symbol's paytable value for three of a kind is 10 times the line bet, a three-symbol win on one line pays 20p, and two such lines pay 40p, which is exactly your stake back. Under UK rules, a result like that must not be celebrated as a win. The paytable values here are illustrative; open the game's paytable for the real ones at your stake.

Avalon symbols and paytable

The reels mix playing-card royals (the low-pay symbols) with Arthurian picture symbols, which fill the higher tiers. The Lady of the Lake acts as the wild, standing in for regular symbols to complete lines. A treasure chest is the scatter that pays anywhere on the reels and starts the bonus.

The help screen sets out exactly which symbols the wild can replace, whether it multiplies wins it helps form, and what each symbol pays for three, four and five of a kind. Because the game has been reissued and tuned since 2006, read the version in front of you rather than trusting an old description.

Avalon free spins and bonus round

Landing three or more treasure-chest scatters starts the free spins round. During it, wins are boosted by a multiplier, which is where the game's largest results usually come from. The help screen states the number of spins, the multiplier and whether the round can be retriggered.

With medium volatility, the bonus carries a meaningful share of the return but the base game also pays its way more often than on modern high-volatility titles. That balance is the main reason older games like Avalon still appeal to players who want a steadier session. How often the round triggers isn't published in any source we hold, so we don't estimate it; what triggers a bonus round? explains why trigger odds are rarely disclosed.

Avalon RTP and medium volatility explained

At 96.01% RTP, the long-run average cost is just under 4p in every pound staked. That figure is an average across millions of spins, not a promise for a session. Medium volatility means results bunch less dramatically than on a high-volatility game, but you can still lose your whole budget. Our page on medium-volatility slot machines explains the trade-off, and RTP explained covers how the figure is calculated.

The Gambling Commission's rules on game descriptions and the likelihood of winning (opens in a new tab) require the RTP to be available to players, so you'll find it in the game rules at any UK-licensed casino.

Avalon max win and UK stake limits

We don't hold a verified maximum win for Avalon, so we don't quote one. Open the help screen, where the top prize is stated either as a multiple of the stake or in pounds at your current stake. To translate any multiple into money, multiply it by your total stake. The table shows how two example multiples convert at stakes allowed in Great Britain.

The stake caps come from the Commission's online slots stake limit guidance (opens in a new tab): £5 per spin for players aged 25 and over since 9 April 2025, and £2 for 18 to 24-year-olds since 21 May 2025. Our max win glossary entry explains how ceilings are written.

Is the Avalon slot worth playing in 2026's lobbies?

Newer isn't automatically better. Modern games often trade more frequent small wins for a bigger ceiling, and our answer to are new slots better than old ones? explains why. Avalon suits adults who want a simple, lower-drama game and are happy with a modest prize range.

Slots like Avalon

• Thunderstruck: Microgaming's 2004 Norse game on 5×3 with 9 lines and medium volatility, the closest relative in age and style.
• Rise of Merlin: Play'n GO's Arthurian-themed 5×3 game with 10 lines, but high volatility.
• Immortal Romance: a later Games Global classic using 243 ways rather than lines.

Microgaming also produced a sequel, Avalon II, which reworked the theme with a more elaborate bonus; it is a separate game with its own maths, so don't assume its figures apply here.

Avalon myths: what an old slot does and doesn't do

• 'Older slots pay more because casinos forgot to change them.' RTP settings are chosen by the operator and tested; age doesn't loosen a game.
• 'Playing all lines raises the RTP.' Lines are fixed at 20, and the RTP is a property of the whole game.
• 'The Lady of the Lake appears more after a losing streak.' Each spin is independent; see the gambler's fallacy on slots.
• 'You can time the spin button.' The result is set when you press spin, and pressing again can't stop the reels early online.

Finding the Avalon RTP and rules in the help screen

1. Load the game and open the menu (often three lines or a question mark).
2. Choose 'Paytable' to see symbol values at your current stake.
3. Choose 'Game rules' or 'Help' to find the RTP, the free spins rules and the maximum win.
4. If the RTP shown is below 96.01%, the casino runs a lower setting; compare elsewhere if that matters to you.

How UK rules changed the Avalon slot machine

Avalon predates the Gambling Commission's 2021 design rules, so UK versions were updated. Since 31 October 2021 the responsible product design standard (opens in a new tab) has required no autoplay, no turbo or quick-spin, a game cycle of at least 2.5 seconds, a clear net position on screen, and no celebration of returns equal to or below the stake. Our spin speed rule page explains how the 2.5 seconds is measured.

Demo play is available only after age verification, in line with rules from May 2019, and credit cards can't be used to fund play. See UK slot machine rules for the full list.

Where to play the Avalon slot online

Classic Games Global titles are widely supplied, but no casino is obliged to carry any one game, so search the casino's lobby; game availability changes. New customers aged 18+ can look at three offers here, all with terms. Coral: deposit and bet £10 on slots, then get 100 free spins at 10p each on selected games (accept within 48 hours, valid 7 days, no wagering on winnings). Ladbrokes: play £10 on slots for 50 free spins a day over your first 10 days, up to 500 at 10p each, claimed by 23:59 daily, with no wagering.

Offer spins are tied to selected games, which may not include Avalon, and some payment methods are excluded. Gambling costs money, so set a limit before you start. If you need to block gambling sites, GAMSTOP (opens in a new tab) covers every UK-licensed operator.
