Avalon slot

Avalon is the slot I hand new players when they want to see what a genuine “classic” Microgaming machine plays like.

It’s a 2006 release, now sitting under the Games Global banner after Microgaming’s corporate rebrand. There’s no cluster mechanic here and no ways-to-win math — just 20 fixed paylines running straight across five reels. I loaded up the demo expecting a museum piece and ended up staying longer than planned. The base game runs quiet for long stretches until the Lady of the Lake scatter finally lines up across the reels, and that’s when the whole pace of a session shifts hard in your favor. Medium volatility delivers genuine payout bursts separated by real dry spells.

Avalon runs on a standard 5×3 grid with 20 fixed paylines. Every line pays left to right on three or more matching symbols, and there’s no way to switch lines off; you’re betting on every payline or you’re not playing.

The theme sits on the more restrained end of Arthurian legend. Instead of clashing swords and dragons wall to wall, you get Merlin-adjacent iconography, misty lake visuals, and an Excalibur-styled sword symbol doing most of the work on the paytable. The betting range runs roughly $0.20 to $50 a spin, though the exact floor and ceiling shift slightly depending on which casino you’re playing at. Land three, four, or five Lady of the Lake scatters anywhere on the grid and the free spins round kicks in. Position doesn’t matter here, which takes some pressure off chasing specific reel patterns the way pattern-based games demand.

Base-game wins lean on the sword wild doing what wilds do. It stands in for every regular symbol on an active line. It won’t cover the scatter, so don’t count on it bailing out a near-miss. The overall rhythm is slower and more deliberate than a lot of newer Microgaming releases, which tracks, given it’s pushing two decades old now.

Wilds & the Treasure Chest

The base wild is the sword symbol. It substitutes for every symbol except the scatter, the same job most Microgaming wilds from this era were built to do.

The Treasure Chest wild only shows up once you’re inside the free spins round, and it substitutes the same way the sword wild does, but its appearance is really a signal that the free spins math has taken over from the base game.

Free Spins

Hit three, four, or five Lady of the Lake scatters and you’re awarded 12 free spins. There’s no retrigger built into the round, so whatever you land at the start is what you play out.

The spin count isn’t the number that matters here. It’s the multiplier. Every single win during those 12 spins gets multiplied by 7x, flat, across the board, and that’s meaningfully higher than a lot of comparable Microgaming free-spin rounds ran back in the mid-2000s. It’s the reason Avalon’s free spins round can swing a whole session even though the round itself is short. Twelve spins goes fast. A flat 7x on each one goes further than the spin count alone suggests it should.

Gamble Feature

Win a spin and Avalon offers a gamble round. Guess the color of a face-down card. Guess right and the win doubles. There’s also a suit guess available that quadruples it, at real risk of losing the win outright if you guess wrong.

You can switch the gamble feature off entirely, at any point. Some classic Microgaming gamble rounds lock you in once triggered. This one doesn’t, and that’s a small design choice I appreciate more than I expected to. That single toggle keeps the whole thing a purely optional flutter, there for players chasing an extra bit of risk after a win and easy to skip for everyone else.

Avalon’s official RTP sits at 96.01%, which is decent without being exceptional for a vintage Microgaming title. Medium volatility describes the middle ground between the two extremes. You won’t hit the long featureless dry spells that high-volatility slots are known for, but you also won’t see splashy short-burst payouts landing every few spins either.

The payout structure rewards patience over speed. The paytable can pay out well beyond four figures on a strong combination, particularly once the 7x free spins multiplier stacks on top of a decent base hit. Published max-win figures for this game vary a fair bit depending on which paytable version and operator you check, so treat any single number you see quoted elsewhere with some skepticism. The RTP itself is fixed and publicly audited, and it doesn’t change no matter which casino is running the game.

Avalon runs on HTML5, so it loads straight into a mobile browser with no app download required.

I tested it on a phone screen, and the paytable text stayed readable without excessive pinching and zooming, which isn’t a given on a game built back when tablets barely existed. The free demo on this page runs the exact same math as the real-money version. The RTP, the payline count, and the free spins multiplier are identical to the real-money game. If you’ve never played a classic fixed-payline Microgaming slot before, run the demo first. It’s a fast, no-risk way to learn the scatter-trigger pattern before any real money is on the table.

If Avalon’s pace suits you, Avalon II – Quest for the Grail is the obvious next stop. It’s the direct sequel, built on a more modern engine, and it keeps the Arthurian theme while adding mechanics Microgaming simply didn’t have on the table when the original was released.

For something from the same studio family but with a completely different structure, Thunderstruck 2 swaps the Round Table for Norse mythology and runs four separate bonus rounds tied to four different gods. It plays faster and hits harder than Avalon. Both are worth a spin if the original left you wanting more mechanics wrapped around a similar legend-driven theme.

You don’t need to hunt around for Avalon. Most established online casinos carrying the Microgaming or Games Global library run it, and the operators listed on this page have been checked for live availability of this exact title.

Bet limits and any welcome offers tied to a specific operator will vary, so it’s worth comparing what’s on the table before committing a deposit anywhere. What stays constant no matter where you play is the game math itself. The RTP, the payline structure, and the free spins multiplier don’t shift from casino to casino. Pick a licensed operator you trust, then let the game do what it does.

Avalon holds up. It’s not flashy, it doesn’t chase modern slot trends, and it clearly wasn’t built with today’s expectations in mind, but the fixed-payline structure and the flat 7x free spins multiplier still give it real teeth almost two decades later.

Play it if you want a slower, more deliberate session and don’t mind medium volatility testing your patience between scatter triggers. Skip it if you’re chasing high-volatility swings or bonus rounds that reset every few seconds. For what it is, and for when it was built, Avalon still earns its spot on a lot of casino lobbies.
