Avalon 3: Slot Overview
Cast your mind back to 2006, when software provider Microgaming launched the Arthurian Legend-themed slot Avalon, a title that quickly earned a comfortable place in plenty of players’ favourites lists. Eight years on, Avalon 2 arrived, and more than a decade after that we finally got Avalon 3. Since the first game debuted, the creator has rebranded and handed development of the third instalment to its partner Stormcraft Studios, which has packed the slot with elements like Magic Orb prizes, Jackpots, and free spins.
The action unfolds in a gothic hall of arches, pillars, and treasure. Coins are scattered across the floor, while a regal figure—likely Arthur—watches over the wealth. The interface makes the key mechanics hard to miss, with a free spins panel and a Magic Orb chest positioned above the reels, and Jackpot values shown at the side to help players quickly judge whether the game suits them. The presentation is far sharper than the original, as you’d expect after so many years, and the music is suitably dramatic.

Using a highly volatile math model, Avalon 3 runs on a 5×4 grid and uses 20 paylines to evaluate winning results. Tap the coin icon to access the bet settings, where stakes range from 20 c or as high as $/€50 per spin. Of the three RTP setups, the best available is 96.3%, and at that setting the theoretical hit rate is 18.11%.
Avalon 3’s symbol ladder includes 9-A royals, a room, some scenery, a castle, a throne, a dragon sculpture holding an orb, and Merlin. Five-of-a-kind royals return 1x to 1.8x the bet, while the other symbols pay 2x to 10x the bet for a 5 OAK line-up. Wild symbols replace any standard paying symbol and can appear stacked in both the base game and free spins.
Avalon 3: Slot Features

Watch for Orbs, because they tie directly into the main mechanics, including a Magic Orb Bonus, a Jackpot Bonus, free spins, and a bonus buy option.
Magic Orb Bonus
Magic Orb symbols appear on the middle reel. Each time a Magic Orb lands, the Magic Orb Count (which begins at 5) increases by +1, up to a maximum of 50. The Magic Orb Bonus can randomly trigger when a Magic Orb is collected. Before the next spin, a number of prizes equal to the Magic Orb Count is placed onto the reels. These prizes can include the Mini, Minor, or Midi Jackpots, along with Coin values of up to 6x the bet. A Magic Orb Multiplier of x2 or x3 may randomly boost all prizes awarded, and once prizes are paid, the Magic Orb Count resets to 5.
Ways Wins
If 3 or more Magic Orbs land on consecutive reels starting from the leftmost reel and no feature activates, a Ways Win pays out Orb prizes. Free Spins and Jackpot Orbs function as wilds, making it easier to form Ways Wins.
Jackpot Bonus
Collecting Jackpot Orbs on reels 2, 3, or 4 increases the Mega or the Maxi Jackpots. Picking up Jackpot Orbs may also randomly trigger the Jackpot Bonus. When it starts, players click coins until 3 matching Jackpot symbols appear, and that matching reward is awarded. Available prizes include the 8x Mini, 15x Minor, 40x Midi, 100x to 1,000x Maxi, or the 1,000x to 5,000x Mega. An x3 multiplier can be added to the Midi, Minor, and Mini win.
Free Spins
Collecting free spins Orbs on reels 2, 3, or 4 can randomly trigger the free spins feature. It kicks off with 8 free spins and a Magic Orb Count of 5. In free spins, if the Magic Orb Bonus activates, the Magic Orb Count remains persistent for the entire round. Hitting a Free SPins Orb adds +3 free spins.
Bonus Buy
Avalon 3 allows players to purchase its free spins feature, and the price is 100 times the bet.

Avalon 3: Slot Verdict
By online casino standards, the original Avalon is practically from another era, and that may explain why—despite nearly twenty years passing—Avalon 3 can also come across as a touch dated. It doesn’t help that the design leans heavily on local Jackpot mechanics, a style that keeps pouring out of the Games Global network of studios. Enough players must be enjoying it to justify the constant return of features like the escalating jackpot values. Some clearly prefer the concept of building jackpots up to their peak rather than having the top prize available from spin one. Either way, the GG crew has found its lane and continues to fill it with releases like Avalon 3.
Alongside the Jackpots sits the Magic Orb Bonus, which at least adds some variety. It can deliver payouts in the base game, and the animation of Orbs drifting into chests and back onto the reels adds a bit of spectacle. The Magic Orb Bonus becomes more engaging during free spins because the Magic Orb Count doesn’t reset while the feature is running, and the Magic Orb Multiplier also comes into play. That said, there are noticeably fewer features than Avalon 2 offered, which may disappoint fans of the previous entry; the win potential is also lower, topping out at 5,000x the bet.
So, Avalon 3 ended up feeling somewhat underwhelming, though that’s not entirely unexpected given this collection of studios’ dependence on local Jackpots. It may still appeal to long-time players chasing a bit of nostalgia, and there’s a certain curiosity factor in a third instalment of such a long-running series. But without the familiar name and history behind it, Avalon 3 might not have attracted much attention at all.
