Embark on the Holy Grail Quest — adventure awaits
Some games are more than just slots — they're a complete experience. Avalon II: The Quest for the Holy Grail is exactly that. Developed by Microgaming in 2014, it turned heads from day one. The reason is simple: this many bonus features, this much story depth, and this high an RTP in a single slot is genuinely rare.
King Arthur's Camelot, the wizard Merlin, the enigmatic Morgan Le Fay, and the sacred Holy Grail — the most iconic legends of English literature come alive in this game. The moment you launch Avalon II at bddd, it feels like standing inside a medieval castle, with the atmospheric soundtrack, the sound of crickets, and the glow of torchlight creating a world entirely its own.
This game's RTP at bddd is 97.02% — exceptionally high by slots standards. That means for every 100 BDT wagered, an average of 97 BDT is returned. Over the long term, this works in the player's favor.
This game goes far beyond a single bonus feature — it comes with 8 distinct Quest bonus modes. Each mode offers a different number of free spins, its own multipliers, and unique special features. It's essentially eight games in one.

The most exciting part of the free spins bonus
Rolling Reels is one of Avalon II's most powerful features. During a bonus round, when a winning combination lands, those symbols disappear and new ones drop in from above. If the new symbols also form a win, they vanish too — letting you chain multiple wins from a single spin.
Consecutive rolls in the same spin keep building the multiplier. Depending on your Quest mode, it can reach 2x, 3x, 5x, 6x, 8x, or even 10x. When playing Avalon II at bddd, you can hit moments where Rolling Reels triggers 6 or 7 times in a row — and when that happens, the payout is genuinely jaw-dropping.

The tale of King Arthur and his Knights of the Round Table is one of the most influential legends in Western civilization. The quest for the Holy Grail, the mystery of Excalibur, the magic of Merlin, and the mystique of the isle of Avalon — these elements have appeared time and again in film, games, and literature. Microgaming has brought this entire legend to life in a slot game so compellingly that playing it genuinely feels like being part of the quest yourself.
The music that plays the moment you open Avalon II at bddd captures the atmosphere perfectly. Slow, sweeping orchestral scores and medieval visuals make this more than just a game — it's an immersion into a story.
RTP stands for Return to Player — in this game, for every ৳100 wagered, an average of ৳97 is returned. Keep in mind, this is an average across millions of spins and can vary within a single session. Over the long run, a 97% RTP means a house edge of just 3% — which is exceptionally favorable in the world of slots. Compared to other slots at bddd, Avalon II offers one of the highest RTPs available.
The short answer — Quest VIII. But reaching it takes time. In real gameplay, Quest III (Merlin) and Quest VII (Siege of Benwick) also deliver big payouts because the Rolling Reels multiplier builds quickly.
Bddd tracks your Quest progress across every session — so if you left off at Quest V, you pick up right where you were next time. This continuity means your progress is never lost.
Both are among Microgaming's finest slots, and both are available at bddd. Thunderstruck II brings Nordic gods, the Wildstorm feature, and 4 bonus modes. Avalon II dives into Arthurian legend with 8 Quest modes, a higher RTP (97.02% vs 96.65%), and Rolling Reels. If you want more bonus variety and a long-form Quest experience, Avalon II is your game. For fast-paced thrills and Wildstorm action, go with Thunderstruck II.
A few things to keep in mind for success in Avalon II. First, set a loss limit — decide how much you're willing to lose before you start, and stick to it. Second, cash out a portion of your winnings — don't put your entire balance back into play; set some aside. Third, use Autoplay — it helps curb the impulse to raise your bet in the heat of the moment. All these tools are available in your account settings at bddd. Learn more: Responsible Gaming
