About the game

Avalon II: Quest for The Grail is Microgaming's 2014 sequel to the 2006 Avalon slot. Where the original was a conventional 20-payline video slot, Avalon II expands to 243 ways to win across 5 reels and adds the eight-stage Grail bonus — a progressive structure where players unlock different bonus rounds tied to characters from the King Arthur legend.

The Grail bonus unlocks sequentially. The first stage is The Misty Vale, a 25-spin round with rolling reels. Subsequent stages — The Whispering Woods, The Forest Falls, The Dusky Moors, Morgan's Keep, The Black Knight, Lake of Legend, and finally the Isle of Avalon — each have distinct mechanics: stacked wilds, multipliers, sticky wilds, re-spins. Players must complete each in order. Reaching the Isle of Avalon and triggering its bonus is the design's long-tail hook.

Frequently asked questions

What is the RTP of Avalon II?
95.92% — slightly below the iGO Ontario industry average but in line with Microgaming-era 243-ways slots from this period.
How does the Grail bonus work?
The Grail bonus unlocks across eight progressive stages tied to characters from the King Arthur legend. Players start at stage one (Misty Vale) and unlock the next stage by triggering and completing the current one. Each stage has different mechanics — rolling reels, stacked wilds, multipliers, sticky wilds. Reaching the eighth stage (Isle of Avalon) is the long-term goal.
Is Avalon II the same as the original Avalon?
No — they are separate games. Avalon (2006) is a 20-line, 5×3 video slot with a single free-spins round. Avalon II (2014) is the sequel: 243 ways to win and the eight-stage Grail bonus. Both are in Ontario operator catalogs but Avalon II is the more popular of the two.
Is this slot legal to play in Ontario?
Yes — provided you play at an iGaming Ontario / AGCO-licensed operator. The casinos listed above are Ontario-licensed. Playing on unregulated international sites from within Ontario is not legal and offers no consumer protections.
