Anytime you hit 3 or more of the Grail symbols anywhere on the reels, you will embark on a quest through the Kingdom to retrieve the Holy Grail and return the relic to the island Avalon.
There are 8 different bonus moods:
Lake of Legend Bonus feature
This is a simple dice roll bonus game where your job is to reforging the fragments of Excalibur. Throwing the dice, you will get a number that is associated with a sword fragment of a certain shape. If there is a match, the fragment will move into the reforge desplay, and the number you get is equal to the multiplier paid out.
Misty Value Bonus feature
Here you get to choose one of the high value symbols to act like an extra wild for the entire duration of the 15 free spins. This extra wild has a x2 multiplier.
Whispering Woods Bonus feature
Pick 1 out of 5 options and cross your fingers, hoping to get the highest multiplier possible (a x160 multiplication of your bet).
Forest Falls Bonus feature
This means 20 free spins, and an Avalon II wild. Anytime one of these are landen on row 1 or 2 of any reel, it will hold in place but also expand downwards; then it will be locked to the same position for the next spin as well.
