At this place you can spend Adventure Tickets, that were obtained while meditating in Yggdrasil, to do one of the Adventures.

In the game each "egg" contains one of the silver values displayed on the sides.
Once the game starts, you choose one of those eggs and place it on the side.
Then you have to eliminate 6 of those eggs.
