Training Center Collectibles

Hello to everyone, I just got the game and I’m really enjoying it!
I was wondering what do you have To collect in the training center apart the course maps?

Thank you

 

Only maps there normally. There is a mastery thing for easter where you collect eggs also.

 

Can anybody explaing how I can collect the easter eggs?
I don't see any of them.

Apparently you need to unlock a Mastery layer of some sort, but I don't find that anywhere either?

 

Please correct me if I'm wrong, but I remember reading that the Easter Mastery is only activated at Easter. As soon as you have collected at least one egg, you can switch the overlay on and off for the whole year. So if you have never collected an egg you will have to wait until Easter.

Here are some infos about the Easter events of 2023 and 2024, it indeed seems to be a time limited event at Easter time.
