I'm glad I logged on last night - I was able to participate in the first set of challenges. The new setup has me a little bit unsure - I love the added challenge of trying to track down the games... but at the same time I know I'll be pulling my hair out.
Edited to add:
Here is what you need to beat the first set of challenges:
Secret Game: 150+ in Meerca Chase. Theme Games: Itchy Invasion (125) and Cooty Wars (150).
Matrinka, please check out the thread in General Chat about the Games Master Challenges We have a listing of everything you need to do as well as the prizes.
