Overview System Requirements


Let’s get into mischief! It all begins when Wendy decides to throw an end-of-year party at home with her friends. Before she gets a chance to ask her parents, her unbearable little sister Maureen steals her idea and asks their parents first. Unfortunately, the parents will allow only one party! Maureen and Wendy start a series of crazy challenges to decide which one of them will host the party. With sister against sister, there is going to be trouble!

  • - All or Nothing: play all the mini-games one by one!
  • - Around the World: take turns choosing your favorite mini-game!
  • There are 24 crazy mini-games, which come straight out of the Sisters’ imagination, such as unicorn toss, cupcake factory and extreme ping-pong.
