In this tournament, we must try to lose our games by scoring in our own nets (Strikers Charged) or getting negative points (Sports Mix). Negative points can only be gained in Bowser Jr. Boulevard (also known as Bowser Jr. Blvd) in hockey and basketball by standing on a negative (red) circle. I haven't found a way for Petey to score in his own net by himself in Strikers, so Petey users might have a disadvantage. Sign ups are unlimited and sorted by country due to the region lock.
