Make a Team Up announcement for Housing Games, like Winterbane Hall, Midnight Sun Pagoda, Spiral Cup Gauntlet, etc....etc...etc.
We have a Team Up near by the Bazaar but the Housing Games are not available there, . Make them available perhaps by adding your House game to the Castle Tour.
A Castle Tour to join your Castle. A Team Tour to join the Housing Games, which you make available or Remove at anytime you want, so that people can join the game all over Wizard101.
