The Fortress of Activity Play System links seven of our most popular activity panels into one semi-enclosed shape. Each panel offers its own unique way to play which can be used from either the outside or inside of the structure (and sometimes both sides at the same time, as in the percussion panel). Some of the panels encourage community and developing friendships with two-person activities, such as the Tic Tac Toe panel, where children can play oversized games of tic tac toe; or the Store Panel, which contains a window and counter that kids can use to create any imaginary scenario they can devise on their own. Other panels offer activities for a child to complete independently. The ‘C’ shape means that kids can stand in the middle to experience every activity at once while enjoying a relative degree of privacy. The Fortress of Activity offers enough diversions to ensure that every kid, regardless of their level of physical ability, will find something to enjoy, even on the most crowded playgrounds.
