A virtual activity space is provided to users. The virtual activity space, or instances of the virtual activity space, may be used to enable users to participate in an activity such as, e.g., a card game. A user may participate in multiple activities concurrently. One of these activities, the so-called primary activity, is more dominantly and/or prominently presented than the other activities, the so-called secondary activities. Navigating between concurrent activities is accomplished through an interface that is displayed at the periphery of a view of a virtual activity space. A selection of a secondary activity simultaneously causes the primary activity to become a secondary activity, and causes the selected activity to become the new and current primary activity.
