Searching for a specific guild

Guild leaders have the ability to manage guild members

Members of the guild are visible via scroll list.

Guilds have a weekly "Bike Race" competition to encourage social play.  Launch screen gives a quick description on how the game is played.

User chooses from three different tasks.  Each task has a different prize level based on difficulty.

Once a task is chosen, the user is able to start fulfilling the task.  In this case, deliver 15 hotdogs.

As points are earned via tasks by guild members, the "cyclist" advances further down the track.  As the cyclist passes prize markers, more prizes are won.  The cyclist represents the user's entire guild.

This screen shows how your guild members are progressing in the event.
