Game Rules Guide

The village needs a Main Building at level 10 or higher and cannot already have another demolition in progress. A completed ordinary building or flexible resource field is eligible, including the Main Building itself; the 4 fixed resource fields, the World Wonder, and a building under upgrade cannot be demolished, and an upgrade cannot start on a slot being demolished. One task razes the whole building whatever its level and takes a fixed 5 minutes on every server regardless of speed. You can cancel before the timer ends and leave the building untouched. On completion, the building is removed and the slot becomes empty; rebuilding the Main Building starts normally from level 1.
