Mine Field Mine Field is a teambuilding activity involving trust and teamwork. What do you Need We play Mine Field on the L'Abri soccer field. We need at least 4-10 players on each opposite side of the field. North, South, East and West. We use colored balls as the "life threatening mines".

He or she must safely avoid touching the “mines,” by carefully listening to the verbal guidance of their team members.
