Divide the group into two teams
Divide the property into two sides(such as front and back yard)
Designate a “jail” area for each team. The jail area also holds the flag.
Players can be caught by the other team if they are tagged while they are in the other team’s territory. If a player is caught, they must go to the other team’s jail and can only be released if a teammate tags them while they are in jail.
If a player captures the flag and brings it back to their own side without being tagged wins!
