Capture the Flag is a favourite game to play outdoors.
There are two teams. Team 1 has the front yard, and Team 2 has the back yard, or a field is split between the two teams. The teams are given a time period (e.g. 5 minutes) to hide their flag in their part of the yard.
[optional] During this period, spies were sent out to see where the flag was hidden and look-outs to catch the spies.
When the flag is hidden, you call out that you are finished. Then you simply try to get the other team’s flag. If you get caught and tagged by the opponent on their territory, you have to go to jail and can only be freed by a teammate who grabs you when your opponent isn’t looking.
The first team to capture the flag wins. In most versions, you had to both get the flag and bring it back to your side.
