Split the group into two even teams and assign them half of a playing area each (can use the centre line if played on a court OR create boundaries with cones). You will need props that will act as a "wall" (high jump mat, blow up bunkers etc) that will run down the centre line, blocking out visability. One team will lay down on their side (within a defined area, once set in position they may not change location) whilst the other team will stand at the back of their side preparing to fire their arrows over the wall to hit players on the opposing team. 

RULES: 

- Players shooting arrows may not move to the side so that they can see past the wall and spot players from the opposing team
- One player will shoot their arrow at a time (maximum of 3 arrows each which will result in three rounds for each team)

POINTS SYSTEM:

- A player will be awarded two points if they manage to hit the opposition on the full
- A player will be awarded one point if they manage to hit the opposition after their arrow has hit the ground and bounces
- If a player moves out of the way before an arrow hits them, the team firing the arrows will be awarded one point

ELIMINATION SYSTEM:

- Each player from a team will have three arrows with the objective of trying to eliminate as many players from the opposing team. If someone is hit, they will stand up and move to the side of the playing area. Once all arrows have been shot, count up any players that still remain and swap roles. Which ever team has the most amount of players left, will be declared winners UNLESS a team gets completely eliminated.
E.g. Team B = 5 players remaining, Team A = 2 players remaining...Team B win.
