Capture the Flag: Rules, Field Setup and Fair Teams

Capture the flag is an outdoor team game for a big group: two teams each guard a flag in their own half of the field, and try to sneak into the other half, grab the enemy flag and carry it home without being tagged. It mixes running, tagging and a bit of planning, and it works for scout groups, PE lessons, camps and family parties. Here are the rules, how to set up the field, a fair way to split the teams, and some popular variations.

What you need

• A large open space, such as a field, a park or a playground, with a clear middle line.
• Two flags: bandanas, scarves, cones or T-shirts all work.
• Something to mark each team’s jail, such as cones, a hoop or a chalk circle.
• Team markers so everyone can tell the sides apart: coloured bibs, armbands or two colours of T-shirt.
• At least eight players; ten to thirty is ideal.

Setting up the field

Split the area into two halves with a clear line, using cones, chalk, a path or a row of trees. Each team places its flag somewhere in its own half where it can be seen, usually near the back. A common rule is that the flag must stay visible and must not be held or guarded from closer than a few big steps. Then mark a jail for each team, usually in a corner of their half.

Walk the boundaries with everyone before you start. Most arguments in capture the flag come from players who did not know where the field ended.

Rules

1. Each team starts in its own half.
2. When the game starts, players may cross the middle line into the other team’s half.
3. In your own half you are safe and you can tag any enemy player who has crossed over.
4. An enemy player who is tagged in your half goes to your jail.
5. A prisoner is freed when a teammate reaches the jail and tags them without being tagged first. Both then walk back to their own half before they can play again.
6. To win, a player must grab the enemy flag and carry it back across the middle line into their own half without being tagged.
7. If the flag carrier is tagged, the flag is dropped or returned to where it started, depending on the rules you agree before the game.

Agree how a tag works before you start: a light touch with one hand is enough. Ban pushing, tackling and pulling clothes, and do not let guards stand right on top of the flag or the jail.

Splitting the teams fairly

The worst moment of any team game is the old captains’ pick, where the same children are chosen last every time. A random split is quicker and kinder: put every name into the Random Name Picker, use “remove and spin”, and deal the names to team A and team B in turn. Then flip a coin flip to decide which team takes which half of the field. For more ways to do this, including how to balance teams, see our guide on how to make random teams.

Players often ask how likely it is that they will end up with their best friend. With two equal teams, the answer is just under one half, and a group of three friends all landing on the same side is a lot rarer:

So in a class of 30, two friends are on the same team about 48% of the time, and three friends only about 22% of the time. If you need certain players apart, for example two very fast runners, put one name on each team first and draw the rest at random.

Strategy tips

• Split each team into defenders, who guard the flag and jail, and attackers, who cross the line.
• Send several attackers at once from different sides; one runner is easy to tag, three are hard.
• Use a decoy: one player runs loudly down one side while another creeps up on the flag from the other.
• Keep at least one fast player free to rescue prisoners, so you do not run out of attackers.
• Change roles at half time so everyone gets to attack.

Variations

• Night capture the flag: played at dusk with glow sticks as flags, or with players carrying torches. Keep the field small and safe.
• Multiple flags: each team hides several flags, and the first team to capture all of the other side’s flags wins.
• No jail: tagged players go back to their own back line and touch it before they can play again, which keeps everyone moving.
• Flag passing: the flag may be thrown to a teammate, but if it touches the ground, it goes back.
• Indoor version: in a sports hall, use beanbags as flags and hoops as jails.

Safety

• Check the field for holes, glass and low branches before the game.
• Set boundaries well away from roads, water and parked cars.
• Agree on a stop signal, such as a whistle, that ends play at once.
• For mixed ages, ask older players to tag gently and let younger ones have a free rescue now and then.

If you want something with less running, try hide and seek, or the playground ball game four square.

At least eight, so each team has four players. The game works best with ten to thirty players and a large open field.
