Flag: Some leaders may hold a banner, which usually has the sponsor's logo, competition logo or publicity information. These flags are usually held high, providing players with an easy-to-identify target.

Clothing: In order to stand out from competitors, leaders may wear bright and distinctive clothes. These clothes usually bear the logo of competition or special design.

Logo: The team leader can carry a logo with the time of the current game or other important information written on it for the team members' reference.
