IFAF Flag Football Rules are based on Tackle rules, but kept short and simple. The structure will follow Tackle Rules, but the content and numbering will not always correspond. The Flag Football Rules Book covers everything to play Flag without knowing the Tackle rules. All important or special things have been determined and ruled. Only some specific information (e.g. specifications of ball) are not covered. If there is a need for more information you will have to look in the Tackle Rules Book (e.g. R 1-3-1).

As a coach or official you will need to understand the flag rules as a whole.

The Football Code of the IFAF Tackle Football Rules is an integral part of the Flag rules.

Flag football is non-contact. Blocking, tackling and kicking are not allowed.

The most important aspect of Flag Football is to avoid contact, it is to make the flags an easy target for the defense, but
in return to demand to pull it without contact.

If you have questions about the rules or interpretations, feel free to contact me and the Interpretations Club.

National Changes

For national competition games it is possible to change rules as follows:

R 1-1-1 Field dimensions can be changed due to game site or age.
