The article was in the paper I receive as well and they had "the rules of the game" included.
Differences
1. 1-15 instead of 1-10
2. All players on the field can take a pass.
3. There must be a so-called "clean exchange" of the football, meaning the QB must pitch, hand off, or throw the ball before it crosses the LOS.
4. A field goal is worth 4 pts, a PAT is worth 2 pts if kicked and one point if it is run or passed into the EZ.
5. The slaugther rule: After 1/2 time, if a team is up by 45 pts or more, the game is called off.
6. A six-man field is 40-80 yards instead of the traditional 100-50.
Seen 8-man, but not 6-man. SOUNDS VERY INTERESTING!!
