The indoor game is different from conventional 11 man football. Here are some of the differences.

Eight Players

• On offense, there are three linemen, three receivers, a quarterback and a running back.

• On defense, three players must be linemen. The others are linebackers or backs.

• There must be separate offensive and defensive starters, but all players can serve as backups on either side of the ball.

Fifty Yard Field

• From goal line to goal line the field is 50 yards long and 28 yards wide. Endzones are a minimum of 5 yards deep and can be rounded to fit hockey board configurations.

Three Men In Motion

• Three offensive players can be in motion at one time. Their first step must be lateral or backward, but then they can move towards the line of scrimmage, but can not cross it till the ball is snapped.

Dasher Boards

• The 4 foot high walls surrounding the field are in play. If the ball carrier hits the wall, he's not down until he is tackled or his forward progress is stopped.

Blitzing

• A defensive player can blitz if he's in the alley (outside shoulders of perimeter offensive linemen and 5 yards off the line of scrimmage). He must signal his intent to blitz. He can. however, bluff.

No Punting

• If the offense fails to make a first down, which is 10 yards as in the regular 11 man game, in 4 downs the ball is turned over to the opposing team, but field goals are allowed.
