LAWS OF THE GAME

Most games that we grow up playing are governed by rules.  Soccer, however, is played following the Laws of the Game.  They are designed and implemented by FIFA, the world governing body (based in Switzerland), and then handed down to each country's national federation.  The United States Soccer Federation reviews the Laws of the Game and then modifies them for youth soccer and passes it down to us through the Eastern Pennsylvania Youth Soccer Association.  More information on the LOTG can be found below.
