IFAB Laws of the Game: The IFAB Laws of the Game serve as the foundation for how the game of soccer is played. Professional organizations and competitions use these Laws of the Game verbatim, but CSA has made modifications to the Laws for CSA competitions. To view the IFAB Laws, visit the official IFAB website for full rules or view the Simplified Laws of the Game website for a simpler, easy to understand version.
