THE OFFICIAL RULES OF THE UNITED STATES CROQUET ASSOCIATION

These are the complete and official rules for the six wicket grass croquet played in the United States under sanctioned USCA tournament formats. This is the 2006 revision of the rulebook and current as of January 2010.
The Six Wicket Croquet rules include a number of
significant, but non-substantive, changes such as reducing
redundancies, reordering of some material, improvements
in wording and style consistency, inclusion of the individual
rules in the table of contents, and a new numbering system
for the rules.
