Association Croquet
Association Croquet (AC) is the oldest form of croquet that is currently played. Besides having good striking skills, AC involves a lot of strategy and forward thinking. Golf Croquet (GC) players can be initially quite confused about AC as it is a very different game, with its own vernacular and there seems to be much sitting down.
Ricochet croquet (RC) was invented to help GC players transition to AC, however RC has become a popular game in its own right.
This page lists some of the YouTube resources to help understand AC.
John Hutchison of Eastern Shore Croquet Club in Hobart has made some very good short animations that explain getting started in AC, the different AC Shots and some tactics. I've put them in what I consider some order. Just click on each and enjoy.
