Sean Effel and Dana Ostberg founded the first branch of the Squarefour four square league in Boston the fall of 2003. The league closed its doors in 2012 but we still receive heaps of emails asking for rule clarifications, advice for games, and ideas for tournaments. We're glad this website continues to be a resource for four square players all over the world. Look at the FAQ and see if someone has already asked your question, and if you still aren't satisfied then we're happy to help you work it out. We'll be glad to hear from you.
