There are multiple things a first-timer must know before competing. All newcomers must be familiar with the WCA Regulations before competing. There is a video here for the basic overview of the rules.

In addition, please read this document before coming to the competition to learn about the procedures for judging. Thanks to Olivér Perge and Niki Placskó for providing this detailed judging information document.


When you arrive, you will receive a card/nametag with personalized information detailing your events and what group you will be competing in for each event. In addition, you will also receive staffing assignments. All competitors are expected to help at this competition. For each event you sign up for (except Fewest Moves), you will be assigned to help out for just one group of that event. If you do not arrive to help during your scheduled event, and there are not enough staff members, we reserve the right to disqualify you from competing.

We will provide a judging tutorial at the beginning of the day, right before the start of the 3x3x3 speedsolve event. This will allow anyone with questions about how to judge to be properly prepared when they are expected to help. We hope that this system will fairly divide up the judging of the competition and make the competition run smoothly for all.
