If you're new here, welcome! We would just like to inform you of a few things before you compete.*

All competitors must be familiar with the WCA regulations.

Here is a video link the basic overview of competing:

Please be aware that certain events have time constraints in order for us to stay on schedule. Make sure you read the events page so you understand what those are.


Q: Do I use my own cube to compete?
A: YES! You are responsible for your own hardware in order to compete. This means you should bring your own cube, or arrange to borrow a cube from a friend.

Q: What is the normal age of competitors at these events?
A: All ages are welcome, but in general competitors are between 10 and 20 years old. Don't let this stop you though, everyone can and should cube!

Q: What do I do when I walk in?
A: There is NO CHECK-IN. If you registered online, just have fun and hang out with other cubers. We will be calling people up, so just wait for your name/group to be announced.

Q: How do I find results?
A: All results are posted on the WCA page within a week after the competition finishes. However, for the day of competing, go to Cubecomps.com to find information about current events. This is also where you will find information about 2nd and 3rd rounds of events. Remember, the results are entered by a human so please be patient if you do not see your results immediately.

Q: Why am I not on the registration list yet?
A: Make sure you pay you entrance fee in order to be placed on the registered list, which will also guarantee you a spot in the competition. If payment may be any issue, use the contact button to talk to us, and see if we can work out another payment strategy.

Q: Are there age divisions?
A: Nope! All competitors compete together.
