CubeDepot will be sponsoring and vending at this competition!

For those of you new to cubing, WELCOME!

We wanted to let you know this event is perfectly fine for cubers of any age and experience. We just ask you know a couple things before coming to compete...

First, please be familiar with the WCA Regulations, found here:

Of course, those regulations contain a lot of legalese, so we have a video made specifically for new cubers, just to show them the basics of competing. This video will explain most of what any cuber competing for the first time will need to know.

If you have any questions after this video, we will be having a new competitor tutorial, Saturday morning of the competition. That would be the perfect time to ask those questions and clear up any confusion.

If you are stoked to compete and ready to sign up, head over to the registration tab, click register, and fill out the information it asks for. This will help you get set up the WCA's system and one step closer to your first official solve!


Q: Do I use my own cube to compete?

A: YES! You are responsible for your own hardware in order to compete, however, we will have a vendor at this competition, from which you can buy puzzles if your current ones have seen better days.

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 is the competition like?

A; Competitions are a bunch of tables where nerds like us get to sit and discuss our favorite thing, Cubes! Of course in addition there is competing, which will occupy one side of the competition hall, where you will see lots of timers flickering with contestants new personal bests, and a vendor, where you can purchase all you cubing related needs. Most competitions have a break for lunch, and the competing is split up into heats, as to better organize who competes when. (Check the Groups tab and listen at the competition for more info on this.)

Q: How do I find results?

A: All results are posted on the WCA page a couple of days after the competition finishes. However, for the day of competing, go to to find information about current events. This is also where you will find information about 2nd and 3rd rounds of events.

Q: Why am I not on the registration list yet?

A: Make sure you pay you entrance fee in order to be automatically placed on the registered list, which will also guarantee you a spot in the competition. If payment may be any issue, or you are not sure if you can attend, use the contact button to talk to us, and see if we can work out another payment strategy, or have you pay on arrival at the compeition. No matter what you situation may be however, please register online. It is much easier for us to have you register now and pay later, then to have to input information at another time.

Q: Are there age divisions?

A: Nope! All cometitors compete in the same group.

Q: Can I have fun at this event?

A: HECK YES! Cubing is amazing, and we sincerely hope you enjoy the competition!
