This competition is managed financially by Colorado Cubers, a non-profit association. We understand that the registration fees for this competition are higher than usual, but please recognize that everyone working these competitions is a volunteer and our organization will be taking a considerable loss as a result of this event. We hope to be able to put on a unique experience that will be enjoyable for everyone.

There is no mask policy at the venue, but we still encourage anyone that wishes to wear one to do so. If the situation regarding COVID-19 worsens, masks may become a requirement closer to the competition.

You must read this tab before registering to ensure you are able to get into the zoo.

To register for this competition, you must pay a registration fee of $55. As a part of your registration fee, you will be given tickets to enter the zoo as well as a voucher for lunch at one of the zoos restaurants - it is enough to cover an entree and a non-alcoholic beverage.

You must pay $48 for each guest you bring. We will be providing them with the same package as competitors, with admission to the event, the zoo, and lunch.

Once registration closes, which will be three weeks before the actual competition to allow time to prepare, you and your guests will be provided with a link to claim your tickets to the zoo.

On the day of the competition, we will hand you a physical voucher for lunch at the zoo.

If you have any questions please contact us using the form on the information page!

Before the competition, you will receive a card/nametag with personalized information detailing your events and what group you will be competing in for each event in an email. We will be relying on competitors to help by judging whenever they are not competing, especially with our small competition size. Judging is very easy, and is a great way to make time fly!

We will provide a judging and competitor tutorial at the beginning of the day, right before the start of the first event. This will allow anyone with questions about how to judge to be properly prepared when they are expected to help.

We will need help judging for the second/final rounds of events as we can not assign staff for those in advance. Spectators are encouraged to learn how to judge; you do not need to know how to cube in order to be a great judge. Having enough judges ensures that we stay on schedule and are able to leave on time.
