Participants must be at least 18 years old, United States citizens or on an applicable visa, including an F-1 student or work visa. We prefer participants who are eligible to work in the United States.

This competition is open reference and open language.

OpenBracket is an individual, head-to-head, single elimination, playoff bracket-style competition. Help from teammates will not be permitted.

OpenBracket is fierce competition, but it's all in the spirit of fun. We require an atmosphere of inclusivity and completely free of any kind of harrassment. We love the Code of Conduct developed by Girl Develop It, and we will enforce it at OpenBracket.

The Doubletree by Hilton Hotel Downtown Wilmington at 700 N King St, Wilmington, DE 19801.If you are checking into the hotel on Friday, October 20th and checking out on Sunday, October 22nd, OpenBracket will make your hotel reservations.

OpenBracket is a head-to-head, algorithmic tournament challenge. That means all participants will compete directly with other participants in several rounds. In 2016, the event format included teams, but that is NOT the case in 2017, which will only involve individual competitors.

The challenges will look like those offered on Hackerrank.com, the service we’ll be using for the in-person championship. Participants will be given personalized algorithmic challenges they’ve never seen before. Winners will be objectively graded on their performance.

There will be activities throughout the weekend, including several side competitions to keep you engaged. Plus, we’ll make sure the competition itself is interesting enough that you’ll want to follow. Throughout the weekend, there will be live music, competition, local coffee and beer and other competitions and activities.

• Laptop and charger (we can accommodate limited desktop setups that you choose to travel with but ask you be respectful of other participants and their space. Please tell us if you plan on doing this so we can reserve space by contacting win@openbracket.org.)
• If you want hard wire internet access (more on that below), bring a Thunderbolt adapter or usb 3.0/ethernet adapter.
• Backup laptop in case of emergency. We will not be providing hardware or backup computers.
• Any overnight gear if you are staying over. (You should!)
• A positive, competitive and fun spirit.

We’ll be following the Hackerrank Terms of Service here. (hackerrank.com/terms-of-service)

The Queen Theater, our venue, is wired, but we’ve boosted the signal with Wilmington startup WhyFly to offer robust internet in two ways. There will be dependable wifi and the option to tap into wired connectivity. Don't forget your thunderbolt adapter or usb 3.0/ethernet adapter if you want a hardwired connection.
