We have two major rules:

1. Teams can consist of betwen 1 and 4 people.
2. The projects submitted for judging cannot have been started prior to the start of the hackathon. In other words, teams can plan their projects in great detail, but they cannot begin writing code until they arrive at the hackathon.

Additionally, we are partnering with MLH this year, which means that our hackers must follow their code of conduct which can be found here.
