You compete by getting the most badges. Every team can get all badges, and they must be claimed by writing blog posts where you explicitly write what badge you are going for. Most badges are about implementing a solution using a particular kind of technology or framework.
There are additional badges that can be won by showing good team spirit, lightning talks and doing stupid things for fun. There's room for interpretation and it's important to talk to the judges and know that you'll get points for and not.
Every day the judges award a team "Category King" for each category, so it's important to communicate, write blog posts and demonstrate your solution to the judges throughout the competition.
Category points: Each judge will rank your team against the others, and at the end of day three, this ranking will give you points to be counted in your total score. Each category will give 100 points to the winner of the category, and less and less point the further down you have been ranked. But, if you don’t deliver anything in a category, your score here will be 0.
Badgepoints: When you claim and get approved a badge, that badge will give you 10 points to be counted in your total score (mark that you can only gain points for a badge one time), except for the Dooh badge, this will give you -10points,
Housepoints: All teams will be a part of a house, and the house can gain points both by getting badges approved and by doing something extra ordinary that makes the judges want to give your house extra points! “10 points to Gryffindor!” (does it sound familiar?). At the end of the event, the teams in the house with most points, will all get 10 points extra to count in their total score.
The last day of the hackathon each team has to deliver a short-written presentation of the solution they have created as a blog post.
The judges now have to make the final decisions of which teams that deserves to get the wildcard points.The judges will present top 3 teams, and finally announce the winner of ACDC.
The winning team gets to take home the antlers and also gets to inscribe their company name at the very honorable winning teams plate placed on the antlers.The winning team then gets to keep the antlers for 1 year until the next ACDC event.
