The resources.
Rules, deliverables, and real problem statements from past years. Read the handbook for your category before the weekend, and use the past problems to get a feel for scope and format.
Kompetition Handbook
The kompetition handbook sets out the rules and deliverables for each individual kompetition: what you build, what you hand in, and how it is judged. Read the section for the category you entered.
Official Rulebook
The official rulebook covers the general rules and expectations for the whole event: eligibility, conduct, team composition, and what happens on the day. It applies to every category.
Past Problem Statements
Each kompetition runs on a problem statement that describes the design challenge. These are the statements from past years, so you can get a feel for the scope, format, and expectations before yours is revealed on the day.
Innovative Design and Communications are new for 2027, so they have no past problem statement yet.
