From the Publisher's Website:
The One Page Dungeon Creation Contest!
The idea of the contest is to ask readers to create one dungeon level in an edition-less format (ex: you can name monsters but you don't provide stats for them) using the template and submit it for the contest. We'd judge the entries based on criteria such as 'most evocative setting', 'Funniest entry', 'Most creative use of a Trap' and so on. Once we've named winners, we'll be compiling a FREE PDF of the winners/runner-ups and releasing it to the community at large.
User Summary:
This series gathers together all of the documents that have been published as a result of this competition. It is anticipated that this will become an annual event, with regular releases of new PDFs of competition entries.
Note that each contest year also is represented as an annual series.
