Register for the Cosplay Competition

During the pre-judging portion of the event, judges will inspect each costume, inquire as to how they were designed and created, and answer questions contestants may have about the contest. All costumes must be pre-judged in order to be eligible.

Costumes from all genres (video game, comic book, anime, movies, television, etc. ) are acceptable and should have associations with Gaming in some form. Mashups and original designs are also permitted. The majority of your costume must be homemade, although purchased item costumes and modified items are acceptable.

Pre-judging will occur on Level 4 of the convention centre between 11.30 and 1pm each day. All contestants must register for the competition and have their costume pre-judged during this time, although contestants will not be required to stay for the full pre-judging period.

Contestants will be divided into 4 different categories during pre-judging. Contestants will be asked which category they prefer during pre-judging, although judges retain the right to move a contestant into a higher category if they feel a costume deserves to be recognized at a higher skill level.
