Ph0wn Badge Contest Edition 2022

We were very sorry the Badge Contest had to be cancelled in 2021. It will be back in Ph0wn 2022 Edition. Prepare your badges!

Bring your favorite badge at Ph0wn CTF: one you built yourself or simply a badge you got at a former conference.

We will display all badges at the venue.
Each participant present at Ph0wn will vote for his/her favorite badge. The winner receives a prize (to be determined, but we hope for something geek).
This contest is meant to be fun and educative. As usual, remain fair play, and enjoy!


  • Who. Each ph0wn participant may only supply one single badge ("badge competitor") . Authorized visitors or the organization staff may supply a badge, but they are not entitled to the winner's prize. If the badge is refused for a reason or another (see below), participant may submit another one.
    Each ph0wn participant or authorized visitor may vote ("voters"). The organization staff does not vote, unless there is a tie at the end.
  • Registration. Each badge competitor will hand over his/her badge in person to the Ph0wn organization staff. More details to come. Probably, badges will be collected at the entrance.
  • Code of Conduct. Badges which do not follow the Code of Conduct are refused. Badge competitors and voters are expected to follow the Code of Conduct too.
  • Tech. Badges are expected to be former badges of conferences or self made electronic badges. Example of badges. If an identical badge has already been registered, the staff will refuse it (unless it is customized one way or another). Badges should be physically and electrically safe. They should not disrupt CTF challenges - check with Ph0wn staff if in doubt. Badges bigger than 20cm x 20cm x 20cm may be refused. If your badge requires some extra equipment: bring it and prepare it . If this equipment takes too much place, the organization staff may have to decline your submission.
  • Using the badges. Participants: please handle the badges with care.
    Badge competitors: while we expect all participants to follow the Code of Conduct, you remain responsible for your badge.If you do not want participants to touch your badge, say so and place a visible sign or sticker on it. We won't be held responsible for badge damage or loss.
  • Votes. Each ph0wn participant or authorized visitor may vote only once, and for a single badge. To vote, people are given a physical token. They must provide this physical token to the organization staff to vote: no physical token, no vote! Badge competitors may vote, including for their own badge :) A Ph0wn participant may redeem his/her physical token to another person, that person can then vote in his/her name. Selling, stealing, blackmailing (etc!) participants for their physical token is absolutely prohibited...
  • Winner. The badge competitor with the most votes wins the contest. Votes are counted by the Ph0wn organization staff, ph0wn participants may watch the count. Tie: if several badge competitors get the same count of votes, depending on available prizes, the Ph0wn organization staff may have to select only one winner. The organization staff decides.
  • Prize. We expect to be able to provide a small geek prize to the winner. However, in the unlikely case we have no available prize, the winner will only win glory !
  • Picture. Badge competitors accept people take pictures of their badge. These images may go for instance on social networks . If badge competitors do not wish this, please do not supply a badge.
  • Promotion. Badge competitors may promote their badge (online, or on site). However, they may not buy votes, attempt to corrupt voters etc. In all cases, promotion/Advertisment must comply with Code of Conduct.
  • Leave with your badge.Each badge competitor must take his/her badge back home at the end of the competition. Remaining unclaimed badges may end in our personal museum.
