  2. Respect the Platform: Do not attempt to attack the platform or infrastructure. Focus on solving the challenges provided.
  3. No Sharing Flags: Do not share flags with other teams. Each team must solve the challenges independently.
  4. Fair Play: No cheating or use of unfair means to gain points. Play honestly and ethically.
  5. Challenge Restrictions: Some challenges may have specific restrictions. Please read the instructions carefully before attempting.
  6. Reporting Issues: If you encounter any issues or bugs, report them to the competition organizers immediately.

Prizes

Team-Based Prizes

Our winning team takes home four (4) tickets to GopherCon 2026, while our second placed team takes home four (4) full-day workshop passes to GopherCon 2026, and our third place team takes home four (4) half-day workshop passes to GopherCon 2026.

The winning teams are determined as the three teams which have the highest score in points at the close of the competition. In the event of a tie, number of challenges solved will be utilized as a tiebreaker. In the event that further tiebreaker is required, the tied teams will be called to the Challenge Series area for a final tiebreaker challenge.

Individual Achievement Awards

We have a set of four (4) individual Achievement awards that players can acquire by meeting certain achievements throughout the course of the competition. The criteria for these challenges will be shown when they've been achieved.

Prizes

Each Achievement award comes with a prize of one half-day workshop pass for GopherCon 2026.
