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.
