2.8. Challenge checkers
Challenge caches published after April 21, 2015, must include a link to a Project-GC challenge checker. This requirement is ongoing for the life of the cache listing. Visit Project-GC’s FAQ to learn how challenge checkers work and how to create one.
Challenge checker requirements
Your challenge cache may be disabled or archived if the associated challenge checker does not work properly. Make sure that your checker and listing meet these requirements:
- A challenge cache listing can only include one challenge checker.
- The GC code on the challenge checker must match the GC code of the associated challenge cache listing.
- The challenge checker must verify that a player does or does not qualify to log a challenge cache as found.
If you want to include a banner with a challenge checker, you must use an official Project-GC banner.
