I am looking to create a series of challenges where they are required to find a number of caches in different counties (or possibly states) based on Fibonacci sequence. So 1 find in 1st county, 2 in second, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610

For this first one I was planning to say Traditional only (would have others for other Types and Sizes)

Please let me know if you feel there would be any issues or rule conflicts.

My first cache is GCBN96M

You have to have found the oldest cache in at least 10 countries. All countries that award country points in geocaching should count. Thanks, Coolekuh!

[Resolved] New challenge for GCBGWFW (8 replies)

superluc — Wed, 15 Apr 2026 17:54:42 +0000

Hello

May I please have a new challenge checker made for GCBGWFW
The challenge is to find at least 97 combinations of meters elevation bands and hidden month (MMYYYY).
Your elevation bands would be 0-1000 m, 1001-2000 m, and more than 2001 meters.
Hidden month would be any of the 308 months since the game began May 2000, so March 2025, April 2025, and March 2026 would all be different.
The max possible score is somewhere in the 924 range, but that number grows with every passing month.
May I please have a visual grid included in the checker.

If it helps, here is a similar challenge checker but more complete that uses found month:
https://project-gc.com/Challenges/GCBC2TZ/113783
My challenge only has 3 different heights

Thank you for your time and help.

[Resolved] A new challenge checker for GCBN7BT "Challenge Log the D/T-matrix for challenge caches" (2 replies)

SKroff — Tue, 14 Apr 2026 15:55:21 +0000

Hi!

I would be grateful if it is possible to create a challenge checker for me, on my idea below. As always, I will thank the checker creator in the cache text when I send it to review when the checker is done. This time I hope it's quite easy to create the checker.

SPECIFICATION:
The checker should count all logs for mystery caches with the attribute "Challenge cache". The difficulty and terrain factors between 1-5 counts (= 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5 in both directions, full D/T matrix, 81 squares in total). All of these 81 squares must be filled for having completed this challenge. No demands for anything else (like cache sizes, countries or dates).

If it helps: I have found two challenge caches that has the exact same specification: The full D/T matrix for challenge caches only: GC9ETW9 and GC9G8A7.

I fullfill the demands of course, but only *1. There are above the limit of ten needed cachers in the near area who fullfill it. Apart from the two caches I mentioned, there's nothing that should not get this cache published. The two caches are more than an hour away, which is needed for the Swedish additions to the guidelines according to Sweden Reviewers. All this will be presented to the reviewer team when sent to review. If you - despite my investigations - see something that is against the guidelines, please get back to me! :-)

The GC-code for this planned cache is GCBN7BT and is going to named "Challenge Log the D/T-matrix for challenge caches".

Thank you so much in advance!

Best regards
SKroff

If it’s possible - can the output show the matrix table fulfillment (with numbers or ticks)?

Hello

May I please have a challenge checker made for GCBN6EP
The challenge is to find at least 300 combinations of 1000' elevation bands and hidden month (MMYYYY).
Your elevation bands would be <0', 1-1000', 1001-2000', 2001-3000', and so on until Everest, the highest cache in the world.
Hidden month would be any of the 308 months since the game began May 2000, so March 2025, April 2025, and March 2026 would all be different.
The max possible score is somewhere in the 4620 range, but that number grows with every passing month.
