Unfortunately this particular challenge was rejected by my reviewer. Could you change the checker to this instead?

Have attended 5 event caches (of any type) on each day of the week?

Thank you,

[New] New challenge for GCBGWFW (no replies)

superluc — Tue, 14 Apr 2026 18:06:06 +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

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.

Hello sirs and or madams.

May I please have a challenge checker made for GCBC2TZ.
Sam's challenge for you is to find at least 10 combinations of elevation in 1000' bands, and found month (MMYYYY).
So March 2025, April 2025, and march 2026 would count as 3 seperate found months.
For elevations, the usual works great:
<0, 0-999, 1000-1999, 2000-2999 (or 1' higher if that's easier to code)
May we please include a visual grid with this challenge with found month going down the side and elevation along the top.

Thank you for your time and help.

Hello good sirs and madams.

May I trouble you for a challenge checker.
The challenge for GCBC2TR is to have found all 9 different terrain ratings HIDDEN on 1 calendar day. It doesn't matter what year they were hid, nor what date you find them. Your qualifying finds can be any size, terrain, location, and type except for adventure labs.

If possible can we please include a visual grid. If it helps,

Hello good sirs and or madams.

May I please have a challenge checker made for GCBC2TP. The challenge is to find at least 40 combinations of U.S. State (including Washington D.C.) and found day (1-31). It doesn't matter what month or year the geocache was found, nor when they were hidden. The size, difficulty, terrain, location, and type don't matter either as long as its not adventure labs - they don't count for this challenge.

With 51 U.S. States and 31 days to choose from, there is a maximum possible score of 1581.
May we please include a visual grid with this challenge.

There is a similar challenge already built in case that helps that uses hidden day instead of found day:
