[Awaiting feedback] GCBN6EP 1K' Elevation bands / Hidden month (MMYYYY) X 300 (1 reply)

CheekyBrit — Mon, 13 Apr 2026 22:09:02 +0000

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.
May I please have a visual grid included in the checker.

If it helps, here is a similar challenge checker that uses found month:

Thank you for your time and help.
Cheers,

CheekyBrit — Mon, 13 Apr 2026 18:03:42 +0000

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,
here is a similar challenge checker that works on difficulty instead of terrain:

CheekyBrit — Mon, 13 Apr 2026 18:04:20 +0000

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:

Find a cache hidden more than 25 years ago.
Find 25 of any non-event cache type except traditional (Note: these must be the same type, so 25 multis, 25 Wherigos, etc.)
Find a cache in 25 different Georgia (US State) counties.
Complete a 25-day streak
Attend 25 events of any type

Please let me know if you have any questions!

[Resolved] GCBN35W Year and day (31) hid X 200 challenge (2 replies)

CheekyBrit — Sun, 12 Apr 2026 17:43:38 +0000

Hello good sirs and or madams.

May I please have a challenge checker made for GCBC35N. The challenge is to find at least 200 combinations of hidden year and hidden day (1-31). It doesn't matter what month the geocache was hidden and you can find these on any date you wish. 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 27 hidden years thus far and 31 days to choose from, you currently have a maximum possible score of 837.
May we please include a visual grid with this challenge.

It is possible to completely fill this grid with the current 2000 and 2001 caches out there but quite a few days are down to a single cache. Blacking this out is so much harder than the Jasmer.

Thank you for your time and help.
Cheers,
