Moderators will move threads from Checker requests into this forum after a while when it has been decided that the challenge checker isnt possible for one or another reason. The threads should not be moved right away. The challenge owner should have a chance to adjust his requirements if that helps. https://project-gc.com/forum/list?10 Thu, 16 Apr 2026 03:53:04 +0000 Phorum 5.2.23 https://project-gc.com/forum/read?10,121071,121071#msg-121071 https://project-gc.com/forum/read?10,121071,121071#msg-121071
Find at least 1 cache (any type) with the initial of the Reviewer you published. Where you go from A to Z.

Example:

Cache found...

Cache published by reviewer "Antony", so the letter A already fulfills the challenge.

The GC for the challenge is GCBM2JE.

Can you help me generate a checker for GCBMR3D?

It would involve finding 26 caches whose names begin with each of the different letters of the alphabet (excluding ñ): A B C D E F G H I J K L M N O P Q R S T U V W X Y Z.

Any type of cache is valid, and it doesn't matter if it's active or inactive.

I need three checkers for three challenges.

I'm not sure if the challenge is possible or if I can request three in the same message.
Perhaps it would help since they're similar.

They would be three challenges of this type:

GCBMR3D - Collect 2 souvenirs in one day and one year
GCBMR1T - Collect 3 souvenirs in one day and one year
GCBMR3J - Collect 4 souvenirs in one day and one year

They can be from any day of the year any year, Starting Jan 1, 2026

ich würde gern einen Challenge-Cache "Cache Around the Clock" erstellen (noch erfülle ich die Bedingung selbst nur erst 99-prozentig), für den man ein Event zu jeder Stunde des Tages besucht haben muss. Mit einem entsprechenden Checker könnte ich auch überprüfen, wer die Bedingungen schon erfüllt.

Die Challenge lautet:

Besuche 24 Events, die jeweils zu einer unterschiedlichen Stunde von 00:xx Uhr bis 23:xx Uhr beginnen (die Minuten können vernachlässigt werden). Es zählen alle Arten von Events (normales Event, CITO, Community Celebration Event, MEGA, GIGA, Block Party). (Qualifizieren kannst du dich beispielsweise durch ein Event um 00:15 Uhr, ein CITO um 01:00 Uhr, ein Event um 02:30 Uhr usw. bis 23:xx Uhr.)

Der Link zum Cache lautet:

Ich würde mich freuen, wenn das klappen würde. Besten Dank im Voraus!

Hello everyone,

I'd like to create a challenge cache called "Cache Around the Clock" (I'm currently only 99% fulfilling the requirements myself), for which you have to attend an event every hour of the day. With a suitable checker, I could also verify who has already met the requirements.

The challenge is:

Attend 24 events, each starting at a different hour between 00:xx and 23:xx (the minutes can be ignored). All types of events count (regular event, CITO, Community Celebration Event, MEGA, GIGA, Block Party). (You can qualify, for example, by attending an event at 00:15, a CITO at 01:00, an event at 02:30, etc., up to 23:xx.)

The link to the cache is:

https://coord.info/GCBKV74

I would be very happy if this works out. Thank you in advance!

If you look at the matrix when it is fulfilled, the ratings give you a smiley face.

It would be nice if the matrix is shown in the checker and only the specified values are displayed.

For example: the value D1.5 T4.0 remains red until the value is met five times. Then the field with the value turns green. And that for all ratings.



That is, if I don't meet any of the ratings, I see a red smiley in the matrix, and if I meet all the ratings, I see a green smiley. If I only fulfill a few evaluations, then I see only red and green fields with the number of current finds of the corresponding evaluation in them.

The GC code for this challenge is GCBKNRW Bitte lächeln (Challenge)

To qualify, you need to have attended 2 events in 2 different countries, within 24 hours of each other. You have to take into account the difference in the time zones. As an example, my Regina event was at 5pm local time. The next day, my Cancun event was at 6pm. But since there is 1 hour difference, it was really 5pm in Regina still, so they were officially 24 hours apart. Here's another example: if you attend an event in Winnipeg at 2pm local time on Friday, then fly to Madrid, you have until 9pm on Saturday to attend that event! But if you fly to Hawaii, you only have until 10am on Saturday during the winter, or 9am in the summer (Hawaii doesn't change time)...]]> Applefish ARCHIVE Checker requests (impossible) Tue, 03 Mar 2026 23:05:32 +0000 https://project-gc.com/forum/read?10,119211,119211#msg-119211 https://project-gc.com/forum/read?10,119211,119211#msg-119211 I would like a new checker for a new challenge :
