With the plethora of Challenge Caches appearing, it was only a matter of time before a Challenge appeared that requires multiple Challenge Cache finds to qualify – so here it is ..

To claim this cache you need to have found at least 10 other Challenge Caches. To be clear that is Challenge Caches identified by the blue ? symbol and NOT the recently introduced “Challenges”.

So what Counts as a Challenge Cache?

A cache that requires you to pre-qualify by finding one or more caches of a particular Class, Rating level, Age or Type. They normally include the word “Challenge” in the cache title, but there are a few exceptions. All the following are Challenge Caches for the purpose of this Challenge :

1) Difficulty/Terrain grid bingo, e.g. “Gridlocked - Capital Style” (GC1QBQN)
2) Total finds by type, e.g. “Blue Diamonds 1000 Cache Challenge” (GC23WZ8)
3) Caches found by date placed, e.g “In the Year 2002” (GC1Y9MT)
4) Cache finds on every day of month or year, e.g. “A year lost – 365 days of caching” (GC254H4)
5) Cache finds based on features of GC numbers , e.g. “QR Challenge” (GC33DDP)
