The following video showcases an effective technique for solving mystery geocaches by leveraging other puzzles created by the cache owner to get more insight in how to solve a particular puzzle.

I will demonstrate this technique using a series of mystery caches designed by HistoryJoe23. I want to extend a special thank you to HistoryJoe23 for graciously permitting me to feature his puzzle caches in this video.

Featured in the video are the Pyramid series of HistoryJoe23, starting at GC9RFYV
