National Puzzlers League
If you enjoy wordplay (and, frankly, who doesn’t?), then you’ll love the National Puzzlers League. The NPL is a self-described eclectic crowd who enjoy all forms of wordplay and are continuing the traditions of “The World’s Oldest Puzzlers’ Organizationâ€.
Puzzle Solving 101
I am often asked how I go about solving puzzles. As I’m interested in geocaching, I decided to create a series of geocaches that teach people how to solve some of the most common types of puzzles as well as to give them the skills to solve other types of puzzles.
The result of this effort is the Puzzle Solving 101 Series of geocaches. Each cache in the series offers a lesson on a particular topic of puzzle solving. The description of each cache offers a description of the topic as well as solving tips. Each lesson also contains an example to solve using the tips presented in the lesson – the solution to each example puzzle is the location of a geocache in Broward County, Florida.
