Like so many others around the world, the National Puzzlers’ League is saddened and angered by the events of recent weeks. Not just for deaths of the names we know, like George Floyd, Breonna Taylor, Tony McDade, and Atatiana Jefferson, but for the names we don’t, and for the injustices in our nation that allowed their deaths. Black lives matter.
The NPL Board is creating a working group to investigate what concrete steps we can take to 1) make our space more welcome to a more diverse audience and 2) grow and create a more diverse membership. Read the complete statement here.
The National Puzzlers' League (the NPL), founded in 1883, is the world's oldest puzzlers organization. The native puzzle type of the NPL is the flat, a versified puzzle involving wordplay, but League members enjoy many other types of puzzles.
If you enjoy wordplay such as palindromes, cryptograms, crossword puzzles, cryptic crosswords, anagrams, or discovering the word SCHOOLED has the letters in the words SHOE and COLD perfectly interlaced ... you'll probably find it in our monthly publication, The ENIGMA.
For an introduction to both flats and the other kinds of puzzles that are published in The ENIGMA, take a look at our online minisample.

The minisample is also an excellent way to introduce the NPL to your puzzling friends.
English-language flats are unique to the NPL (though there are some similar puzzles in other languages), and we have a complete online Guide to The ENIGMA, the “bible” of the NPL, to help you solve them. In it, you'll find detailed descriptions of almost all the puzzle types found in The ENIGMA, helpful articles about solving and composing, and a brief history of the NPL.
Our collection of word lists are available to everyone. You will also find helpful information on to use regular expressions with word lists to find bases for puzzles.
The National Puzzlers' League hosts an annual convention in July of each year. The convention is in a different city each year, with cities selected two years in advance. Visit the convention site for the latest information. If you're new to the NPL, a convention can be a great “crash course” to the League.
The NPL has about 700 members throughout the US, with a few international members. Membership includes many of the top names in the puzzling world.
Most members of the NPL use a nom (short for nom de plume) instead of their name. Noms have a long tradition in puzzle clubs, predating even the League itself. Symbolically, noms allow all puzzlers to meet as equals, free of the titles and social distinctions that the outside world may demand, and are the only introduction needed to NPL members all over the world.
