National Puzzlers' League

The National Puzzlers' League (NPL) is a nonprofit organization focused on puzzling, primarily in the realm of word play and word games. Founded in 1883, it is the oldest puzzlers' organization in the world. It originally hosted semiannual conventions in February and September of each year,[1][2] but conventions are now held annually, in July.
