Try your hand at constrained writing and you could win a trio of DVDs for word lovers: “Spellbound,” “Wordplay,” and “Word Wars”! 

Lipograms (banning a particular letter), palindromes (reading the same backward and forward), alliteratives (each word starts with the same letter), anagrams ­(rearranging the letters in a sentence, for example, to create a new sentence) — ­whatever your puzzle passion, send your ­example by March 1 to or to ­“Constrained Writing,” Princeton Alumni Weekly, 194 Nassau St., Suite 38, Princeton, NJ, 08542. We plan to post submissions and announce the winner in the April 7 issue. To read some examples of constrained writing by students, click here.
