Gækkebrev are a great Danish tradition, but like many other Danish traditions, they are fighting to survive amid the country's ambitious digital agenda.

What is a gækkebrev, or gække letter? A single piece of paper, cut into a lace-like design somewhat like a snowflake, sent anonymously in the days before Easter.

A poem is handwritten on the letter, but it is unsigned...except for a number of dots that correspond to the number of letters in the sender's name.

If you can guess who sent the letter, that person owes you a chocolate Easter egg. If you can't guess, you owe them a chocolate Easter Egg whenever they reveal themselves.

Needless to say, gækkebrev are very popular with small children looking for candy.

(The "gække" refers to a vintergække flower that used to accompany the letter back in the day)

But the tradition is slowly dying out, thanks to Denmark's widespread digitalization. Paper letters have almost disappeared; it's quite possible to go for months without receiving any physical mail at all.

Stamps and coins are also dying out. While Denmark got a new king more than a year ago, I've yet to see his image on any stamps or coins...because I so rarely see stamps or coins.
