The Danish Easter tradition with the teasing letters - gækkebreve - is originally a German tradition with socalled knot letters. They were send in Denmark from 1600 and to 1800. The tradition was that the receiver of the letter should loosen up a knot or solve a riddle that was placed in the letter.
In 1800 the more commercialised letters came in special paper with laces and colours and each year around Easter a book was published with teaser verses.
Today the idea with the teaser letter - gækkebreve - is that especially children make their own letters from paper and write teaser verses with number of dots of the receiver on the letter. Once the receiver receives the letter, he has to guess the sender. If he doesn't guess the sender after three guesses, the receiver owes the sender an Easter egg - and the other way around if the receiver guesses the name of the sender. A fun little Easter game for all - children as well as grown-ups.
