There are a large number of traitional Easter games and customs in the Christian world. Many of these games incorporate easter eggs. Although adopted into the Christian tradition of Easter, these games are probably based in ancient fertility cults (this is a classic example of syncretism). Of these the most well known, widespread and popular until the modern times are the egg rolling, egg hunt, egg tapping, and egg dance. Their rules may vary in different cultures and localities. At the same time, there exist less known peculiar customs. Nowadays child entertainers and kindergartens invent various new Easter games, often adapting well-known games to Easter topics, such as word puzzles involving Easter-related words. These are not discussed in this article.
