There are several games traditionally associated with Halloween. Some of these games originated as divination rituals or ways of foretelling one's future, especially regarding death, marriage and children. During the Middle Ages, these rituals were done by a "rare few" in rural communities as they were considered to be "deadly serious" practices. In recent centuries, these divination games have been "a common feature of the household festivities" in Ireland and Britain. They often involve apples and hazelnuts. In Celtic mythology, apples were strongly associated with the Otherworld and immortality, while hazelnuts were associated with divine wisdom. Some also suggest that they derive from Roman practices in celebration of Pomona.
