There are several games traditionally associated with Halloween parties.
The most common is dooking or bobbing for apples, perhaps derived from the Roman celebration of Pomona.
Apples were put into a barrel that had been filled to the brim with water and an individual would have to catch an apple by catching them in their mouth with out using their hands. Once an apple had been caught, it was traditional to peel the apple and drop the peelings into the barrel to see if the peel would spell out a letter. Whatever letter the peeling formed itself into would be the first initial of the participant's true love.
A variant involves kneeling on a chair, holding a fork between the teeth and trying to drop the fork into an apple. Another common game involves hanging up treacle or syrup-coated scones by strings; these must be eaten without using hands while they remain attached to the string, an activity which inevitably leads to a very sticky face.
Some games traditionally played at Halloween are forms of divination.
In Puicíní (pronounced "pooch-eeny"), a game played in Ireland, a blindfolded person is seated in front of a table on which several saucers are placed. The saucers are shuffled and the seated person then chooses one by touch. The contents of the saucer determine the person's life for the following year. A saucer containing earth means someone known to the player will die during the next year, a saucer containing water foretells travel, a coin means new wealth, a bean means poverty, etc.
In 19th-century Ireland, young women placed slugs in saucers sprinkled with flour. The wriggling of the slugs and the patterns subsequently left behind on the saucers were believed to portray the faces of the women's future spouses.
In North America, unmarried women were frequently told that if they sat in a darkened room and gazed into a mirror on Halloween night, the face of their future husband would appear in the mirror. However, if they were destined to die before they married, a skull would appear. The custom was widespread enough to be commemorated on greeting cards from the late nineteenth and early twentieth centuries.
