Trick or Treat.: Popular halloween game

The oldest and most well known Halloween party game is Bobbing for Apples, originally known as Ducking for Apples. The game, which originated in the British Isles, dates back to at least three hundred years and originally had something to do with fortune telling as noted by British author W.H. Davenport Adams.

Here's how to play the game:

Fill a large tub or basin full of water.
Place apples into the water, they will float.
Have party guests try to catch and remove apples from the water by grabbing them with their teeth.
Hands are not allowed.

Players will usually get wet when playing this game, so have some towels available for guests to dry off with.

Other games:

Sticky Face

This old fashioned party game is played by hanging sticky treats from the ceiling on long strings, and having players eat the treats without using their hands. In the past, treacle or syrup-coated scones were used, as well as apples covered in toffee.
The updated version of this game can feature any kind of treat. Glazed donuts are a popular modern day choice for this game, as they are easy to tie on to a string and are very sticky. Any type of treat that can be tied to a string will work, the fun part is getting as sticky as possible.

Here's how to play the game:

Tie long strings around sticky treats.
Hang the strings from the ceiling, so that the treats hang down to a length in which players will be able to eat them with their mouths.
Have players stand underneath the treat of their choice, and eat it without using their hands.
