As a change from running a Treasure Hunt - here is a great party game for adults or grown-ups. Follow the links for other party games to entertain your guests - whatever their age:

Shapes

Each person is given a plain postcard, and with their eyes closed, makes six randomly placed dots on the card.

The cards are then collected, shuffled and dealt out to each guest. Everyone now has to draw some object, using the six dots as the principal points of their artistic effort. Of course, a great deal of latitude must be allowed in the interpretation, but the chief idea is to make the players draw something that shows skill, and at the same time is controlled by the dots.

Allow 10 minutes for the efforts, then collect the cards and place on a pin board, or display in some way. Allow the guests to vote on the winner.
