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:

Match It

This is an excellent ice breaker type of game, as it requires quite a lot of searching to find your match.

Prepare by acquiring a piece of cardboard for each couple of guests. Cut the card in two using a unique and irregular pattern for each piece. Something like a jigsaw puzzle. Put one half into one pile, and the other half into another pile. Then shuffle each pile. Put each pile into a box.

As your guests arrive, have the women take a piece from one box, and the men from the other. The guests must then attempt to find their matching half. Suggest that when a couple find their match, the man might get them both a drink!
