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:

One Minute Walk

Draw two chalk lines on the floor, a distance apart. This will probably be as far as the room allows.

Have all of the players remove their watches.

The object of the game is for the players to walk from one chalk line to the other in EXACTLY one minute. They must keep moving at all times, the other players will judge this, You use a stop watch to keep the time.

You can usually have two players trying the challenge at a time. It is much harder than it sounds!
