As a change from running a Treasure Hunt - here is a great childrens game. Follow the links for other party games to entertain your kids:

The Treasure Hunt

This game does require a little more preparation, but you will find it worthwhile.

For each player take a long length of string or ribbon. At one end tie a small present. Hide the present away from view. The strings are then tangled together, wound around chair legs, over and under furniture, finally all ending at the same point.

Give one string end to each child.

The game is for the children to unravel their string and reach the present hidden at the end.
