If you need some colonial games to fit your party theme, obviously a chain toy store isn’t going to have any. You can do fun old-timey games like the clothes pin drop. You may already have a jar and clothes pins, which are all that is required. Otherwise, your best bet is a historical site (or its website). My family’s collection of games came from Mount Vernon, the George Washington birthplace, and Old Salem. You can also find games at Monticello.
