Card game:Grandmama's Improved Game of Useful Knowledge

McLoughlin Brothers introduced the successful "Grandmama's" series of educational card games in 1887. Players assumed the roles of "scholars" and designated one participant to act as "preceptor." Scholars tested their knowledge answering questions posed on cards, and the preceptor confirmed or corrected them from a companion book of answers. Grandma's game subjects included geography, arithmetic, useful knowledge, Bible studies, and riddles. Games such as this endure to the present day, with the most recent examples being the Trivial Pursuit series of board and card games, as well as online versions.
