Book Cover Bingo is a game I launched in June 2010. You can read the introductory post here.
I created Bingo boards made up of book covers from the authors featured in my Creative Spaces interview series (up to that point). Multiple titles were "called out" each day until contestants scored a "Bingo" with 5 titles in a row. 15 books from the Creative Spaces authors and illustrators were offered as prizes.
Book Cover Bingo was a fun success with 140 participants of all ages. I would love to do the game again if I can figure out a way to generate the game boards more quickly than the time-consuming approach I originally used. (Create Word table, drag and drop cover jpegs into square in random fashion, repeat 139 times.)
But I am a fan of games in general and might try to cook up some other less time-consuming ideas. Please email me if you'd like to be put on a "game notice" list.
