There is a rummy type game and a trivia game featuring the first 8 historical characters. The third game features Kit Kittredge, who was the newest doll at the time. It is a frame game that has little pictures you try to arrange according to your pattern cards. I haven't played that one yet, but it seems a little more complicated than the others.
One of my favorite aspects is the artwork. Each doll's suit shows pictures from each book in her series. This helps players review the stories as they play. The pictures also make the game easy enough for non readers to play. I am sad that AG has discontinued their beautiful illustrations, so I appreciate any opportunity to introduce my kids to the pictures, which really enhance the stories, in my opinion.
The Rummy game, called Threes Please can be used for other card games as well, such as War and Uno. my kids loved this game. My oldest daughter liked the trivia game because she had listened to several of the books and enjoyed answering the questions.
This game is available on the secondary market for about $5-$20. Ebay has plenty in great condition for reasonable prices, so don't pay too much.
I highly recommend these games for boys and girls for education and fun.
