The game is an accompanying activity for the Women in History: Guess Who Game and other activities in the Famous Women in History: Women’s History Month Bundle. It assumes that the players have already familiarized themselves with the women featured in the game and encourages them to use their previous knowledge to play the game.
Is it possible to use this as stand-alone game though? Yes, though it would be more useful in conjunction with other activities from the bundle.
There are two types of cards available in the game. If you have played the Women in History: Guess Who Game before, use the cards that have only the names. That will provide a challenge and check how well the players remembered the information about the women and their achievements. If you have not played that game or if the players are young, start with the cards that have all the basic information. It will still provide the logical challenge of deciding who did what, but with some available prompts.
