My rules are that the pieces move forward 1space only until they are kinged (make it across the board all the way), then they can move forward or back, but only 1 step at a time. His rules changed for kings; they could move as many spaces as they wanted as long as they were diagonal. He also had another rule called dummies. You had to jump a piece if you were given the opportunity, or essentially challenged.
Those simple rule differences change how players strategize the game. I learned that game rules need to be reviewed before playing with new players.
While I thought that this game had no educational value. I did find that I was wrong. It taught me culture. There are different ways to play and in a classroom, students might find it interesting to play with others and discover different ways to play, or even be given different rules to such a simple game before they play. For example, if the class identifies that they all play the same way, then we can add in the other rules that were new to me and perhaps them as well. This might be a good way to teach culture and diversity in a smaller scale.
