I played the game when I was in summer camp in the late sixties and during the seventies. We had loads of fun. We called it bottle caps. I found this site and it bought back fond memories. We are having a reunion and will be designing one to bring back those memories. We had almost one of these in each of our cabins. Great game to play inside when it’s raining. Most of the guys at the reunion will be over 40yrs old. I hope we remember the game. Should be a blast. I also played in Philadelphia.
