Played in Philadelphia Pa. in late 70’s.We called it caps or poison.Yesterday,since the kids were out of school for just one day, bored out of thier minds.I introduced them to this game,just like me they loved it.It started with four kids,by the time I was finished tring to explain all the rules and finishing the first game.There now were nine kids waiting for the next game. Plus neighbors telling me how they played this game.So,I decided to see if there were any official rules,if so please get in touch. —BY THE WAY STILL A GREAT GAME!
