Anchors = Wins
When I was in elementary school many years ago, one of the playground games that we enjoyed was Tug of War. We would divide ourselves, usually by choosing a team captain for each of the two teams and then the captains would take turns picking their teammates.
Each team would have the same number of players. Someone would draw a line in the dirt in the middle of the two teams. Then, each side would grab an end of a long rope and with a count to 3, the game would start and each player would pull with all their might.
