The balls

For a two or four player, two sided game, you need four balls. The colors usually used are blue, red, black, and yellow. One side with one or two players plays with blue and black, and the other with red and yellow. For a six player team game, you need six balls. In team play, one side plays blue, black, and green, and the other side plays red, yellow, and orange. In one ball games, you need one ball per player.
