How do you play the game of Backgammon?
assistant
To play backgammon, each player must have a set of 15 checkers. The players take turns moving their checkers around the board. Each turn, a player can move one or more checkers on any open line. A player can also move a checker from one point to another within the same group if it's vacant. If a player moves all their checkers off the board, they lose. The first player to get rid of all their checkers wins.
