An open point is any point on the board that is not occupied by two or more opposing checkers. You can move your checkers to a point with no checkers on it, a point with one or more of your checkers on it, a point with one of your opponents checkers on it. Remember that you should always move your checkers counter clockwise, moving from your opponents home court to your own.
You can start with any checker you chose.
You can either move one checker twice or move two checkers once. For example, if you roll a 3 2, you can move one checker 3 points over and then 2 points over, as long as it lands on an open point both times. Alternately, you can move one checker 2 points over to an open point, and move another checker 3 points over to an open point.
