A point occupied by a single piece of either color is called a blot. If an opposing piece lands on a blot, the blot is hit and placed on the bar.
A blot or an empty point is considered to be open.
Any time a player has one or more pieces on the bar, his first obligation is to enter those piece(s) into the opposing home board. A piece is entered by moving it to an open point corresponding to one of the numbers on the rolled dice.
If neither of the points is open, the player loses his turn. If a player is able to enter some but not all of his pieces, he must enter as many as he can and then forfeit the remainder of his turn.
After the last of a player's pieces has been entered, any unused numbers on the dice must be played, by moving either the piece that was entered or a different piece.
