At the beginning all checkers are off-board (as if they were on the bar). An opening roll is played as usual, but the winner has an option to re-roll the dice for his first move. On doubles, the numbers are played twice as in standard backgammon, and besides, the player gets an extra roll.
Played with the standard initial layout, but the player who wins the opening roll, re-rolls to make his first move. Doubles are not played twice. If a player has a checker on the bar and his opponent’s home board is completely closed, both players roll one dice (as on the opening roll), and the winner of the roll decides what point of the close home board he wants to open. This is done by moving all, but one checker from the selected point onto the bar as if they were hit. Checkers can be born off from the lower point even if there still are checkers on a higher one. There neither are gammons, nor backgammons. The game is played without doubling cube.
The setup is similar to standard backgammon, but one checker is removed from the player’s 8 point and the opponent’s 12 point, and these two checkers are placed at the opponent’s 2 point, making 4 back checkers. The rest of the standard backgammon rules apply.
The game starts with all 15 checkers at the rightmost point of the far side of the board. Both players move their checkers in the same counterclockwise direction. The checkers must be moved to the quarter of the board opposite to the starting point and then born off. There is no hitting. Checkers can be placed only at open points. One checker on a point can not be hit and therefore blocks the point. Only one checker can be removed from the initial pile per roll, except the first roll when two checkers can be removed.
The winner of the first roll re-rolls to make his first move. Backgammon scored only if the opponent has a checker on the bar. The game is played without doubling cube.
An ancestor of modern backgammon. All checkers start off the board and move in the same counterclockwise direction starting from the same point. Three dice are used and there are no doubles. Checkers can not be moved to the second half of the board until all checkers has entered the board.
