Frequently Asked Questions
Everything you need to know about using this application.
How does the backgammon pip counter calculate the race position?
The pip counter tool works by assigning a numerical value to the position of every checker on your board. In backgammon, a 'pip' is the distance a checker needs to travel to reach the bearing-off tray, ranging from 1 to 24. By inputting the exact number of checkers on each of the 24 points, our algorithm sums the total distance for all your checkers, providing an instant and accurate race count. This calculation is essential for determining who is leading the race and by how many pips. By knowing your exact pip count versus your opponent's, you can make informed decisions about whether to race, hold your position, or play conservatively to avoid being hit. The interface is designed for rapid entry so you can use it even during fast-paced live games.
What is match equity and why is it important in backgammon?
Match equity represents the statistical probability of winning a match based on the current score and the number of points remaining to reach the match length. In a tournament setting, your doubling cube strategy must change depending on the match equity; for example, at certain scores, you might be 'near-redouble' territory, while at others, you play very conservatively. Our match equity calculator uses standard tournament equity tables to provide you with the winning percentage for both you and your opponent. By understanding your equity, you can determine if a position is a 'drop' or a 'take' for the cube, or if you should be the one to initiate the double. This is a critical skill for any serious competitive backgammon player.
