Answers to the most common questions about backgammon rules, strategy, terminology, and gameplay.
The doubling cube is a special die marked with the numbers 2, 4, 8, 16, 32, and 64. It allows players to raise the stakes during a game. Before rolling on your turn, you can propose to double. Your opponent must either accept (and the game is worth twice as much) or refuse and concede the game at the current stake. The doubling cube is used in money games and match play, adding a critical strategic layer beyond the dice and checker movement.
No. Checkers always move forward — from higher-numbered points toward your home board (points 1-6). The only exception is when a checker is hit and sent to the bar; it must re-enter the game through the opponent's home board and travel the full distance again. You never voluntarily move a checker backward.
Both are types of enhanced victories. A gammon occurs when you bear off all 15 checkers while your opponent has not borne off any — it counts as a double win (2x the stake). A backgammon occurs when you bear off all checkers while your opponent has not borne off any AND still has a checker on the bar or in your home board — it counts as a triple win (3x the stake).
You can only bear off once all 15 of your checkers are in your home board (points 1-6). On each roll, you may remove a checker from the point matching the die number (e.g., roll a 4 to bear off from the 4-point). If you roll a number higher than your highest occupied point, you bear off from the highest occupied point. If a checker is hit during bearing off, it goes to the bar and must re-enter and travel back to your home board before you can resume.
The universally best opening roll is 3-1: make the 5-point, the single most important point on the board. Other strong openers: 6-1 (make the bar-point), 4-2 (make the 4-point), and 5-3 (make the 3-point). For rolls that don't make a point, like 6-2 or 5-4, the best play usually involves running a back checker or splitting your back checkers. Opening theory is well-established — memorizing the best plays for each of the 15 possible opening rolls gives beginners an immediate edge.
When you roll doubles (both dice show the same number), you play that number four times instead of two. For example, rolling double 6s means you make four separate moves of 6 pips each. Doubles can be devastatingly powerful — double 6s in the opening or double 5s making the 3-point and 1-point are game-changing rolls. However, you still must be able to legally play each move; if some moves are blocked, you may not be able to use all four.
A blot is a single checker sitting alone on a point. Blots are vulnerable — if your opponent lands on your blot, it gets "hit" and sent to the bar. From the bar, the checker must re-enter through the opponent's home board before you can make any other moves. Leaving blots is a calculated risk: sometimes you must expose a checker to make a strategic play, but unnecessary blots can cost you the game.
A prime is a row of consecutive made points (points with two or more of your checkers). A 6-point prime is a complete blockade — no opponent checker can pass it because the maximum dice roll is 6. Building a prime in front of one or more opponent checkers is one of the strongest strategies in backgammon. Even a 4- or 5-point prime is extremely powerful.
The Crawford Rule applies in match play (playing to a set number of points). When one player reaches match point minus one (needs exactly 1 more point to win), the next game is the "Crawford game" and the doubling cube cannot be used. After the Crawford game, the cube is available again for all subsequent games. This rule prevents the trailing player from immediately doubling to 2 (which they would always do since they have nothing to lose).
Both, but skill dominates in the long run. Any single game involves significant dice luck — a beginner can beat a world champion with fortunate rolls. However, over a series of games or a long match, the stronger player wins the vast majority of the time. Studies have shown that top backgammon programs (like GNU Backgammon) win approximately 60-65% of games against intermediate players, and the human world champion regularly defeats amateur opponents despite dice variance.
A pip count is the total number of pips (points) all your checkers must travel to bear off all 15. It tells you who is ahead in the race. The starting pip count is 167 for each player. Knowing the pip count is essential for doubling decisions, choosing between running and blocking strategies, and evaluating bearing-off positions. On SuitedGames, the pip count is displayed automatically so you can focus on making the best moves.
The bar is the raised ridge running down the center of the backgammon board, dividing it in half. When a checker is hit (an opponent lands on your blot), the hit checker is placed on the bar. A player with checkers on the bar must re-enter them into the opponent's home board before making any other moves. If the opponent's home board is fully blocked (all six points made), the player on the bar cannot enter and loses their turn.
