Backgammon Match Play: Rules, Strategy & Scoring Explained (2026)

Match play is the standard format for all competitive backgammon — from club nights to world championships. Understanding match play rules and strategy is essential for any serious player. It differs significantly from money game backgammon in ways that affect almost every decision you make.

Key Takeaways

Match play means the first player to reach a target score (e.g., 7 points) wins the match, not a single game
Games are worth at minimum 1 point; gammons = 2 points, backgammons = 3 points, all multiplied by the cube value
The Crawford Rule applies when a player is one point from winning: no doubling cube in that game
Match equity — your probability of winning the overall match — drives all cube and game decisions
Correct cube decisions in match play differ significantly from money game because match score changes the value of winning or losing
When significantly behind in a match, take more gamble-oriented risks; when ahead, play more conservatively

What Is Match Play?

In match play, two players compete in a series of games. The first to accumulate a target number of points wins the match. Match lengths are defined by their target score:

Match Length	Points Needed
1-point match	1 point
5-point match	5 points
7-point match	7 points
9-point match	9 points
11-point match	11 points
25-point match	25 points (World Championship final)

How Points Are Scored

Each game is worth a base of 1 point, multiplied by the doubling cube value, and modified by the type of win:

Win Type	Points
Single (normal win)	1 point
Gammon (opponent bears off 0 checkers)	2 points
Backgammon (opponent on bar or in your home board)	3 points

With the cube: All values are multiplied by the current cube value.

Example: You win a gammon with the cube at 4. You score 2 × 4 = 8 points.

The Crawford Rule

The Crawford Rule is the most important match play rule. It works as follows:

When one player reaches match point minus one (one point short of winning), the very next game is the Crawford game.
In the Crawford game, the doubling cube cannot be used by either player.
After the Crawford game, the doubling cube is available again in all remaining games.

Why it exists: Without the Crawford Rule, the trailing player would immediately double, and the leading player would be forced into a difficult decision. The Crawford Rule gives the leading player one game free from cube pressure.

Example: In a 7-point match, player A reaches 6 points. The next game is the Crawford game (no cube). After that game, the cube is back in play.

Post-Crawford Strategy

After the Crawford game, the cube strategy changes dramatically for the trailing player:

If trailing by 1: Double immediately on your first turn. Your opponent should nearly always take.
If trailing by 2: Gammon wins help, so cube early but consider when gammons are possible.
If trailing by more: The more points you need, the more important gammons and backgammons become. Sometimes you must play for them even at the risk of losing more.

Match Equity

Match equity is the probability (expressed as a percentage) that a player will win the overall match from a given score.

Match equity tables (METs) are calculated based on the mathematical probability of winning a series of independent games. Here are common equity values for a 7-point match:

Score (You – Opp)	Your Match Equity
0-0	50%
2-0	60%
4-0	72%
6-0	83%
0-6 (Crawford)	17%
3-3	50%
5-3	63%

These values drive all cube decisions: a double that gains equity in a money game might cost equity in match play.

How Match Play Changes Cube Decisions

This is where match play strategy diverges most sharply from money game.

Take Points Vary by Score

In money game, the take point is roughly 25%. In match play, it varies enormously:

Leading player: Often takes more conservatively (risks giving away the match).
Trailing player: Often takes more aggressively (needs to generate points).

Doubling Windows Change

The “correct” time to double depends on how many points a gammon or backgammon would gain relative to a normal win, which in turn depends on the match score.

Key concept: Gammon value — In match play, gammons are worth more when you need 2+ points to win, and essentially worthless when winning by 1 point would end the match.

Example: The “Free Drop”

If you’re leading 6-0 in a 7-point match, your opponent needs 7 points to win. A double to 2 means they still need 7 points if they win — the cube level doesn’t matter. In this case, dropping is correct even with a strong position, because taking risks giving the opponent match-winning momentum.

The Jacoby Rule and Match Play

The Jacoby Rule (gammons and backgammons only count if the cube has been turned) is not used in match play. It’s a money game rule only. In match play, gammons and backgammons always count their full value.

Practical Match Play Tips

Count match equity, not just game equity: Before doubling, ask “does this improve my match equity?” not just “am I ahead in this game?”

Know the score at all times: Score awareness should be constant. Players who forget the score make systematic errors.

Adapt your game plan to the score: Down 3-0 in a 7-point match? Play more aggressively, go for gammons, take more cubes. Up 5-0? Play solidly, avoid risks.

Learn the key scores: Not all scores require complex calculation. A few key score pairs recur constantly in match play — learn the equity for 0-0, leader at match point minus one, and trailer at match point minus two.

Common Match Play Mistakes

Not knowing the Crawford game rules: Playing with the cube in the Crawford game is illegal and should be caught immediately.

Playing money game in match play: Making cube decisions based purely on win probability without considering match equity is a major leak.

Ignoring gammon considerations: In many match scores, the difference between a gammon and a regular win is decisive. Adjust your game plan.

Over-aggressive cubing when ahead: When holding a match lead, avoid turning the cube too eagerly — you’re giving the trailer opportunities to double back.

Frequently Asked Questions

What is match play in backgammon?

Match play is a format where two players play multiple games until one accumulates the target number of points. Unlike a single game, you’re optimizing for winning the match rather than maximizing points in any one game. Most competitive backgammon uses match play.

What is the Crawford Rule in backgammon?

The Crawford Rule states that when one player reaches match point minus one (one point short of winning), the immediately following game is played without the doubling cube. After that Crawford game, the cube becomes available again.

How do you score a match in backgammon?

Each game is worth at least 1 point. Gammons count 2 points, backgammons count 3 points. All values are multiplied by the current cube value. The match ends when one player reaches the target score.

How does the doubling cube work differently in match play?

Take points, double windows, and the value of gammons all change based on the current match score. A position that’s a clear double in money game might be wrong to double in match play, and vice versa. Match equity tables guide these decisions.

What is post-Crawford play in backgammon?

Post-Crawford play refers to all games after the Crawford game. With the cube available again, the trailing player typically doubles immediately on their first turn (called “free beavers” in some circles), since losing doesn’t worsen their position and winning at higher cube values helps.

Is match play used in all backgammon tournaments?

Yes — virtually all official tournaments, from club events to world championships, use match play format. The match length varies by event and round. Early rounds often use shorter matches (5 or 7 points); finals use longer matches (11, 13, or 25 points for the World Championship).
