Backgammon Tournament Rules — How Competitive Backgammon Works

Competitive Backgammon

Backgammon has a vibrant competitive scene with tournaments worldwide. Unlike casual play, tournament backgammon uses specific rules and formats designed to test skill and provide fair competition.

Match Play

How It Works

Tournament matches are played to a set number of points:

• Each individual game scores 1 point (single), 2 points (gammon), or 3 points (backgammon)
• Points are multiplied by the doubling cube value
• The first player to reach the target number wins the match

Common Match Lengths

Key Tournament Rules

The Crawford Rule

The most important tournament-specific rule:

When a player reaches match point (needs exactly 1 more point to win), the doubling cube is not available for the next game.

Why: Without the Crawford rule, the trailing player would always double immediately (they have nothing to lose). Crawford preserves the leader’s advantage.

After the Crawford game: The cube returns to normal. The trailing player typically offers an immediate double.

The Jacoby Rule (Money Play Only)

In money play (not match play), gammons and backgammons only count as extra points if the cube has been turned at least once. If neither player doubled, any win is just a single.

Purpose: Encourages cube activity and prevents long, drawn-out games where one player clearly has a gammon but the trailing player won’t resign.

DMP (Double Match Point)

When both players are 1 point from winning the match:

• The cube is irrelevant (no point in doubling)
• Gammons don’t matter (any win ends the match)
• Play becomes purely about winning the game

Post-Crawford Strategy

After the Crawford game, with the trailing player behind:

• The trailing player should double immediately — they can only benefit from the cube being in play
• The leader should evaluate each position carefully before accepting or declining

Tournament Format

Single Elimination

The most common tournament format:

1. Players are paired in brackets
2. Losers are eliminated
3. Winners advance until a champion is determined
4. Match lengths may increase in later rounds (e.g., 5-point early, 7 in the middle, 11 for the final)

Double Elimination

Similar to single elimination, but a player must lose two matches to be eliminated:

• Creates a “winners’ bracket” and “losers’ bracket”
• Gives every player the chance to recover from one bad match
• The final involves the winners’ bracket champion vs. the losers’ bracket champion

Round Robin

Every player plays every other player:

• Requires more time but is the most fair format
• Provides good data for ranking players
• Used in some championship events

Clocks and Time Controls

Modern tournaments use chess-style clocks:

• Each player has a set amount of time for the entire match
• Common allocation: 2 minutes per point of the match + 12 seconds per move
• If your time runs out, you lose the game in progress
• Clocks ensure matches finish in a reasonable time

Etiquette and Conduct

Tournament backgammon has established etiquette:

• Announce doubles clearly — place the cube facing your opponent at the appropriate value
• Handle dice properly — both dice must land flat on your half of the board
• Don’t rush your opponent — they’re entitled to their clock time
• Shake the dice thoroughly — don’t “set” the dice
• Be gracious in victory and defeat

Getting Started

1. Play online — platforms offer rated match play
2. Study match equity tables — understand how the score affects strategy
3. Learn Crawford rule implications — it changes strategy dramatically
4. Find local tournaments — many cities have backgammon clubs
5. Start with short matches — 5-point matches are good for beginners
