Master backgammon with proven opening moves, doubling cube strategy, and advanced tactics.
The opening roll sets the tone for the entire game. There are 15 possible non-double opening rolls (since doubles can't occur on the opening). Each has an optimal play developed through decades of expert analysis and computer simulations.
| Roll | Best Play | Why It Works |
|---|---|---|
| 3-1 | Make the 5-point (8/5, 6/5) | The single most valuable point on the board. Creates a strong anchor in your home board. |
| 6-1 | Make the bar-point (13/7, 8/7) | Starts building a prime. The bar-point is crucial for blocking escaping checkers. |
| 4-2 | Make the 4-point (8/4, 6/4) | Solid home board builder. Works well with the 6-point you already own. |
| 5-3 | Build 3-point (8/3, 6/3) | Extends your home board, though the 3-point is less valuable than the 5 or 4. |
| 6-4 | Run (24/14) | Escape one back checker to the safety of the midpoint. |
| 6-5 | Run (24/13) | Move one back checker to your opponent's bar-point (your 13-point). |
| 6-3 | Run (24/15) | Escape one checker partway. Avoids leaving a double blot. |
| 6-2 | Run (24/16) | Brings one back checker forward, though it's still exposed. |
| 5-4 | Run (24/15) | Moves one back checker to relative safety. |
| 5-2 | Run (24/17) | Advances one back checker, but leaves a blot in the opponent's outer board. |
| 5-1 | Slot the 5-point (13/8, 6/5*) | Aggressive play that slots the key 5-point, risking a hit for positional gain. |
| 4-3 | Run (24/20, 13/10) | Brings one back checker down and builds toward the bar-point. |
| 4-1 | Split and slot (24/23, 13/9) | Splits the back checkers and slots toward the bar-point. |
| 3-2 | Make the 11-point (13/11, 13/10) | Builds a defensive anchor in the outer board. Alternative: 24/21, 13/11. |
| 2-1 | Split and slot (13/11, 6/5*) | Aggressive. Slots the 5-point and starts the 11-point. High risk, high reward. |
Key Insight: The 5-point is the most important point to make early. Rolls like 3-1 that make it immediately are excellent. The bar-point (7-point) is the second priority, forming the foundation of a strong blocking game.

The middle game is where backgammon separates beginners from experts. There are four main strategic themes to understand:
A prime is a wall of consecutive points controlled by you (2+ checkers on each point). A 6-point prime completely blocks your opponent's checkers — they can't jump over it.
A blitz is an aggressive all-out attack aimed at hitting multiple opponent checkers and closing out your home board.
When you're behind in the race, the holding game is your defensive strategy. You maintain an anchor in your opponent's home board and wait for a hitting opportunity.
A backgame is an extreme holding strategy where you own two or more anchors deep in the opponent's home board. It's a desperation tactic when far behind.
Bearing off is the endgame. Your checkers are home — now you need to remove them efficiently without leaving unnecessary shots.
Pip Counting Basics: The pip count is the total number of pips (dice points) needed to bear off all your checkers. A rough count helps you decide whether to play safe or race. If you're ahead by 10+ pips, play safe. If behind, you must race aggressively.
Multiply checkers on each point by the point number and sum:
Compare your pip count to opponent's to decide strategy. Ahead? Play safe. Behind? Take risks.
The doubling cube is what elevates backgammon from a simple race to a game of psychological warfare and mathematical precision. Mastering it is the difference between intermediate and expert play.
The general rule: double when you have roughly 70% winning chances or better.
| Win Probability | Action |
|---|---|
| 50%–65% | Too early to double (too good to double) |
| 65%–75% | Double (optimal window) |
| 75%+ | You may have waited too long (opponent should drop) |
When your opponent doubles, you face a critical decision:
Why 25%? Mathematically, if you drop, you lose 1 point. If you take and lose, you lose 2 points. So taking is correct if you win more than 1 in 4 games (25%). This assumes no gammon risk — adjust if gammons are likely.
A market loser is a position so volatile that your opponent might have a clear drop next turn. You should double immediately even if slightly premature, because waiting might mean they drop for free next turn when you're winning by even more.
Once you own the cube, you control all future doubles. Use this power wisely:
In match play, the score changes doubling strategy dramatically:
Don't leave checkers exposed unless there's a clear strategic reason. Every blot is a target. Beginners leave blots carelessly and get punished by experienced players who hit and build primes.
Piling 4+ checkers on a single point wastes mobility. Spread your checkers across multiple points to maximize flexibility and coverage. Stacking is called "crunching" and limits your options.
Many beginners ignore the cube entirely. This is leaving huge value on the table. If you have a clear advantage, double. If opponent doubles and you're losing badly, drop. The cube is half the game.
Backgammon rewards calculated aggression. Don't hide in the corner. Hit when it makes sense. Make points. Apply pressure. Passive play loses to active opponents who seize the initiative.
You can't make good strategic decisions without knowing the pip count. Are you ahead or behind? By how much? This determines whether you run, fight, or hold. Learn to count quickly.
If you hold an anchor in opponent territory, don't abandon it prematurely. That anchor is your lifeline in a holding game. Breaking it too soon lets your opponent seal their home board and roll to victory.
Match play strategy differs radically from money play. At 2-away, 2-away (tied near match end), cube decisions change. Learn match equity tables or use gammon equity calculators.
Building a 6-point prime is great, but don't sacrifice all your forward checkers to do it. You need checkers ahead to win the race once your opponent's trapped checker escapes (and it will).
Don't mindlessly bear off. Look ahead. Clear high points systematically. Avoid leaving gaps. One careless blot during bear-off can cost you the game.
Bad dice happen. Jokers (unlikely losses) happen. Don't let frustration cloud your judgment. The best players maintain discipline and make optimal plays regardless of recent luck. Emotion is the enemy of good backgammon.
Match equity is your probability of winning the match from a given score. For example, at 4-3 in a 7-point match, the leader has roughly 70% match equity.
Match equity tables guide doubling decisions in match play. The cube value changes based on the score — sometimes you double earlier, sometimes you hold back, depending on match equity swings.
When one player reaches 1-away from winning the match, the Crawford Rule triggers: the cube is disabled for one game.
The Jacoby Rule (used in money games, not matches) states that gammons and backgammons only count if the cube has been turned.
Some positions are volatile (luck-dependent, high variance) while others are stable (skill-dependent, low variance).
The effective pip count adjusts the raw pip count for positional factors like wastage (stacked checkers), crossovers (movements between quadrants), and gaps.
EPC gives a more accurate picture of who's really ahead. A player with fewer pips but poor distribution may actually be behind in EPC.
Experienced players memorize reference positions — standard positions with known equities and doubling decisions. These serve as mental anchors.
Examples: "2-away, 2-away DMP", "pure race down 8% in pips", "5-prime vs. single anchor". Knowing these lets you compare current positions to reference benchmarks.
