Backgammon - Complete Guide

Backgammon is one of the oldest known board games, with origins tracing back nearly 5,000 years to ancient Mesopotamia. Archaeological excavations at the Royal Cemetery of Ur (modern-day Iraq) uncovered game boards dating to 2600 BCE that closely resemble modern backgammon. Similar games appeared in ancient Egypt, Rome (Tabula), and Persia (Nard).

The game evolved through centuries of play across cultures. The Romans were passionate players—Emperor Claudius even wrote a book on the game. Medieval Europeans developed variations, and by the 17th century, the game we recognize as backgammon had emerged in England, where it gained its current name (possibly from "back game" or the Welsh "bach" meaning small + "gammon" meaning battle).

Backgammon experienced waves of popularity. It was a gambling favorite in coffeehouses and clubs throughout the 18th and 19th centuries. In 1920s America, an unknown player in a New York gaming club invented the doubling cube, revolutionizing the game's gambling aspect and adding a new strategic dimension.

The 1970s brought a worldwide backgammon craze, sparked by Prince Alexis Obolensky's promotion of international tournaments. Professional players emerged, books were published, and the game became a symbol of sophisticated leisure. Today, online play and computer analysis have deepened understanding of correct strategy, while tournaments offer significant prize money and attract players from around the world.

Backgammon is played on a board with 24 narrow triangles called "points," arranged in four quadrants of six points each. Each player has 15 checkers of their own color.

Setup: Players sit opposite each other. Each player's home board and outer board are on their right and left respectively. The initial position places checkers at specific points: 2 on the 24-point, 5 on the 13-point, 3 on the 8-point, and 5 on the 6-point. The two players' setups mirror each other.

Objective: Move all 15 checkers into your home board (points 1-6), then "bear them off" (remove them from the board). The first player to bear off all checkers wins.

Moving: Roll two dice and move checkers according to the numbers shown. You may move one checker the sum of both dice, or two checkers using one die each. Doubles allow four moves of that number. You must use both numbers if legally possible; if only one is playable, use the higher number.

Point Ownership: A point with two or more of your checkers is "made"—your opponent cannot land there. A point with a single checker is a "blot" and vulnerable. A point with opponent's checkers is blocked to you.

Hitting: Landing on a blot sends that checker to the "bar" (the center divider). Before making any other move, checkers on the bar must re-enter through the opponent's home board by rolling a number corresponding to an open point.

Bearing Off: Once all 15 checkers are in your home board, you may bear off by rolling the exact point number or higher. For example, rolling a 6 can bear off from the 6-point. If you roll a number higher than your highest occupied point, you may bear off from the highest point.

The Doubling Cube: Before rolling, a player may propose doubling the stakes. The opponent must either accept (take) or concede (pass/drop) the game. The cube starts at 1 and can be doubled to 2, 4, 8, etc. Only the player who last accepted a double may propose the next one.

Backgammon strategy balances racing (advancing checkers quickly), blocking (creating obstacles), and attacking (hitting opponent's blots).

Opening Moves: Learn standard opening moves for each dice combination. For example, rolling 3-1: make your 5-point. Rolling 6-1: make your bar-point. These have been analyzed extensively—don't reinvent the wheel.

Making Points: Building a "prime" (six consecutive made points) is powerful—opponent checkers behind it cannot escape. Prioritize making points in your home board and blocking points in your opponent's path.

The Running Game: When ahead in the race (your checkers are closer to bearing off), avoid contact and focus on advancing quickly. Count the "pip count" (total points your checkers must travel) to know your racing position.

The Back Game: When significantly behind, establish anchor points deep in your opponent's home board. Hope to hit a late blot as they bear off. Risky but sometimes the only winning chance.

Blot Hitting: Hit when it slows your opponent, especially when they're about to escape or when they'll have difficulty re-entering (your home board is partially blocked). Don't hit just because you can—sometimes it's better to make a point.

Doubling Cube Strategy: Offer a double when you estimate your winning chances exceed 50% (ideally around 65-70%). Accept a double if your winning chances exceed 25%. These are simplified guidelines—actual decisions depend on match score and position details.

Risk Assessment: Learn to count "shots"—the number of dice combinations that hit your blot. A direct shot (6 pips or less away) is dangerous; indirect shots (7-12 pips) are less so. Balance risk and reward.

Bearing Off: Once bearing off, avoid leaving blots if possible. When you must leave a blot, leave it where it's least likely to be hit. Calculate whether to play safe or go for a "gammon" (winning before opponent bears off any checkers).

Backgammon has spawned numerous variants:

Acey-Deucey: American military variant. All checkers start off the board. Rolling 1-2 (acey-deucey) lets you play that roll, then choose any doubles, then roll again. Creates wild swings in fortune.

Nackgammon: Created by Nick "Nack" Ballard. Starting position moves the back checkers from the 24-point to the 23-point. Results in more hitting and complex games.

Hypergammon: Only 3 checkers per player, starting on the 24, 23, and 22 points. Fast, tactical games ideal for learning checker play.

Tavla (Turkish Backgammon): Checkers start off the board and enter from the same side. No hitting—you cannot land on opponent-occupied points at all.

Plakoto: Greek variant where landing on a single opponent checker "pins" it (covers but doesn't send to bar). Very different strategic considerations.

Fevga: Another Greek variant. No hitting or pinning. Pure racing with blocking. Checkers move in the same direction.

Gul Bara: Both players move in the same direction around the board. Hitting sends the checker to the opponent's starting area.

Chouette: Multiplayer variant where one player (the "box") plays against a team. Team members take turns rolling, consulting on decisions. The winner rotates into the box.
