Backgammon is a two-player race game played with fifteen checkers each on a board of twenty-four points. Players roll two dice, move checkers around the board, and try to bear all fifteen off first. Hits and blocked points add tactics to the race, and a single game typically lasts five to fifteen minutes.

Backgammon belongs to one of the oldest continuous game families in the world, with ancestors appearing across Persia, Rome, and the broader Mediterranean. The modern form stabilized over centuries and became a club and tournament favorite because the dice create variety without erasing the importance of skill.
That mix of race and contact is what makes backgammon so durable. Some turns are about pure efficiency; others become tactical fights over blots, anchors, and board control.
Each player moves fifteen checkers around the board according to the dice. The goal is to bring all your checkers into the home board and bear them off before your opponent does.
Backgammon strategy changes with the position. A racing position rewards efficiency, while contact positions reward timing, safety, and well-timed aggression.
Match play with the doubling cube is the standard competitive format, but casual sessions may skip the cube entirely. Nackgammon and hypergammon are well-known relatives that change the opening structure or number of checkers.

A blot is a single checker on a point by itself. It can be hit by the opponent and sent to the bar.
Bearing off is the final phase where you remove checkers from the board once all of them are in your home board.
Some positions are pure races, but many games include contact, hitting, and board-building decisions that make skill matter a great deal.
Both, in a well-studied balance. The dice decide any single game, but checker-play and cube decisions compound, so the stronger player wins reliably over a session or match. That is why backgammon supports serious tournament play while staying friendly to newcomers.
The doubling cube is a die marked 2, 4, 8, 16, 32, and 64 that raises the stakes of a game. A player who feels ahead can offer a double; the opponent must either accept and play on for twice the value or concede immediately. It was introduced in America in the 1920s and is standard in match play.
A single game usually takes five to fifteen minutes. Competitive matches are played to a points target — often 5, 7, or 11 points — so a full match can run from twenty minutes to well over an hour. Online play tends to be quicker because the board handles the dice and legal moves for you.
You forfeit the roll, either partly or completely. If only one die can be played legally you must play it, and when either number could be played but not both, the higher number takes priority. A checker on the bar must re-enter before any other checker may move.
A gammon is a win where the loser has not borne off a single checker, and it scores double. A backgammon is rarer still: the loser has borne off nothing and still has a checker on the bar or in the winner’s home board, scoring triple. In money and match play these multipliers stack with the doubling cube.
The tables family that backgammon belongs to stretches back thousands of years, with related race games played across ancient Persia, Rome, and the wider Mediterranean. The modern name appeared in seventeenth-century England, and the doubling cube — the last major addition to the rules — arrived in 1920s America.
The pip count is the total distance, in points, that your checkers must still travel before they can all be borne off. Both players start at 167 pips, and comparing counts tells you who leads the race. Checking the count before big decisions — especially whether to race or keep contact — is a habit that separates stronger players.
