To play you need:

• Board with special markings.
• 30 game checkers divided by color into two groups of 15 checkers. Usually 15 black checkers and 15 white checkers.
• Gaming dice.

The game is played by two players on a special board divided into two halves with a game field marking. The game field consists of 24 numbered narrow triangles (holes), called positions. The positions are combined into groups of 6. These groups are called - house (1-6), yard (7-12), enemy house (19-24), enemy yard (13-18). The house and yard are separated from each other by a bar that protrudes above the playing field and is called a bar. Each player has 15 checkers, usually white and black. Each player may only move checkers of his own color. The initial arrangement of the checkers is as follows: each player has two checkers at the twenty-fourth point, five at the thirteenth, three at the eighth, and five at the sixth. A cube with the numbers 2, 4, 8, 16, 32, and 64 on its edges is used to keep track of the current bet of the game.
The goal of the game is to move all of your checkers to your home board and then remove them from the board. The first player to remove all of his checkers wins the game.

Each side of the board has a track of 12 long triangles, called points. The points form a continuous track in the shape of a horseshoe, and are numbered from 1 to 24. In the most commonly used setup, each player begins with fifteen pieces; two are placed on their 24-point, three on their 8-point, and five each on their 13-point and their 6-point. The two players move their pieces in opposing directions, from the 24-point towards the 1-point. Points 1 through 6 are called the home board or inner board, and points 7 through 12 are called the outer board. The 7-point is referred to as the bar point, and the 13-point as the midpoint. The 5-point for each player is sometimes called the "golden point".

To start the game, each player rolls one die, and the player with the higher number moves first using the numbers shown on both dice. If the players roll the same number, they must roll again until they roll different numbers. Both dice must land completely flat on the right-hand side of the gameboard. The players then take alternate turns, rolling two dice at the beginning of each turn.

After rolling the dice, players must, if possible, move their pieces according to the number shown on each die. For example, if the player rolls a 6 and a 3 (denoted as "6-3"), the player must move one checker six points forward, and another or the same checker three points forward. The same checker may be moved twice, as long as the two moves can be made separately and legally: six and then three, or three and then six. If a player rolls two of the same number, called doubles, that player must play each die twice. For example, a roll of 5-5 allows the player to make four moves of five spaces each. On any roll, a player must move according to the numbers on both dice if it is at all possible to do so. If one or both numbers do not allow a legal move, the player forfeits that portion of the roll and the turn ends. If moves can be made according to either one die or the other, but not both, the higher number must be used. If one die is unable to be moved, but such a move is made possible by the moving of the other die, that move is compulsory.

In the course of a move, a checker may land on any point that is unoccupied or is occupied by one or more of the player's own checkers. It may also land on a point occupied by exactly one opposing checker, or "blot". In this case, the blot has been "hit" and is placed in the middle of the board on the bar that divides the two sides of the playing surface. A checker may never land on a point occupied by two or more opposing checkers; thus, no point is ever occupied by checkers from both players simultaneously. There is no limit to the number of checkers that can occupy a point or the bar at any given time.

Checkers placed on the bar must re-enter the game through the opponent's home board before any other move can be made. A roll of 1 allows the checker to enter on the 24-point (opponent's 1), a roll of 2 on the 23-point (opponent's 2), and so forth, up to a roll of 6 allowing entry on the 19-point (opponent's 6). Checkers may not enter on a point occupied by two or more opposing checkers. Checkers can enter on unoccupied points, or on points occupied by a single opposing checker; in the latter case, the single checker is hit and placed on the bar. A player may not move any other checkers until all checkers belonging to that player on the bar have re-entered the board. If a player has checkers on the bar, but rolls a combination that does not allow any of those checkers to re-enter, the player does not move. If the opponent's home board is completely "closed" (i.e. all six points are each occupied by two or more checkers), there is no roll that will allow a player to enter a checker from the bar, and that player stops rolling and playing until at least one point becomes open (occupied by one or zero checkers) due to the opponent's moves.

A turn ends only when the player has removed his or her dice from the board. Prior to this moment, a move can be undone and replayed an unlimited number of times.

When all of a player's checkers are in that player's home board, that player may start removing them; this is called "bearing off". A roll of 1 may be used to bear off a checker from the 1-point, a 2 from the 2-point, and so on. If all of a player's checkers are on points lower than the number showing on a particular die, the player must use that die to bear off one checker from the highest occupied point. For example, if a player rolls a 6 and a 5, but has no checkers on the 6-point and two on the 5-point, then the 6 and the 5 must be used to bear off the two checkers from the 5-point. When bearing off, a player may also move a lower die roll before the higher even if that means the full value of the higher die is not fully utilized. For example, if a player has exactly one checker remaining on the 6-point, and rolls a 6 and a 1, the player may move the 6-point checker one place to the 5-point with the lower die roll of 1, and then bear that checker off the 5-point using the die roll of 6; this is sometimes useful tactically. As before, if there is a way to use all moves showing on the dice by moving checkers within the home board or by bearing them off, the player must do so. If a player's checker is hit while in the process of bearing off, that player may not bear off any others until it has been re-entered into the game and moved into the player's home board, according to the normal movement rules.

The first player to bear off all fifteen of their own checkers wins the game. When keeping score in backgammon, the points awarded depend on the scale of the victory. A player who bears off all fifteen pieces when the opponent has borne off at least one, wins a single game worth 1 point. If all fifteen have been borne off before the opponent gets at least one checker off, this is a gammon or double game worth 2 points. A backgammon or triple game is worth 3 points and occurs when the losing player has borne off no pieces and has one or more on the bar and/or in the winner's home table (inner board).

Each game starts with a stake of one point. During the game, a player who feels that he has a fairly large advantage in the game can offer a doubling (i.e., doubling the stakes). He can do this only before his turn begins, before he throws the dice. If the player who was offered to double the stakes passes, he surrenders the game and loses one point. Otherwise, he must accept the doubling and play with doubled stakes. The player who accepted the doubling becomes the owner of the cube, and only he can now double the stakes again. Counter doubling of stakes in the same game is called base (or redouble). If the player surrenders at this point, he loses as many points as were at stake before this redouble. Otherwise, the cube passes to him, and the game continues with the stakes doubled again. There is no limit to the number of redubles.

At the end of the game, if the losing player has managed to remove at least one checker from the board, he loses as many points as are currently on the dice (one point if neither player has called dave). However, if the loser has not managed to remove any checkers from the board, he loses the gammon and loses double the number of points. If, moreover, the loser has not removed any checkers and one or more of his checkers remain on the bar or in the opponent's house, he loses the coke and loses triple the number of points.
