Analysis of information sources in references of the Wikipedia article "Backgammon" in Vietnamese language version.
Rules of play describe a particular variation of backgammon and on this there is no disagreement among international tournaments. In fact, tournament rules sets do not usually specify these rules but might instead refer, as in the US Rules, to the 'commonly accepted rules of backgammon.' It is understood that this means backgammon as played at international tournaments, not another variant in its own right such as plakoto, portes, fevka or portos.
To start the game, each player throws a single die. This determines both the player to go first and the numbers to be played.
