Backgammon is a classic abstract strategy game. Each player has a set of 15 "men" that must be moved from their starting positions, around, and then off the board. Dice are thrown each turn, and each player must decide which men to move based on the outcome of the roll. Players can capture each other's men, forcing those men to restart their journey around the board. The winner is the first player to get all 15 men off the board.
