A game of Backgammon is won when a player 'bears off' all their checkers.
The player wins the number of points at stake which are indicated by the
cube or just 1 point if the cube was not used assuming the losing player
has removed at least one checker from the board.
Gammon (Double Game)
If the losing player has not removed any of their checkers from the board
a gammon occurs. In this scenario the player wins twice the amount
indicated by the cube.
Backgammon (Triple Game)
When the winner bears off all of their checkers before their opponent is
able to bear off any and still has checkers in their opponent's home board
or on the bar then Backgammon occurs. In this scenario the winner gets
three times the amount of points indicated by the cube
