What purpose do the bonus points after a player wins a game of Gin Serve?
Let's say two players agree to play a game to 100 points. At the end of the game, the typical rules call for bonus points to be awarded: 25 points for each winning hand, 100 points to the winner, double points for a shutout... Why?
If I was the player that reached 100 first, what good are even more points?
I'm assuming that this is a method for placing wagers on the game?
And how (if at all) do bonus points factor into games where the players agree to a "best of five games (e.g.) arrangement?
