How about an option to start the least number of required games in the x wins/points/games match at once?
So when the match starts, we will get x games at once. And as the games are ending, start new ones if the remaining games are less than the least number of required games to finish the match.
Example 5 wins match:
-Start 5 new games
-Player A wins a game. Score is 1-0. The remaining 4 games might be enough to end the match, so no new game started.
-Player B wins a game. score is 1-1. The 3 remaining games are not enough to end the match, so one new game is started.
-etc.


This suggestion is of course not suitable to the ordinary backgammon matches(with doubling, gammons and backgammons) which are planned.
