There's a thread before that's named 'ending game' and that came from an Asian country.
That was not popular all over the asia, it's only popular in the Philippines IMO.
The mechanics of the game is it will depend on the ending score of a basketball game and that could be an NBA match or your local basketball league.
If the final score is 98-79 then the ending result will be 9-7 (97).
The mechanics is so easy but for those who have access in online gambling, I don't think they will choose this type of game compared to sportsbetting.
