There's a thread before that's named 'ending game' and that came from an Asian country. 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).
So that's how it goes? The first digits of the final score? Whoa. I really thought it was the last digit because of the word "ending". Turns out I was wrong.

Now I know.
Yes that's the mechanics on determining the winning number. So bettors can't be duplicated and there will be only one winner for each match.
The numbers can be doubled like 7-7 as given with my example. There's no way to cheat on the results because the score will be broadcasted everywhere since you are betting with the popular game, basketball.
