Ah, so 'they' are 10 games away. I get it now, thanks.
The number of games they'll play will depend on their performance. The main event is structured as a double elimination tournament, and most of the matches are best-of-3. If EG wins every single game they play, they'd be done in 9 games. If not... I think it could be up to 20 or so? It's complicated. :)
And, as it so happens, they ended up playing 13 games in the main event. And Sumail is now considerably richer. :)
