Lemme give you the rundown. (for the new players looking in the comments for help)
These "instances" are just different games of pong that both add to your points. You have to buy the "more instances" upgrade in the shop (an arrow will pop up afterwards)
if you want faster wins, set the win points lower. If you want more points, set it to max.
