The lights are on and the crowd is about to get crazy as the final showdown is about to start...
Because it's on Stadium that the last match of the solo mode is taking place.
It's a large court with points being dispatched in a unique way: the red 5 points zone in the middle is very small at the start of the match but increases in favor of the player who is behind on points.
When the said player scores either a 3 or a 5 point goal, the opponent's red zone resets to the minimum size. So if you are way ahead, you might still want to take a 3 pointer before the end of the round so you don't start with a maximized 5 points zone at the begining of the next round.
This feature adds tension and a bit of strategy especially compared to Lawn. Beginners often like Stadium due to this apparent comeback mechanism.
