▲ ▼ Prevent arguments related to scorekeeping
For anyone who has played football, basketball, badminton, or spikeball etc. - you would probably have a good rally, or long passage of play and then when someone does score, everyone seems to have a different interpretation of what the score was/should be.
It's a bit annoying to argue over something so simple. So there should be some kind of scoreboard app that's easy to view and update without disrupting the flow of the game.
