Keeping up with the game shouldn't be an issue, but in the event that you do behind, there are numerous tools to bring the game state back up to speed in mere seconds.
Overriding the Game Clock
Scorekeepers may manually advance from one quarter to the next by simply tapping on the clock in the upper left-hand corner of the scoring screen.
Overriding the Score
To manually adjust the game score, open the Game Menu > Manual Override > Adjust Score.
Simply tap on either of the team scores directly from the scoring screen.
Note: The game may also be reset entirely through the Manual Override option within the Game Menu.
