A Scoreboard is a huge screen that is mounted on each stadium.
Hitting it will result in earning Scoreboard Points and activating an Offensive Skill.
Skills can be identified via the image that appears on the Scoreboard.
The location of the Scoreboard and the skill that is displayed is different for each stadium.

A Scoreboard that has already been hit will briefly be turned off.
A Scoreboard that has been turned off does not give points, and the Offensive Skill will not activate.
Therefore, the player who hits the Scoreboard first frequently may likely gain an advantage.
