There are two types of Boards in VDS. The normal Legends board, where your daily scores happen, and the Event Scoreboard, where Live Gaming Event scores are tallied.
During an Event, only the Event boards are used. Event boards will have some of the same Daily and Overall capabilities, but are also specially created to house any of the categories needed for an event.
They're also conveniently located nearer your Home Feed on your Home Page for fast access.
Event Scoreboards almost always have different content depending on the type of event, and the categories that are listed for them.
Here is an example of the Event Scoreboard button on the home page:
