If I understood correctly, then there is no issue.
you create just one board, so all player will see the same. Then using Verse UI you can display different question independently for each player.
So basically anything 3D is shared and 2D is per Player.
I would assume you want them to answer different question but all at the same time, so in the board after moving the pieces you can make a general sequence to transition to the question and then display a UI with the question and the different answers with a timer. When the timer end or all player already responded, go back to the board, move pieces and so on…
