Dice aren't assigned to players in this game so even if they were ridiculously biased it wouldn't give any one player and advantage, even if you did roll them more than 3 times in the entire game.
Yeah, I’m surprised this didn’t get a low impact. If just setting initial board state isn’t low, what is?
Maybe a player can learn which dice are biased then choose those dice to throw depending on what result would be best for them at that moment? So they gain a slight edge.
No, you don't choose dice to throw. The dice are all thrown and then you choose.
