Do you roll dice behind your DM’s Screen or in front of your players?

Masters @ChrisPerkinsDnD @JeremyECrawford @mikemearls do you roll dice behind your DM's Screen or in front of your players? Regards.

I do both – most rolls behind, but important or dramatic rolls I do in front of the players. https://t.co/7oKNzsD8Vu
