Update 6/18 - Nevada Gaming Board announced masks required at table games in Nevada.
I'll try to keep the body of the post updated. It may also help cut down on the amount of posts asking for this info. If this post gains traction, it may get a sticky. I reached out to the mods asking about putting together a post to collect minimums for craps tables in Vegas and other places. Keep it coming! If something changes, please let me know.
