Like the comment underneath your post suggests, I don't want to include casinos that have negative tags for valid violations. Even though the feedback for DuckDice was written back in 2017 and some users who initially posted a negative rating revised their trust to neutral, I still don't want them on the list.

Simpledice doesn't seem that popular on Bitcointalk, but that isn't necessarily a bad thing. They aren't negatively tagged, so I will take a look at their offer with the next update of my OP.
