It appears as though most (if not all) Microgaming casinos will stop accepting U.S. players on the 10th of this month.
If you enjoy playing on the Microgaming platforms, several casinos will allow players to continue playing if they are registered before the 10th.
I'd suggest that everyone who might want to play at Microgaming casinos download and register their accounts before the 10th of this month.
You can check out the main page https://www.nodepositneeded.com and see who is and isn't currently accepting U.S. players. On the 10th, there will be a lot of red on that page!
