I can confirm that I dont received this particular update and probably the reason why I didnt received the subscription bonus this time.
Stake already sent an update about October monthly subscription bonus stated that Im not eligible for now which means other players already received their bonus.
Im active on Stake ever since I subscribed including playing on the games that listed on the screenshot you sent. But I think this time they distributed the bonus by batch per week.
Unfortunately so far I haven't heard any reason why some users didn't get the email update for October subscription and a little information, those who have received the update email will not necessarily get the bonus because there is still another selection process. Today Stake team sent another email regarding October subscription while recommending 2 more games to try and I don't know if some of them have already got this bonus or wait for next week.
From the screenshot below I assume that I did not receive the bonus even though previously received the update email or another option they still monitor my activity through 2 new games suggested.

I see. I received too that specific email so I believed your right about the qualification for the bonus is not based on who received the email or not.
Hope we are on the next batch but I definitely avoid the Tarot. I tried it and its so hard to win. Id rather play Big bass halloween slot.
If anyone wants the full 60+ page court document, feel free to contact me and Ill share it.
Well, this thread is dedicated for Stake.com players while Stake.us is already a separate casino which user here is not affected.
