If you don't like to log in your Bitsler account or in the Bitsler forum or even check here in Bitcointalk for the announcements for new promotions or contests, you can create a google alert where all you need to do is create a search string and create the alert within your gmail account and just wait in your email, they will send you an alert if anything is posted in the internet about Bitslers new promotion.
Example of gmail alert search string that I use is Bitsler+new+promotion+2019 and select "as it happens" so that anytime a new post is created, you will be alerted.
Now I just know that this is possible, thanks for this tips and tricks. Gonna try this also so its easy for me to get notified about the new promotions.
Does it support floating notifications on mobile? What I'm doing is adding shortcut to my homescreen, one click-go-and-play.
I guess it does as long as you allow your Gmail to show notifications then its good to go (it shows up in my iPad), however, I think if you allow that to happen, even non Bitsler related emails that you will receive will show up since there is no function or feature to filter out what will show up in your smart phone screen.
