I tried to play the Rising Star game ...
It's probably that I just don't know how to turn on popups in Brave browser, I looked everywhere in the browser settings, I just can't find it. It did show some cards, but I never seen any pizza box card, nor a coffee cup card. I even bought some cards on the market, but although it said I payed for it, I haven't paid for it, and I didn't get the cards.
In other words: I can't get it to play. Not on a PC with windows and Brave browser, I couldn't. I know, if I'd want to complain about it, there's a group for that. But I'm not complaining. Just a notification, I couldn't get it to work for me.
