As far as i know, you can play directly from wallet in luckybit. You just need to copy their address and send it amount which they needed to play/gamble. They have plinko games, so once your deposit come thru them, you can watch your bet
I do no think it is the one asked by OP. As per my understanding, OP is looking for a site where he can play/login using his wallet. There were some sites uses this kind of feature but most of then are ethereum based gambling site where users are able to login using metamask. I myself prefer to avoid such sites because I prefer to use common site where I need to send deposit first to my account instead of connecting my wallet to a gambling site.
