I still found such kind of game here, actually i found them often here now, although its not about bitcoin only but other crypto with faster confirmation. The issue on this kind of gambling is not the provably fair its the reputation of the website compare to those licensed one. I found them too suspicious and too risky actually.
I played before on gambling site that is like that I think it was TRX network related gambling site, I am not sure but I think the game is rigged as I have played the dice game with 80% chance of winning but lose 8-9 streak consecutively. Although it is possible but I think something is not right on the site, or I am just unlucky. I forgot the name of the site.
