Honestly I don't completely believe in podcasts like that, I mean there are some parts that are exaggerated so that the podcast looks more interesting, for example, if you want to see the original and fake versions, we can see on Higgs Domino similar but not the same. Besides that, the features are definitely different replays, win records and more, I'm not sure there is a similar game without a license moreover they won't be able to clone every game which is continuously updated.
You can search for the mobile game Royal Domino (not found in store), a slot game adapted from various providers, such as PP and PGS. The version shown is identical to the original, except the betting model has been changed to in-game coins. Not only is this similar, but it seems there's a way to use the original slot game across multiple platforms. I don't know where they got it, but they probably purchased a license to use it or in other legal or illegal way. However, if they do use a license, there's no information about whether it's licensed by Pragmatic Play or any other provider.
well congrats for your max win.
