Have you seen this
https://www.bitcoincasino.us/games ? I just saw while trying to search some provably fair games. I don't think it has the pool or tongits but you will definitely find something new with their 650+ bitcoin games according to their website.
You are trying to search provably fair but what you found is not a provably fair casino site. Check the site again, do they have provably fair games or at least do they have specific page contains information of the provably fair system?
Sure they do not have it because most of their games are not provably fair as they provides games from 3rd party providers.
I have never seen any sites provides provably fair pool/billiard games, I'm not really sure about tongits game as it is the first time I heard about it.
Tongits looks like poker-kind of game.. . Or it's probably some kind of card game for some countries, like Philippines
https://en.m.wikipedia.org/wiki/Tong-itsOP seems to be looking for those he can atleast earn some profits. Most posters seem to be avoiding the profit part. I guess no one can guarantee any profit, reason why that part is avoided.
