Is there any reasons crypto.games isn't on this list?
Yes, I'm more familiar with "crypto-games.net" so subtracting ".net" the phrase become "crypto-games."
I just realized the site now uses crypto.games as its main URL.
Nevertheless, just like @Bitinity said, I've put it on #7
Well, perhaps the games are not very fair (maybe not more than 80% fair) because they are not decentralized or fully decentralized?
And the need to void/disqualify bets will be drastically reduced on well decentralized betting system. 
Well, that's how the mainstream slots have been set up. Don't use it if you don't like it. Unfortunately, most of the best-seller title didn't use provably fair when we can verify hashes.
Anyways, I'd rather encourage new developers to implement provably fair than to ask big players to change their way of doing business.
One vote for Bitsler
I'm impressed with their new "indie" slot as well.
