If I have to create one it would be like Yobit Dice, its simpler than any other I've played with. Other than being simple is that altcoins can be played which is quite a good option for the users who hold altcoins. But then again its not possible to just create a dice site for altcoins when its also not an exchange site otherwise those altcoin holders aren't going to stay.
I think this is one of the great achievement of Yobit Exchange.
I don't even think somebody is playing dice on YoBit. If anyone wants to play dice, they'll go in a dice site instead of playing in an exchange site. An exchange site is designed specifically for exchange. The dice games even lack options like autobet, etc. It's just a small portion in the whole YoBit website.

Nope. There are gambling sites like Betcoin that accepts altcoins but is not an exchanger site. You see they have a quite popular gambling site. Not everyone that's gambling in altcoins are altcoin holders. Besides, it's not that hard to transfer your gambling funds to your exchange site altcoin wallet. It just takes a couple of minutes to do so.
