If I understand you wish to create something like CoinPoker?
https://coinpoker.com/They operate for two years already, but still they are far from popularity! Unlike you they had many promotions, you can find their coin on exchanges...interesting project in the beginning, I thought they will make something more in crypto poker world.
Well look at the crypto poker in general, they are not so popular yet! Sadly, but look at some topics about poker here and you will see.
