so what make this coin diffrerent from other poker and gambling coins ?
Did you read the post, just 2 above yours? Let me sum this up for you:
First of all, jl777 says he has solved most, if not all, problems that have prohibited the development of any decentralized poker platform in the field.
On top of that, you can anonymize your winnings by using JUMBLR. So, suppose you win a big game of poker, you jumble your winnings and no-one has proof that your btc or kmd or whatever coin is popular by then, were won with gambling. This is quite huge, since there are a lot of legal issues regarding online poker, not only in the US.
It is the first coin to actually make good use of the Lightning Network. Just check this issues list to see the help LN gets from jl777:
https://github.com/ElementsProject/lightning/issues?utf8=%E2%9C%93&q=is%3Aissue%20author%3Ajl777%20It is a Bitcoin fork, and does not use Ethereums smart contracts, like a lot of other gambling coins do.
I'm gonna say it: It's a game changer.
