Copy the exact same idea of the game, the same style, and make a copy on the web (Facebook games actually did this and it was very similar to the mobile version), with a slight change in the paper distribution algorithm (such as BJ) i.e.: adding Provably Fair. In fact, my idea branched out into two, 1. Create a casino that pays for cryptocurrencies (based on the same idea of the game that I mentioned above), 2. The game remains the same, but with the Provably Fair addition as well.
Why? :
In fact, I love this game, and I have an account and I made some purchases in it (over $ 500), and what I noticed was before I paid in the game was making me always and significantly lose, but what I noticed after I upgraded my account to VIP, I was playing with real people who have Pictures in their account, while I own three cards (+4 which means that I will win without talking), and this was the first match after the purchase, i.e.: as a gift from the game (certainly not a coincidence), I see this is not a gift, but rather a fraud, so this idea came Mine.
Copying the same idea of other games and improve it is a wise decision
The idea of emulating other project games can backfire on the OP if the required measurements are not taking and the last time I checked there are companies that offer much different game services to gambling sites and it will be a wise decision for the OP to get the game through them.
vinca BK, Creating a gambling site is not an easy task and there's a huge fund involve but you need to mention what is it you really need our advice on.
but then you would have a hard time developing a system that can be trusted by people, unless you make your codes open-sourced.
Every casino I know didn't make an open-source code before they gain people's trust and what needed here is the Provably Fair with game seeds which will be used for verification. If all this is added the next steps are a campaign and other online marketing.
