Hi,
This seems like an interesting project. I have been working for online casinos for the past 5 years and I can provide you a good solution with the most popular casino games (roulette, blackjack, video poker, slots, etc).
Please let me know exactly which games you would need and what would be the timeline of release.
The games are usually connected to the server side so all the outcomes are generated there and not on the client.
Best,
George
