Casino Game Source Code Acquisition

I'm in need of existing casino games source code, covering slot games, card games, and roulette, along with live games. The source code should be compatible with Next.js and Node.js, as these are the preferred programming languages for this project.

Key Requirements:
- Source code should not be from an API but directly from the games.
- Backend inclusion is necessary for seamless implementation into our sites.
- The need for the games to be existing ones, which can be quickly deployed and tested.

Ideal Skills and Experience:
- Expertise in Next.js and Node.js
- Proven experience with casino game development
- Ability to deliver comprehensive, backend-inclusive game source codes
- Strong understanding of slot games, card games, and roulette
