I do not have any of those written down, but I could do it ( I'm just not gonna waste a lot of time knowing someone may sell it to you meanwhile ), so instead of selling you a previously made casino game I offer you to tell me HOW you want it to be and/or look and I'll do it for you and give you all the code etc...
This way you won't have a bunch of games all written and looking different but a well-formed pack of all 5 games they way you want them to be.
I've got more than 3 years of experience with Unity and C#,
hit me up if you're interested!
