There are books on how to build altcoins but I don't see any in-depth guidance on how to build a gambling site.
It seems to be all trial and error.
If you know of any technique or site or forum I would appreciate hearing about it.
Its basically the same as building a website with the scripts related to gambling,I am not good at these aspects but there are lot of courses related to developing options so you need to learn that if you want to build a gambling site.
