I don't think I fully understand your questions.
what I want to talk is how to make the gamble fair enough.
Why? Some sites are provably fair, some are not. If you want to be sure that you gamble in a fair way, only play on provably fair sites.
as far as I know there a lots of dice site , and they can be proveble fair.
You've answered your first question...
and any other examples of new type of games ( gambles)?
What are you asking here exactly? You want to know about more unique ways to gamble? Custom games maybe? I really have no idea what you mean by this.
