in this case it is clear you don't really know how bitcoin works and yet to planned to run a gambling site? unconfirmed inputs doesn't mean double spend idiot. don't run a onchain gambling site if you don't know what could you face, unconfirmed inputs are not means of cheating. you even gave a link explaining what is unconfirmed inputs but did you even read it?
unconfirmed inputs doesn't mean double spend
