The issues i see in case of Mr. Siemdagmaer were:

1. Failure to provide complete details at the time of account restoration.
2. Kept on creating multiple accounts when the first thread itself had received a reply. (Unnecessarily trying to force an action).
3. No knowledge of receiving his funds back in his wallet. (Even after getting the transaction proof, he enquires what he can do now, which is totally irrelevant).

To me all sites are rigged when I am losing a lot and legit when I am winning a lot.
So that's an observation based on personal experience.
Normal human tendency is to see fault in others before reflecting on self.
My understanding of scam websites is simple. Those who do not give any withdraws at any time. Otherwise they are legit.
And Luckygames surely fits in the legit category (100%) because I personally have withdrawn a lot more than the amount I ever deposited.
and am still doing it periodically. And I have been on the website for 575 days since registration now.
