I just checked the site and it is definitely not a legit site.
If it was than their minimum payout wouldn't be BTC0.03. The minimum payout of this site is unbelievably huge.

I think their intention is to earn some quick money from the offers completed by the users. That's All!

Those who will play in the hope that they will receive payout at the end will be very much disappointed.

YOU HAVE BEEN WARNED!
