Never heard of that site. I play lotto at crypto-games.net. You can try it. Their lottery is legitimate and uses third party to pick winners and all the records are public. Btc Lotto is usually active with a decent pot twice a week and during wagering contest the pot goes even higher. Give it a shot.
Thank you for your recommendation, because I have some XAGCs to try, I just want to know the fairness of this game.
