Is warball.io Safe?

It is a safe and fun site warball.io however there are really dangerous popup ads where you play a game to win a free prize. These fortunes are really scary. It lead me to this really unwanted popup with a strange address and said that i should spin to win. We all know its scam and its a virus. Besides, why would a website be called explicit dot something with a number or x. that has to be the strangest web address around here but remember never to click on ads or anything suspicious. Also, I have WOT on my side. Once I went to this really informal site i haven't trusted yet until i accidentally clicked on some hyperlink address and it lead me to ***** which is one of those sites that WOT gives a bad rating on. So I have to say warball.io is safe but some explicit fancy stuff are supposed to be dangerous.
