Worst possible download ever

When I open deer hunt a pop up lays over the game screen. usually ads can be dismissed but instead it directs to App Store to game called "slot oz".I got the deer hunt game for free to try out but I cant get passed the "slot oz"pop up. I deleted the game. Oh it asks to rate well lowest option is 1 star which is higher than I would rate it.
