Hi MaryAnn.... - welcome to the forum!
There are no known viruses that can infect the iPad - Apple's approval process for allowing apps to be sold in their store is stringent, plus the device's iOS is 'sandboxed' meaning that apps are contained w/i their own space (think of a prison cell). Also keep in mind that malware comes in many forms (viruses, worms, trojan horses, browser hijacks/re-directions/etc.) - a virus is a type of malware that can replicated itself and spread to other files - just not possible in the stock iPad.
As already stated, the game downloaded re-directed you to another site - deletion should be enough. Interestingly, I was searching the web in response to your question and found
THIS LINK about an app game called 'Simply Find It' which contain a harmless Trojan Horse, SO who knows what the future might bring - at the moment, you should be safe - BTW, what was the game you downloaded - just curious? Dave
