On my DEV server, after a user finishes a game on the website, a semi-transparent overlay covers the whole page. The score is then shown on the overlay. Through the overlay, you can still clearly see where google advertising would go. There is no way to accidentally click it. In fact, the advert is not clickable until the overlay is closed (and it is not possible to accidentally click the advertising when clicking close).
I've read the Google Adsense Policies and suspect that I am violating the following policy
Google Ads may not be:
Obscured by elements on a page.
The picture below shows you the overlay and advertising.
It seems the answer is pretty cut and dry, but I'm weakly hoping that by obscure they mean you can't see the advertising at all. Anyway, I'd like to see what other peoples' take is on this. As you can probably guess, for aesthetic reasons I'd really like to leave the overlay in place.
UPDATE: Just to be clear, I'm not using "Adsense for Games". I'm using the Adsense meant for websites.
