Cannot close the ads – Mahjong Dimensions 3D Review

I'm unable to exit the full screen ads. Once an add goes full screen, there is no "x" button to continue play. Even if you click on the ad and return to this app, the ad is still at full screen. Force closing the app will return you to the beginning level. The game is fun, so I couldn't give it just one star.
