I certainly understand the need for ads to support a game, but this is ridiculous. Not only when you first start a game, but between EVERY round of the game, there are ads with TIMERS, sometimes 3 different ones you have to watch before you can start another round. For every 3 minutes I spent playing, I spent half again waiting for the ads to clear. There are lots of other Mahjong games out there! Bye@

Thanks to Google, I will be uninstalling this app. It seems they are obsessed with an ad for Norton Airgas that runs across the bottom of the screen as I am playing. It LOCKS UP my game. I report to Google that the ad is not appropriate and plays too much, but it replays IMMEDIATELY making it impossible to play my level. One level took over 5 minutes because of the delay caused by this ad being running. None of the other ads cause a problem like this.

I've enjoyed the game, but once you cross the 40 level mark, it does not display the results of individual games past that... so if you scored 2 stars on a game, you can't go back and do it again because you have no way of seeing it or selecting it. This means the most challenging ones are a one time attempt, disappointing.
