I don't mind having to watch ads after a level but having an ad placed right snack in the middle of a level is quite frustrating. Very, very, very frustrating and annoying...UPDATE. 1 STAR. Now, during the game it will pause itself and then make me have to watch an ad once I hit the play button to try and resume. I can be right in the middle of matching an item and it pauses. Game could be great but it's too many barriers for me to continue playing. Have uninstalled.
