This is not a puzzle game, but a money making machine. I had to watch annoying ads after every level, and sometimes they would get stuck and I had to close and relaunch the game. I made it all the way to level 40 and nothing much changed, same boring and unchanging level designs, which tells me that this game was only made to show ads and annoy you enough to pay to remove the ads. Google should remove games like this. This is a shameful disgrace to the mobile game community.
