I am downgrading this game to 1 STAR today solely because of the ads. Every free game has to show ads and this game is enough fun that I put up with them until now. You can close a lot of the ads by clicking a VERY SMALL x that appears in the corners, if you can find it. They are devious with the placement and coloring of the x, as most of the time they are almost the same shade as the background they appear over. Today though, a very annoying audio ad that won't close without many taps started.
