this is a good visual puzzler,and while a few of the layouts appear to be the same shape, the color layouts make you really think on what goes where. good as a casual game. as for ads: they are done fairly well. auto muted, but not always happening after every level. if you don't have service or have poor service, the game just keeps going, no pause to wait for the ad service to get an ad. would recommend as a fun little puzzle game to anyone who doesn't have any color perception deficiencies.
