It's a fun app for maybe half an hour but after that it's just not fun. The ads are a bit annoying, but it is a FREE app (for the most part) so I understand the point of adds. Also I think there should be more patterns. Lastly, for one hour I have been playing this game, and so far I haven't found a SAVE button so I can save my work. Overall i think I you have younger cousins, sisters, brothers. And for parents, children. I'm sure they MIGHT take an interest in this app..
