Very fun, always a challenge, plus calming colors.

I got this app for free from star bucks a few months ago and wasnt expecting much, however I know as a developer, Starbucks only picks great looking apps that also perform well for their free ones.

I play this game when I am cooking, riding in a car, or just waiting in line. Its addicting but not annoying about it. Meaning you arent getting all of those notifications "that you need to come back now" or anything like that.

Id really recommend it if youre looking for a great simple puzzle style game.
