SEQ 4+

Contrary to other mediocre to negative reviews, I think this is a pretty good puzzle game. Yes, the puzzles in World D are still relatively easy for a 22+ year old because they are listed as only medium difficulty. The puzzles do actually get more challenging as the worlds increase and within each world, i.e don’t prejudge the entire world’s difficulty by its first or second puzzle. Additionally, if you’re the type of person to seek out a puzzle-type game involving sequences of numbers, you’re probably the type of person who has the analytical mind necessary to successfully complete these puzzles. So, don’t assume just because you find them easy that an everyday Joe without your mind will. Perhaps you are more special than you think. Also, the techniques (paths) you learn in earlier puzzles (when there are multiple solutions) do help later for the more difficult ones. Therefore, if you’re reading this review, my suggestion would be to consider downloading and playing it. If nothing else, it’s a way to pass the time when waiting for transportation or in your doctor’s office. 🙂

Glad Starbucks offered this game as a free app, because I'm really enjoying it. It's definitely challenging at times, but not to the point where you want to give it up entirely. You can step away from it when you need a break, but you want to keep coming back. Very satisfying when you solve a puzzle, so that it keeps you going; it's self-contained (in that it doesn't require in-app purchases or playing with other people to make it work properly); and it definitely makes you think!

I refuse to believe that I am so smart that I am the only one that finds this game not much of a real brain workout. It wasn't until sometime in World D that puzzles even took more than a few seconds worth of thought. Since many of the puzzles have more than one solution, one could almost "wing it" and just try multiple paths.
I was complaining to my daughter about being bored with it and ready to give up and put it away for book when she said, "Let me try." She is 22 and had never seen it before. She immediately solved a World D puzzle. I can use the memory for some other time waster, so this one will be deleted.
Pluses? Didn't crash and decent minimalist graphics. (Minimalist is the buzzword for apps now in case you've been asleep for the last two years...)
