Review: HD version is better, but this was fun too

I downloaded this onto my iPhone Kindle app.  This is the black and white version.  The "HD" version is in color.  That certainly helps you when trying to determine the answer.  The black and white makes it tougher since you are looking for slight differences in the puzzle.When I say slight differences, I do mean very slight.  Little things like the order of the items, or 1 number off, or a smile versus a frown.Really a brain worker.  I enjoyed doing the puzzles.  I'll admit, I switched to the HD version after about 10 puzzles.  I felt a little eye strain on the black and white trying to determine differences.Once on the HD version, I was back to having fun figuring these out.It starts rather easy, and they get harder.  On the iPhone, there was a slight page issue, where the "next puzzle" button appears on the next page and not underneath the puzzle.  This is probably fixed by modifying text size, but I was too lazy to change it lol.  This ofcourse was easy to overcome by simply swipping my finger across the screen to the next page and then clicking "next puzzle".  If you get the wrong answer, it let's you know and you can go back and try again.  If you get it right, it has a short explanation on why you are right.Liked this, but loved the HD, so I would recommend the HD version.
