As you can see, I've spent a lot of hours in WoA.

TL:DR If you enjoy putting together physical puzzles, then I'm confident you will enjoy WoA as well.

Actual review:

I have tried many jigsaw style puzzle games over the years. Most of them weren't that good and didn't have puzzles that I wanted to put together anyway. Usually the puzzle piece manipulation system of those games felt awkward as well.
WoA excels in all of these areas.

PUZZLE CHOICES: An incredible amount of images and styles. Unless you positively hate paintings, for some reason, I'm sure you will find many that you will want to put together.
For difficulty, you have a choice of 12, 48, 108 and 300 pieces for any of the image choices.
If you have the 3D DLC, you can choose 3D and puzzle piece rotation on/off as well.

GRAPHIC QUALITY: Fantastic! These images are just as clear and distinct as any that I could find online for the same individual painting. Its easy to see colors and discern details in the paintings. So there is no muddiness or blurry images. Its no harder to put together the puzzle than it would be anyway.

IINTERFACE: Simple and straightforward. Many features can be toggled on or off to suit your preferences. As I mentioned above, very much like working a physical puzzle.
You can bring up the original image, for reference, any time you want. WoA comes with several puzzle background choices. Or you can create the color you want. Your own background images can be added as well.

PRICE: So reasonable that I find it hard to believe.

DEVS INVOLVEMENT: They are very friendly and responsive to suggestions or questions. Very much appreciated!

DLCs: There are a couple of related DLCs. A 3D version and a paint by numbers version. I enjoy those too.

These are just some of the reasons why I like and appreciate this game so much. Working on a puzzle and listening to music is so enriching. Because I am spending longer looking at it, I see details in the painting that I wouldn't have noticed normally. The same goes for the music. BTW, there is a feature to play music on your device. WoA comes with some classical music. You can play that or your own files. That also works seamlessly.

As to Learning, I have already discovered so many artists and paintings that I didn't know about before. Many that have become favorites. Much appreciated.
