Dr. Mario World is, in many ways, perfect for mobile. It's a colour-matching puzzler, one of the most popular genres on mobile. It's shares DNA with Tetris, the original portable gaming classic. Plus it's from Nintendo and, well, everyone loves Nintendo.

You'll find download links for iOS and Android in the About section of the video, so if you want to play doctor yourself, you know where to go.
