2x2x2 & Slide Cube - Magnetic Sudoku Version

The magnetic speed cube combines two styles of puzzles into one.  It is not only a 2x2 cube, but also a sliding pieces puzzle. 

It solves like a standard 2x2 until you remove the #1 tile on the white face. After that, you can turn, slide, rotate, and replace your way to a solved state!

The goal is to have 1-4 in order (and properly oriented) on the correctly colored face.
