Flat Cubes: a 2D Rubik's Cube comes from Christophe Scholly. How many times have we seen puzzles described as a 2-dimensional Rubik's Cube"
  The object is to slide/transfer the colored tiles onto their targets.

Interesting: not all the rows/columns can slide.  Only the ones that have the black borders can slide.
There are 100 levels and I solved the first 25 in about 30 minutes.  Last night I solved the next 40 levels in about 45 minutes. 
If you've never done this type of puzzle, then definitely give this a chance. The graphics are really very polished.
