15 Numbered Rolling Cubes Puzz

Remember the famous 15-puzzle? Well, this is just a variation that consists of a frame of numbered cubes in random order with one cube missing. The goal is to order the pieces from 1 to 15, left to right - top to bottom. But there is a twist: You have to order the cubes by number, color and orientation…. Wow… this looks like a challenge.

In the easy mode you only have to order by cube number and orientation (color does not matter).

A picture is worth 1000 words so you better look at the images with the initial and final positions. Did you get the idea? Can you solve it? Then why don’t give it a try and have some fun.
