I think many of us who have smartphones have tried out the addictive touch screen game 'Unblock Me'. In this 2D game, there is one red block surrounded by a number of brown blocks in a box. The purposed of the game is to move the blocks around in order the free the red block from the box through a small opening in the side.
I have had some fun fiddling around with this game and at times have gotten a bit frustrated, but I realized that this simple game has some lessons we can apply to life....
