Box tower-the balance mania

Time to show your building skills , make and take your tower of boxes high and high and high.....
Challenge is stacking the boxes without making it fall using your crane hook. More and more boxes you stack more score you'll get, each box you stack one score you will be rewarded.
Play until the boxes fall three times, and make your tower of boxes and your highscore as high as you can.
