BoxUp & Friends is an award-winning and highly addictive game and It’s a nice choice to kill time on your phone when you feel boring, you just need to choose playing type "with friends" or to play single so you can go with a lot of amazing levels. The play with friends mode is quite nice which enables you to compete with others in 2 minutes to see who can reach the highest. Moving boxes is very easy; you just need to drag cool boxes over each others to get the highest meters and if you with to rotate the box just touch it, but if you want to return the box to original place you just need to drag it on others boxes and it will return back, but be aware!! you have to be balanced to keep going up and up. Its fully real physics so be accurate where you are but the boxes and sure that physics and simulation lovers will fall in love with this game. The game is very simple to start but needs some skills and practices to handle. Sometimes you will feel quite frustrating if you almost reach the height but the boxes all fall down. and you can watch a demo video here http://www.youtube.com/watch?v=uvbDF5L-x6w
