An new game for you: Sand Balls from gaelic's blog

Sand Balls is a fun and addictive sand drawing game in which you must guide all of the balls to a box. 
To clear each level in this fun free online game, you must dig through the sand and make every single ball fall all the way to a charming, heart-shaped box.
On your way to the bottom, you'll come across a variety of obstacles, such as spinning planks that scatter the balls or stationary boards that catch them.
To boost the number and set a higher score, grab all the white balls by just making the colored ones touch them. Just don't forget about those priceless balls!
