Summer is the sunniest and merriest time of the year. And while it’s still cold, you can experience the warmth and fun of a summer day playing Sand Balls! Your task is to dig tunnels in the sand and help the colorful balls to get into the trunk of a big toy truck. At first it might seem easy, but your mission will get ever more difficult with every level. You really need to use some logical thinking if you hope to succeed. Once all the balls are inside, the truck will be able to depart with its cargo.
