Today's Free App of the Day is World of Goo
Originally $1.99

Today's Free App of the Day is another of the 40 free apps that have been available since yesterday. This was previously the Free App of the Day on December 24, 2012.

It is an award winning physics-based game with attractive graphics. You must build a structure to a pipe so that a specified number of your little goo balls (you also use them in construction) can climb up the structure to the pipe. The goal is to use as few goo balls in construction as possible as you get bonuses for goo balls over the set number for that level. I really like this game--and it gets quite challenging. It's a good repeat as a Free App of the Day.

709 of 844 reviews are four stars and above.
