World of Goo is an excellent puzzle game, available on most platforms—including PC, Android, and iOS at the very least. I played it on my Nexus 7. Basically, you build structures of latticeworks of goo balls in various different environments, trying to reach a vacuum hose with a minimum number of goo balls remaining.
The Good: The puzzles are challenging but fun. The graphics and story are professionally tongue-in-cheek. The physics feel right. There are lots of levels, divided into distinctly different parts of the goo world. Some parts of the world honestly made me chuckle.
Oh, and there’s a free trial version, if you don’t want to commit to a purchase up front.
The Bad: I honestly can’t think of a criticism.
The Augury: I predict a lot more fun with this on my Android devices. Highly recommended. 10 goo balls out of 10.
