Foldology 2 - Master the Folds is the first sequel/expansion to Foldology. Playing the game is simple: tear out a puzzle, then figure out how to fold it so that the picture is put back together, making a neat 4x4 square. It is meant for those who have completed Foldology and crave more puzzles, so these puzzles start at a higher difficulty compared to the original game. There are 100 brand new and unique puzzles to work through in this expansion pack.
