Trivia Troll University's curriculum consists of ten academic subjects, each of which consists of ten jigsaw puzzles which are appropriate for the subject matter. Your "assignment" is to answer multiple-choice and true-false questions to earn the pieces of the puzzles. Your next challenge is to assemble the puzzle not knowing what the picture is. When the puzzle is complete you'll see a brief description of the picture.
This is a great app to test or improve your knowledge of academic categories. The questions are challenging and the jigsaw puzzles are fun. It's free, so what do you have to lose!
