Classic Trivia, developed by Make It So Studios, is a free, single-player trivia app, which offers classic quiz questions. However, in an effort to avoid multiple choice answers, the app provides players with Hangman-style blank spaces and a selection of letters to use for the answers. There are four categories to choose from: Science, Geography, History and Literature, as well as three difficulty levels. However, the 'Hard' difficulty and the full range of questions requires an upgrade to the paid version.
