My Take
While this game serves a basic trivia game's purpose of fun and engaging, that is all it is. This app can be used as an activity for class but it does not encourage high order thinking. It just encourages students to race to answer a question for the sole purpose of being first. I've always said History is not a subject in which you just memorize different dates and names, you have to be able to connect ideas and give human experiences to those events. This game does the opposite. If I'm rating this app based on Bloom's Taxonomy, I wouldn't know where this app fits in as you need prior knowledge to play.
How I Use It
The game is great to engage learners but it does not encourage high order thinking.
