I downloaded this game because the aesthetic style gave me the impression that it would be like Nintendos Brain Age series or Luminosity, where the user can expect some sort of psychological development by playing the game. The clean, clinical aesthetic brings to mind a crack team of neuroscientists tasked with designing the game around proven techniques of psychological development.
The instant I downloaded the game I realized that this visual style was mere effrontery. The rate the game presents you with questions is too slow to be properly engaging. There are screens you have to click through between every question that try to appear as indications of progress but are obviously just bulletin boards so the game can barrage you with ads. I prefer the rapid-fire style of the pawn stars trivia game it is a much more engaging form of presentation and content delivery.
Based on design and layout alone the game gets three stars but I subtract an additional star because the quality of the questions is low-tier. From a scale of 1 to 10 I give the game a 5, with 1 being trivia crack and 10 being Rick Harrisons Trivia Challenge (the absolute gold-stand as far as questions that reward deep knowledge and critical thinking that I hands-down fully endorse, with quiz up being a close second). With this game there are simply too many soft-ball questions to appeal to the lowest common denominator, instead of doing what Rick Harrisons Trivia Challenge does which is asking questions that are interesting and easy to guess but not common knowledge.
TL;DR: As a trivia game enthusiast I would say this game is better than Trivia Crack but leagues behind Rick Harrisons Trivia Challenge, Sporcle, and Quiz up.
