The puzzles are not good
The puzzles in this are no indication of a true IQ test. Mostly trick questions like "choose the biggest number" (with one number bigger in font size than others), or which way is the torch light facing (no idea wth this means even after seeing the answer). The app relies in ambiguous grammar and vocab in emEnglish to trick you. Stay away from this.
