Here you can play with 400 IQ questions which will test your brain power, providing a keen challenge to your powers of deduction. Spot the link between a series of digits. Solve the anagrams. Interpret the shapes and symbols. And also see how your general knowledge measures up. You can treat the questions like an exam, with eight formal programmes. Or just enjoy the exercises of getting to grips with the classic test of thinking around the corners.
