The point of it

I actually like the fact that the correct solutions are not shown or explained or even indicated in your answers. I am aware of the questions that I do not have a correct answers for. I guess that what makes us different is the ability to recognize the patterns and extrapolate. The language portion is pretty easy and English is not my first language.

I should mention something to those who criticize this as "not a valid IQ test." You're right, and it's not meant to be. It's meant to be a fun logic puzzle game, which allows you to practice verbal, spatial, and quantitative reasoning in a way that does not give anyone an unfair advantage when actually taking an official IQ test, such as the Mensa entrance test. This is why they call it "brain test," rather than "IQ test." Just have fun trying to figure everything out, and see how high up on the score board you can get. Try to find new efficient methods to solve problems that you already know the answers to if you figure everything out (btw, it is incredibly time consuming to figure out every answer, so that is a challenge, in and of itself.) Just have fun, and always take an imperfect score as a positive experience, as it allows you to discover new ways to improve your logical reasoning.

Useless and Unrealistic

These questions are very disimilar to the actual mensa test. The questions, in particular, finding the next number in a sequence, are frustrating, because they are not that complicated on the actual Mensa test, and there’s no rationale behind which pattern they’re choosing. They set them up in a particular way and you are left to try a million possible variations of equations (prime numbers?, multiplying?, subtracting?, divining?, a combined?, and finally one that had you add the first two numbers and then subtract the third number, but with the digits reversed...really?!) and hope that you find the right one that lines up with their logic. That’s not measuring your IQ, it’s just hoping that you get lucky and figuring out what kind of zany pattern they’re coming up with. There are literally thousands of possibilities and you could spend all your time going in the complete wrong direction. Very poor test and completely unrealistic to Mensa standards.
