some fun puzzles, some dumb (2+2=?), and some maddeningly unsolvable. I only got about halfway through in the 2hrs I spent, and found several that could have more than one answer (eg: 1,2, what's next? 3? No, it's 4! This an ACTUAL example, but highly simplified from their version - which was more like X, X+a, (X+a)+2a,?? but clocks). So it's not good as an actual test but still gets you thinking, and most of them are good. oh, and ":" means ÷ division & the handwritten 9 might be an 8 (in #28)

i found that when I'm ready to pull out my hair, walking away temporarily from a frustrating puzzle that seems to defy all the possible answers available that upon my return I would see things from a different perspective and eventually an answer. Although the one I'm on now has me questioning that procedure. Two round-trip walkaways and the only thing I have come up with, off the top of my head, was the remaining hairs. Both of them. I love to hate this app!!

Great app, good test, really enjoying it. I got near the end of the second to last level and ive decided to start the whole test again to try harder to get a better score, good graphics which keeps it interesting, the tests are not always straight forward so sometimes need to think out the box. Yes there are ad's but its a free app, the ad's only appear between questions and only sometimes. To the developer thanks very much.

Very challenging, i love it, i have one request thought, for some of the Math quizzes id like for worked out solutions because when i give up and ask for "answer" it give you a straight answer, i get curious as to how some of the calculation are worked out, maths is actually my weaknesses lol, other than that its a great app, theres little to no adds, honestly I haven't seen any in a while, and when it pops up, its not even 5 seconds, hats off 5 stars well deserved..

The game starts out fun but some of the solutions make no sense at all. I don't know how anybody in their right mind can come to outcomes that they provide for some of the more advanced levels. Still playing but finding it more and more difficult to continue due to frustration. So losing interest little by little. Enjoy!

there are a couple of errors. they also couldn't be bothered to correctly represent division symbols. the scoring is NOT accurate for IQ. the puzzles "sort of" get harder but there are several that are relatively easy that occur after hard puzzles. too many of these require guessing about what combination of numbers to apply what basic operation to. overall it's not terrible but it's a good thing it's free.

Really nice logic game. I got 138, could have been better (around 150) if I had shared it in three solving parts, 20 tasks a day. After 40 tasks the first day I noticed I had less patience to think about smart solutions and just went for the hints. Then the second day I solved the most difficult ones almost all with 3 stars. But solving all in one day can give you an idea on how long your brain can concentrate at max performance.
