I frequently get games popping up in adverts on my phone and sometimes they say they will measure your IQ?

I just played a game where you ‘unscrew’ bolts that hold a building together. You have to rotate the building in 3d to find the bolts, and also you have to chose the correct colours to remove so that they slot into three matching coloured holes at the top of the page.

I started and kept going to the end, when the counter for IQ got over 120 I was surprised, but as I removed the screws it kept increasing (it didn’t get more difficult). When it finally got to 600 at the end of the game my scepticism peaked!

Silly game, just a test of hand eye coordination.
