IQ puzzles on youtube

Here is an example of a series of tactile matchstick IQ puzzle tests by APPUSERIES on Youtube.

These are the sort of Questions found on IQ tests, and the question and solution are all provided in the one clip.
These people (with Indian accent) have many many educational clips on Science, English, Mathematics and more.
Many items are subtitled which helps with learning to read or overcoming the accent issues. I dont find her difficult to understand.

I enjoy very much those kind of puzzles. Nevertheless I will have to wait for my grandson. At what age do you think they can work a puzzle like his one?

Excellent, love this sort of stuff. I showed it to my boy and he was fascinated!!!
