Someone said in a random WA group that these are from one of the free online Mensa tests. Exact source unknown. Nobody seem to be able to figure out solid rules, so I thought "Hey, maybe Puzzling is the place. Seen a lot of brainpower here." Any takers?

1 Answer 1


Partial answer:

For the second problem, the answer could be:
enter image description here
In each row the figure seems to rotate $90^\circ$ clockwise from each column to the next. If the figure doesn't have a central dot, a dot and a black semicircle are added. If it has a central dot, the dot and a white semicircle are removed. If we apply this to the bottom row, the last figure in that row becomes the one above.
