There is an unequivocal answer.
If you don't go into the maze of signs, the problem is simple - and it's obvious that it's the first square.
Tell me the right answer already. It's interesting, isn't it?
So you're right. I wonder if it's possible to come up with the same level 3 problem. It would have to be a mind-blowing experience.
I think it is possible to encumber the figures with additional features and on top of that to compose the figures in several rows into a solvable square matrix in a certain way, but you have to think about it.
I have a sneaking suspicion that this is not possible. So much for the challenge.
You can try for the simplest case in 3 variants.
So you're right. I wonder if it's possible to come up with the same level 3 challenge. It would have to be a mind-blowing experience.
Can you tell me in general terms why this is the solution? Is the problem solved by brute force or in some other way?
This is a reverse problem. The figure with the greatest number of common features is superfluous.
The figure with the greatest number of features in common is superfluous.
a figure with no distinguishing feature.
I think the first sentence makes more sense.
Oh, man, a circle has the smallest number of angles.
signs:
- colour
- size
- frame
- shape
all figures have two features in common. the first has three.
