When the outer edges of shapes of equal size overlap, all overlapping outer edges disappear.

Therefore, the correct answer is number 2.

Explanation #2 (click to expand)

Diagonal + Dot = Diagonal.
Dot + Diagonal = Dot.
Empty + Empty = Diagonal.
Empty + Diagonal = Dot.
Dot + Dot = Empty.
Diagonal + Diagonal = Dot.
Empty + Dot = Empty.

Therefore, the correct answer is number 2.

Mensa-Style IQ Test Guide

In the mid-section of Mensa-style IQ tests, problems often involve shape-interaction rules where one figure transforms when it meets another. The 30th question in the online Norway Mensa-style test is a good example of this. To solve such problems efficiently, pay close attention to how each shape changes upon contact with another.

Mensa-style IQ tests tend to feature relatively intuitive questions up to the late 20s, but starting from the 30s, problems that require calculation and logical reasoning begin to appear. As the test moves into the 40s, the questions often involve more complex and mixed rules, and this stage becomes the key point for time management during the actual exam.

To solve these mid-to-late questions efficiently, it’s important to familiarize yourself with a wide variety of pattern and logic puzzles in advance. In particular, focusing on problems in the mid-30s to 40s range of online Mensa-style tests is very effective for developing real test intuition.

According to testimonies from successful Mensa members, the exact passing criteria or number of correct answers has not been publicly disclosed, but it’s generally said that those who make only one to three mistakes tend to pass. Therefore, rather than simply solving quickly, it’s far more important to prioritize accuracy and careful reasoning.
