Explanation #10 (click to expand)
Red star + blue hexagon = green triangle.
Green triangle + red star = blue hexagon.
Green triangle + blue hexagon = red star.
The red star moves one cell to the right.
The blue hexagon moves one cell to the left.
The green triangle moves one cell downward.
Therefore, the correct answer is option 2.
Therefore, the correct answer is number 2.
Explanation #11 (click to expand)
The result of adding the shape in the first square to the shape in the second square becomes the shape in the third square.
Red star + blue heart = three green circles generated above, below, and in the middle of the reference shape.
Green circle + red star = blue heart,
Green circle + blue heart = red star.
When two shapes of the same color are added together, their color changes.
Red star + red star = blue star.
Blue heart + blue heart = red heart.
The red heart moves one cell to the left regardless of the addition operations in each square.
The blue star moves one cell to the right regardless of the addition operations.
Therefore, the correct answer is number 2.
Explanation #12 (click to expand)
The shape in the leftmost first square combined with the shape in the middle second square produces the result in the third square on the right.
The red circle and the blue circle disappear when they meet (a “+” relationship).
Shapes of the same color are added when they meet.
The shapes located in the bottom row (the 5th row) of each 5×5 grid remove one corresponding shape of the same color from the rows above.
The results of the first 5×5 grid and the second 5×5 grid are horizontally flipped (mirrored left to right).
Therefore, the correct answer is number 1.
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.
The type itself is not difficult, but it takes some time, so you must stay focused to avoid even a single mistake.
This kind of puzzle is not commonly seen online, and since it tests concentration more than creativity, I personally think it doesn’t perfectly fit the purpose of an IQ test.
However, it is sometimes used as a trap or attention-check question, so I decided to create one for practice.
🧠 How to Improve Your Mensa-Style Puzzle Solving Skills
Train Pattern Recognition
Practice identifying repeating rules across different shapes, colors, and directions.
Focus on noticing symmetry, rotation, reflection, overlap, and sequence progression — these five appear in over 80% of Mensa visual problems.
Think Like a Coder, Not an Artist
Try to “describe” each figure as a set of simple logical rules — for example, if A overlaps B, remove the edge, or rotate +90°.
The goal is to translate what you see into structured logic rather than rely on aesthetic intuition.
Use Dual Comparison Strategy
Don’t just compare horizontally (row-wise); always check columns as well.
Many puzzles hide their main rule diagonally, so practice scanning in multiple directions.
Slow Down at the Beginning
The first 10–15 seconds you spend decoding the pattern usually save more time later.
Rushing early often leads to misinterpretation of rules, especially when multiple transformations overlap.
Strengthen Visual Memory
Practice with short-term visual recall games — for example, memorize a 3×3 or 4×4 grid of colors for a few seconds,
then recreate it mentally. This helps you retain intermediate shapes and patterns without re-examining the puzzle every time.
Learn Common Rule Archetypes
Most Mensa-style puzzles are built on a few core transformation rules:
Addition / Subtraction of shapes (parts appear or vanish when combined)
Rotation + Reflection hybrids (mirror + turn effects)
Alternating color dominance (color inversion or cyclic order)
Positional shifts (movement along x/y or diagonal axes)
Logical “XOR” patterns — shapes overlap only when one is filled and the other is empty.
Knowing these archetypes helps you predict the rule type almost instantly.
Review Your Mistakes Intentionally
When you miss a question, don’t just look at the solution — reconstruct the logic yourself until the transformation feels intuitive.
This reflective step trains your mind to detect subtle rule combinations and prevents repeating the same error in future puzzles.
Maintain Calm Focus
Mensa tests measure not just reasoning but also emotional control under pressure.
A relaxed mind perceives spatial relationships faster and more accurately.
Practicing slow breathing or brief visualization before starting the test can noticeably improve clarity and consistency.
