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.
I don’t think this problem was particularly well suited to being solved visually. I should have drawn it with more care, but for some reason, ideas didn’t come easily today. Because the illustration is not visually refined enough, I believe it may have taken you longer to solve the problem. I apologize for that.
After solving several online Mensa-style tests, mainly in the late 30s to 40s range, I felt that the underlying rules were not as difficult as I had expected. What frustrated me more was having to abandon the familiar patterns and problem-solving approaches I was used to.
If you can quickly shift your perspective and approach problems from different angles, you should be able to solve most types of Mensa-style tests found online. These problems do not require lengthy calculations or extremely meticulous reasoning like physics formulas do.
If such problems did exist, I believe they would no longer belong to the Mensa test style, but would instead be overly complex logic puzzles of a different category.
Mensa-style questions usually rely on clean, unambiguous rules, rather than vague options or formulas that produce more than one possible answer. I find myself wanting to create problems that are just as clear and logical, but it’s surprisingly hard.

🧠 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.
