How to play Reasoning Challenges
Challenges are reasoning puzzles across 60 levels: figure matrices, rotation, number series, logic and words. Each level is one question similar to the practice ones; get it right to earn stars and unlock the next.

The rules in 3 lines
- 01
One question per level
Read the question, look at the figure or the series and pick one of the options.
- 02
Wrong? Try again
The wrong option is crossed out and you pick another. The explanation appears when you get it right.
- 03
Stars and levels
First try with no hint is worth 3 stars. The next level unlocks when you solve the current one.
How to play
On your phone
- Tap an option to answer.
- Hint crosses out two wrong options (once per level).
- After two mistakes, Show answer appears: it shows the right option and the explanation.
- The “Level” button at the top opens the list of all 60 levels, with the stars for each.
On a keyboard
- Tab moves through the options and buttons.
- Enter or Space picks the focused option.
- Esc closes the level list and the “⋯” menu.
Step-by-step example
A simple example made up for this guide (it is not a question from the game), of the number-series kind:

The stars tell how you got to the answer:
First try
One mistake or hint
Show answer
Beginner strategies
- Find the rule before looking at the options. Tell yourself what changes from one cell to the next; then check which option follows that rule.
- In matrices, read row by row and column by column. Shape, size, color and count usually change in one direction and stay the same in the other.
- In series, look at the differences. If the gap is not fixed, see whether the gap itself grows, or whether it is a multiplication.
- Read the explanation even when you are right. It puts the rule into words and helps with the next questions of the same kind.
Common mistakes
- Picking the one that “looks” right. Many wrong options match half the rule. Check the whole rule.
- Using the hint too early. The hint costs 1 star off the maximum; save it for when you are stuck between two or three options.
- Showing the answer without thinking. The level counts with 1 star, but you miss the chance to find the rule yourself. You can replay it later.
Levels and scoring
There are 60 levels in 5 tiers of 12: Beginner, Basic, Intermediate, Advanced and Master, from easiest to hardest. Each level unlocks when the previous one is solved. Your score is the total number of stars, from 0 to 180. The questions come from the practice bank, never from the IQ test.
Frequently asked questions
No. They are practice questions with a similar format, and none of them appears in the test.
Yes. Pick it in the level list; your best star score is kept.
No. After two mistakes, “Show answer” appears: the level counts as solved with 1 star and the next one unlocks.
There is no evidence of that. Practice makes you more comfortable with this kind of question; it does not change your IQ.
IQNorth games are a pastime with a challenge. Practice makes you better at this game; it does not raise your IQ or your memory, and nothing here is a consultation with a psychologist. The games are in the member area.
