A long-term competition is in effect from March 2026 through 31 December 2030.
The participant who holds the highest verified raw score at the official closing date will be granted complimentary lifetime access to all IQ tests available on this platform, along with a cash prize of €1000.
The leaderboard will remain hidden during the competition and will be published only after its conclusion. Participation implies consent to score disclosure unless one opts out before attempting.
Magnum Opus 100 concludes my years-long work on numerical IQ tests. It features carefully hand-picked items from all my previous sets, alongside a few new additions — each chosen as a shining example of puzzle design.
This test is designed with culture fairness in mind — the only knowledge required to complete it is that of basic arithmetic operations.
To emphasize: no familiarity with concepts such as prime numbers, digits of pi, the golden ratio, or other mathematical trivia is assumed or necessary.
The items generally increase in difficulty as you progress. However, keep in mind that difficulty is subjective to an extent, shaped by each individual's way of thinking and past experiences.
