Cogni33 is a high range pattern recognition test consisting of 33 numerical items that should be solved in the most logical and simplest way. There is no time limit, and answers should be carefully thought out. Discussion with others about solutions is not allowed. The items are not arranged in order of difficulty. To receive your score report, please send your solutions to dawid.skrzos@o2.pl along with proof of identity. Three attempts are allowed, however, only the first two attempts are considered official scores. The test is free of charge.
An award of €1,000 will be granted to the first person who solves at least 30 out of 33 items.
To be eligible for the prize, you must consent to having your name and surname published on the website. This is to confirm the authenticity of the award.
Individuals who have been definitively identified as fraudsters are prohibited from taking the test. This measure is implemented to mitigate the risk of ongoing fraudulent activities, such as the sale of answers online.
