Puzzles are special puzzles that require clarity of mind and ingenuity to solve. Among these tasks there are both very simple specimens that can succumb even to the inquisitive mind of a child, and incredibly complex riddles accessible only to professionals.
Instructions
Step 1
Today, it is customary to single out several puzzles, the intellectual complexity of which raises them to the level of world-wide riddles. So, professional Sudoku lovers can get acquainted with a special problem developed by a Finnish mathematician back in 2012. According to research, this unique puzzle is ranked 11th on the "unsolved" scale, while the rest of the "aerobatics" sudoku only claim 5th place of honor.
Step 2
Serious competition for Sudoku can be made by its special varieties of sum-do-ku and tracing-dock, which you can try to solve by going to the pages of a specialized resource, which, based on statistics, recognized these tasks as one of the most rarely guessed riddles.
Step 3
The most difficult logical task today is considered to be the problem of the three gods, who should be asked only a few questions to determine their belonging. This task belongs to the pen of the philosopher George Boulos, who published his creation in 1992 in one of the Italian newspapers.
Step 4
Our compatriots also had a hand in creating the most difficult puzzles. So, the Russian cybernetic scientist Mikhail Bongard developed a task of the same name, associated with comparing the right and left halves of the image in order to find the differences and the law to which these visual images are subject.
Step 5
But the most interesting work of the American mathematician Martin Gardner, the author of many sensational puzzles, today is considered to be the allocation of "fortitude numbers". At first glance, the task is surprisingly simple. Of the many-digit numbers available in nature, it is necessary to select one that could be reduced to a single-digit one by sequentially multiplying the numbers that make up its composition, for example, 88-64-24-8. In the above example, it took four steps, so 88 has a toughness of 4 levels. Now you need to try to find a value with less persistence.
Step 6
A mixture of crossword and sudoku is a puzzle called kakura. The goal of the task is to fill in the cells with non-repeating numbers of a series from one to nine, but this must be done so that the sum of the numbers you specify corresponds to the values specified in the individual cells.
Step 7
Do you love the Japanese game of go, the goal of which, like in a children's war, is to capture the enemy's square? Then try to solve the most difficult problem in the world of this class, which, according to researchers, even the most experienced players have already spent more than a thousand hours of vigorous mental activity.
