Mensa's core members and top Sudoku experts
A sophisticated Sudoku

The Sudoku puzzles in "Mensa Sudoku Premier 500" are of the highest quality in the world, as they were created by key members of British Mensa.
The 500 Sudoku puzzles are carefully selected from among the most difficult puzzles, and they confirm the Sudoku proposition that “all Sudoku puzzles can be solved logically.”
The intricately structured puzzles will challenge the logical thinking of Sudoku enthusiasts.

Sudoku can also be created on a computer using patterns.
However, Sudoku, which is created by computer programming, is less fun because it can be solved in illogical ways.
However, the author of this book, puzzle expert Peter Gordon, created each problem himself and included high-level problems, including those that cannot be solved even by Sudoku solution websites or programs.
The answer must be found only with accurate evidence and sophisticated reasoning.


For Sudoku enthusiasts of intermediate or higher level
Includes 500 of the highest level Sudoku puzzles

If you compare the problems at the first level, STANDARD level, to those in other Sudoku books, you will find them much more difficult.
In particular, the MEGA PREMIUM level problems are top-level problems that even Sudoku experts have difficulty solving. If you can solve the last 500 problems without any problems, you will have skills that are comparable to those of the members of Mensa, the world's best brain group.

In Sudoku, you should only fill in numbers when there is an exact basis for it.
This is because if you enter the wrong number once, you will be stuck in another square and have to start over from the beginning.
Those who have been solving problems by filling in numbers with luck or guesswork might shake their heads in front of this book.
But for those who enjoy the intellectual thrill of finding logical clues in the numbers written in the squares and filling in the last square, Mensa Sudoku Premier 500 will be the best book.
