The Hardest Sudoku ever

Sudoku literally meaning “one number” is the most talked about and one of the hardest puzzles. Our daily newspaper catapulted Sudoku to fame and since then every curious guy’s newspaper’s Sudoku has been riddled with numbers. Everyone has his level at Sudoku ranging from the easy to diabolical, but one guy Arto Inkala, a Finnish Mathematician will make even the evilest Sudoku look pitiable. In 2012 Inkala came up with a Sudoku that is claimed to be the hardest of all the Sudoku grids ever made. According to the famous British newspaper The Telegraph, on a Sudoku difficulty scale where the hardest Sudoku grids fare a horrifying 5, Inkala’s puzzle scored a macabre 11.

3. Kashikoky Naru

At number 3 in the list of hardest puzzles to shake your grey matter is the Kashikoky Naru. Now let us dig deep in the abyss of the world of logic. Also called “Kashikoky Naru” which translates to “smartness” in Japanese, Calcudoku is a nightmarish Sudoku where mathematical binary operations jump into those small grids (in case you don’t know how it is played, click here). Thought, Calcudoku is devilish in itself, yet some people can never get much of it, a fortiori, Patrick Min came up with the world’s hardest Calculdokus in his book CalcuDoku, 101 Advanced Puzzles (which even include modulo function (Maths to ad nauseum!)).

Devil

Three gods A, R, and C are called, in some order, True, False, and Random. True always speaks truly, False always speaks falsely, but whether Random speaks truly or falsely is a completely random matter. Your task is to determine the identities of A, R, and C by asking three yes-no questions; each question must be put to exactly one god. The gods understand English but will answer all questions in their own language, in which the words for “yes” and “no” are “dam and “ja,” in some order. You do not know which word means which.
