Rao said, “It is definitely a very tough puzzle, but it can be solved within in hour by any average solver - so long as he makes a few guesses.”Įlaborating on the difference between guesswork and logic, the young genius said, “Guesswork is when you guess a number at a place and proceed to solve the sudoku. Rohan Rao, the 19-year-old puzzle enthusiast and reigning Indian national sudoku champion said, “With guesswork, any good solver can crack a sudoku of any difficulty level within 30 minutes at the most.” He went on to offer to crack this one, and started at 9 pm on Thursday solving it in 21 minutes, saying he could better his timing if he solved it on paper and not on Excelsheet. And if you do crack it, don’t worry, Inkala says he’s already working on the making the next one. Inkala says that logic, patience and care are key. But this time, Inkala feels it would take weeks to solve.įortunately, a background in mathematics is not necessary to crack this one. He had developed a sudoku in 2006, but that one was cracked within 24 hours. Inkala said, “Normal sudoku puzzle logic eliminates the possibilities for each box in two or three steps.īut this one requires puzzlers to think ahead eight or nine steps at a time - making very long deductions to eliminate the possible candidates for each box.” In a sudoku, the objective is to fill in the grid so every column, row and group of nine squares contain the digits one to nine.
