The Hardest Sudoku Puzzle Ever

worlds hardest sudoku

A Finnish mathematician claims that he has created the world’s hardest sudoku puzzle, a brain-teaser which required three months’ work and a billion combinations to produce.

“I called the puzzle AI Escargot, because it looks like a snail. Solving it is like an intellectual culinary pleasure. AI are my initials,” Inkala added. According to a rating system published on the forum of www.sudoku.com, AI Escargot claims the top spot for sudoku’s most baffling puzzles.

Escargot demands those tackling it to consider eight casual relationships simultaneously while the most complicated variants attempted by the general public only require people to think of one or two combinations at any one time, Inkala said.
