Mathematicians have uncovered a powerful pattern known as the 'Phistomefel Ring' This pattern means that the 16 squares around the central 3x3 ring will always contain the same digits as the 2x2 squares in the corners.

Since this will always be the case in any legitimate Sudoku , you can use this rule to solve otherwise impossible problems.

Professor Sarah Hart says knowing about these rules can be 'another tool in the armoury' for anyone struggling to solve puzzles.

'These equivalent sets can be very useful for hard Sudokus where all the usual methods aren't getting anywhere,' she added. 'Kind of like in chess, the more openings, defences or other stratagems you know, the more options you have to get out of trouble. '.
