Circular Sudoku
Sudoku puzzles have become a popular pastime of late and here in the
Department of Mathematical Sciences Prof.
Peter Higgins has developed a new variant of them which we call circular, or
target, sudoku. Prof. Higgins' puzzles began appearing in the Sunday Telegraph
in June 2005, but just in case you have missed them we have
one here for you to have a go at. The instructions are given with the puzzle.
