Quad Clue Sudoku

The Griddle has another sudoku variation up called Quad Clue Sudoku.  This variation features a six by six sudoku grid with four numbers at some of the grid intersection points.  These four numbers correspond to the four numbers in the four ajoining squares.  It’s another way of providing starting clues, without telling you exactly where they are.  Enjoy!

    Readers of this blog should find Quad Clue Sudoku familiar. It is identical to Quadruple Clue Sudoku which is the name given by famous Ukrainian puzzle maker, Serhiy Grabarchuk, to my nine-by-nine sudoku grid puzzle posted on his Age of Puzzles website in 2006.

    My puzzle was also used in the Second World Sudoku Championship at Prague and the Italian National Sudoku Championship in 2007.

    Hi,

    I had invented a new variant of sudoku : sudokrwazé.
    I’m developping it.
    It is a 18*18 grid.
