Hi,

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

You can find more free games and puzzles such as Le Rondodu.

Enjoy!
And thank you for any visit.

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.
