数独 SUDOKU From Japanese 数 suu or sü (« digit »), and 独 doku (« single »)
數獨 Chinese
Sudoku-As is a site in development. Instead of conventional amorphous, deformed or zebra sudokus (that I hate a little), I am there to finalize some collections of geometrical sudokus (in perfect circle, pentagon, etc.) and of thematic sudokus (in form of firtree for Christmas, heart-shaped for the St Valentine's Day, etc.). At the moment these special puzzles are available only on explicit inquiry.
From the "clues" or the "givens" numerals, complete the grid by filling in all the empty cells so that every row, each column and the nine 3x3 box contains every basic digit from 1 to 9 inclusive, but just once and only once for each numeral.
To allow you to calculate exactly your game's time, I supply here a friendly and flexible stopwatch.
