Here is your Sudoku
What it is and how it works
Sudoku (Japanese:
sudoku), sometimes spelled Su Doku, is a logic-based placement puzzle, also
known as Number Place in the United States. The goal is to fill in the empty
cells, one number in each, so that each column, row, and region contains the
numbers 1–9 exactly once. Each number in the solution therefore occurs
only once in each of three "directions", hence the "single numbers"
implied by the puzzle's name.
Here we use a form and you only have to fill out the little white squares, enter
your name and CLAW-ID and hit send. That is all!
