Sudoku Puzzles by Dr Gareth Moore

Sudoku A standard 9x9 Sudoku puzzle consists of a square grid, with bold lines every third square in order to sub-divide it into nine 3 by 3 boxes. The aim is simple: place the digits 1 to 9 into the puzzle grid so that each digit occurs once in every row, column and bold-lined 3 by 3 box. Some digits are already given - these constrain the puzzle in such a way that there is only one possible solution, which in a proper Sudoku can always be reached via reasonable logical deduction. Guessing is never required.
