Easy Sudoku Puzzle

See also the small variant based on sums - click here or on MiniSum above.

  In standard SUDOKU puzzles (as on the left), the aim is to place the digits from 1 to 9 in each small square so each row, column and 3x3 mini-array (surrounded by bold lines) contains each digit just once.

  With Sudoku-X puzzles, it is also required that each main diagonal contains each digit just once.  A 'correct' Sudoku-X will not be soluble unless use is made of the additional diagonal requirements (i.e. you will not be able to fill it in fully if you treat it like a standard Sudoku).

  The Books page lists collections of both types of puzzles.      The Downloads page offers a free Windows-compatible Player program for Sudoku/-X puzzles, as well as downloads of the puzzles featured here.

  I also set Killer Sudoku puzzles (which, despite the name, are not necessarily difficult!). These involve Sudoku grids in which no squares are pre-filled in but in which meshes are used to surround given areas, the sum of all contained square values being indicated.
