Samurai Sudoku can have an enormous number of variations, such as the examples on this and other pages (see below and to the right).
Samurai Sudoku takes Sudoku and transforms it into a larger puzzle without making it ridiculously complex. As opposed to increasing the number of possible digits in a puzzle, in Samurai Sudoku multiple grids are overlaid. They must be solved simultaneously in order to complete the puzzle.
Simply place the digits 1 to 9 into every row, column and bold-lined 3x3 box of each of the underlying regular 9x9 Sudoku grids - or for other sizes of underlying grid place 1-6 or whatever the grid size is, and fill the 2x3 or other box sizes in a similar way.
There is only ever one solution, and guessing is never required.
We can supply Samurai Sudoku Variety puzzles for any sizes of grid and in any arrangement imaginable, and even with a wide range of further variations, such as Sudoku-X regions or Jigsaw pieces.
All of our puzzles are either entirely hand-made or have significant manual input into the process.
