Samurai sudoku puzzles follow the rules of traditional sudoku. All you need to do is get your head wrapped around them the right way.
Think of them as five overlapping 9x9 grids. Every row, column, and 3x3 cage of these individual grids must contain one and only one example of the digits from 1 to 9. That's just like a regular sudoku.
Of course what makes it tricky, but also what is a source of clues, is that the four overlapping cages must serve two puzzles at a time. There is, of course, only one solution. So don't guess, deduce!
If you are already a fan of these puzzles, have a look at our new Samurai Sudoku book available on Amazon and also for immediate download from our PDF store. It contains 75 sudoku rated from easy to hard. We hope you enjoy it!
