Supreme Sudoku 15x15 Puzzle Book

15 x 15 sudoku puzzles work just the same as regular 9 x 9 sudoku puzzles, but on a larger scale! Infact whereas a normal sudoku has 81 squares in it, a 15x15 sudoku has 225 squares in it.

Here are the rules of 15 x 15 sudoku:

- Place each number from 1 - 15 exactly once in each row, column and 5 x 3 bold-lined box that compose the grid.

That's all there is to it!

15 x 15 Sudoku Questions

With our 15x15 sudoku puzzles, you will just need the standard sudoku solving logic: looking at possible values for a square and also where each number can be placed within a region. Thus if there is only one square that can contain the 15 within a region, then you know it must be placed there.

Each puzzle can be solved through the above two rules, so you won't need to do anything like look at sets which gets pretty tricky when there are 15 numbers to take into account in each and every region of the 45 regions in the puzzle grid.
