## Sudoku Rules

The object of sudoku is to “solve” the puzzle by filling all the cells with numbers so that no digit repeats in any row, column or box.

That's it. That's really all there is to sudoku. You don't need to use math (no geometry, algebra or calculus is required, thank goodness). You need not use complex logic (until you get to hard and expert puzzles). You just need to remember numbers from 1 to 9.

Some sudoku puzzles are easy and some can be very difficult. The harder the puzzle the more it helps to know techniques and use more complex logic to solve them. That is the fun of sudoku.
