How to use sudoku grid
What is sudoku grid?
A sudoku grid is a 9 by 9 square divided into nine smaller 3 by 3 boxes, with 81 cells in total. Some cells are pre-filled as clues and the rest are left blank for the solver. The goal is to place the digits 1 to 9 so each row, column and box contains every digit exactly once.
How the sudoku grid is laid out
The 9 by 9 board is split into nine boxes of 3 by 3. The lines between boxes are drawn heavier than the lines inside each box, so you can see the three regions you must satisfy at a glance.
Writing in candidates
Puzzle solvers often write small candidate digits in the corner of each cell, then erase them as they narrow the options. Blank grids give you the room to make your own puzzles or fill in printed clues by hand.
Using blank grids for puzzle books
Print a batch of blank grids to copy puzzles from a screen or book, or to design your own. Keep the grids in a folder and you have a reusable supply for practice and puzzle-making.
