Step-by-step guide to solve and create beginner Sudoku puzzles
Step 1
Use your ruler to draw a 4 by 4 grid with darker lines every two squares so you have four 2x2 boxes.
Step 2
Write the Sudoku rules at the top: fill each row each column and each 2x2 box with the numbers 1 to 4 with no repeats.
Step 3
In the top row write the numbers 1 2 3 4 in order using your pencil.
Step 4
In the second row write 3 4 1 2 by moving the first two numbers of the top row to the end.
Step 5
In the third row write 2 1 4 3 by swapping the pairs from the top row.
Step 6
In the fourth row write 4 3 2 1 by swapping the pairs from the second row so the grid is now a complete solution.
Step 7
Erase six numbers from different spots on the completed grid to make a beginner puzzle with plenty of clues left.
Step 8
In each empty cell write small pencil candidate numbers (1 to 4) for which numbers could go there based on the row column and box.
Step 9
Cross out any candidate that appears in the same row column or box so only the allowed candidates remain.
Step 10
When a cell has only one candidate erase the tiny numbers and write the final number in the cell.
Step 11
Repeat checking candidates and filling single-candidate cells until the whole puzzle is solved.
Step 12
Make a fresh puzzle by relabelling every number in the solved grid (for example swap all 1s with 2s) and then erase a few squares to create a new beginner puzzle.
Step 13
Colour and decorate your puzzle page to make it look awesome.
Step 14
Take a photo or write a short note about your Sudoku and share your finished creation on DIY.org

What can I use instead of a ruler, pencil, or camera if I don't have them?
Use a straight-edged book or a cereal-box edge instead of a ruler, a mechanical or soft-lead pencil in place of a wooden pencil so you can erase, and your phone or tablet camera to take the photo for DIY.org.
My candidates and crossings look messy or I erased part of a number—how can I fix mistakes and keep the puzzle tidy?
Redraw a clean 4 by 4 grid with darker lines every two squares using a ruler or book edge, write tiny candidate numbers lightly in the corners so you can erase smudges, and erase carefully before writing final numbers when a cell has only one candidate.
How can I change this activity for younger children or older kids who want more challenge?
For younger kids erase only three numbers and use big bold digits or number stickers to make filling easier, while older kids can erase more squares, add a timer, or relabel every number to create harder new puzzles as in the relabelling step.
Any ideas to make my Sudoku puzzle more creative or to reuse it later?
Colour-code each number with different coloured pencils when you colour and decorate the page, relabel all numbers to make a fresh puzzle as instructed to reuse the solved grid, and then take a photo or write a short note to share on DIY.org.
