It's As Simple As 123: The Sudoku123 Method

The Sudoku123 method breaks solving down into three simple routines. Randomly search the whole puzzle, and use one of the three routines, apply them consistently, and let the puzzle reveal itself. The video shows you how.

Watch the Method in Action

Start the video and watch how an easy video on Sudoku.club is used to apply the three routines randomly.

Open your own easy sudoku puzzle from your favourite site and copy the solving method demonstrated in the video.

Watch how the three routines are randomly applied to the puzzle.

Three Routines

Master these 3 steps, and you can solve every easy puzzle to completion.

1

Find the Exact Number

Scan a row, column or 3×3 square for the one cell where only a single number can possibly fit. When you spot it, write it straight in – no pencil marks needed.

2

Pencil in Two Numbers

Where a cell could only be one of two possible numbers, lightly pencil both in. This narrows down the options and often sets up the next number you’ll be able to place with confidence.

3

Pencil in Three Numbers

For cells with three possible candidates, pencil in all three. As you keep scanning, the surrounding numbers will gradually rule out the wrong options until only one remains.

Please complete at least 20 easy puzzles before attempting a harder puzzle (required to train your brain).

How to Use These Routines

Use the three routines above to scan an easy puzzle randomly, and follow our video to see exactly how it’s done in real time. Scan the entire puzzle randomly – there’s no fixed starting.

Important: Use 123 routines only, and randomly, and the puzzle will solve itself.
