Dear Friends,

I have a confession to make. I am hopelessly addicted to Sudoku above and beyond reason. I have been creating and solving Sudoku’s for several years and have been helping Sudoku enthusiasts like you in Solving Sudoku Puzzles. I receive so many emails that I thought – why not create video tutorials which users can follow along and feed their Sudoku frenzy.

So regardless of whether you’re a rank newbie or a Sudoku buff, these tutorials are for you. These In-Depth Sudoku Video Tutorials will show you everything you will ever need to know about Solving Any Sudoku Puzzle.

Books and Manuals are hard to follow along. Why go through pages of laborious explanations when you can see and understand solving techniques visually in the form of a video. Our video tutorials explain everything step by step in a simple and easy to understand format. It’s like sitting next to a trainer.

We start with the basics and cover some of the most advanced techniques that you値l not find elsewhere. There are a lot of Internet sites out there on Sudoku techniques, but none of them are as comprehensive as this package. Second they mostly contain text explanations with very few pictures which make them hard to understand and lack the amazingly powerful approaches on Sudoku Solving Strategies like we cover. Third, most of the Sudoku techniques are written by programmers for programmers, which make them hard to follow along.

Sudoku Sudoku Basics

Sudoku Basics

Sudoku is a numbers game. To solve these puzzles, all you need is simple Logic and there’s no mathematics involved. In this episode, we cover the basics of Sudoku (rows, columns, boxes, big rows, big columns, candidates, buddies and givens)


Sudoku Rules of Sudoku

Rules of Sudoku

In this Video tutorial, we explore the rules of Sudoku. There are essentially 3 rules of Sudoku. We show you examples of moves that violate the rules of Sudoku and show you valid moves that comply with the rules of Sudoku.


Sudoku Concepts and Terminology

Concepts and Terminology

In this Video tutorial, we discuss 4 important concepts in Sudoku Solving techniques. We discuss the concept of unique solutions. We also explore minimal sudoku puzzles (sudokus with the least number of givens) and the concept of symmetry. We also introduce you to the concept of buddies.


Sudoku Single Choice (Naked Singles)

Single Choice (Naked Singles)

In this tutorial, we start with the first technique in solving sudokus. It’s called Single Choice or Naked Singles. Any cells which have only one candidate can safely be assigned that value. It is very important whenever a value is assigned to a cell, that this value is also excluded as a candidate from all other blank cells sharing the same row, column and box. We walk through some easy puzzles and demonstrate Naked Singles.


Sudoku Candidates


In this tutorial, we show you how to add candidates or pencil marks in the empty cells while solving sudokus. It’s impossible to get very far without carefully maintaining a list of ‘possible values’ or candidates for each blank cell. Candidates are very essential to understanding some of the advanced techniques, so we cover the concept of candidates in great detail with real examples.


Sudoku Scanning


Scanning is probably the most useful technique in solving the majority of Sudoku’s. Using real sudoku examples, we show you how to narrow down your candidates using Scanning and actually solve cells.


Sudoku Elimination


Elimination can be used quote often in easy and medium Sudoku puzzles. All you have to do is find a candidate that appears only once within a row, a column or a box, then you can safely use that candidate to solve the cell. In this tutorial, we show you step by step how to find these hidden singles.


Sudoku Naked Pairs

Naked Pairs

A Naked Pair is an isolated pair of candidates that appear exactly in two cells within a row, a col, or a box. Need more information? Watch this tutorial where we show you exactly how to use Naked Pairs in a variety of situations.


Sudoku Naked Triplets

Naked Triplets

You can easily extend the logic of naked pairs to three cells and this technique is called Naked Triplets. A Naked Triple occurs when three cells in a group contain no candidates other that the same three candidates. The cells which make up a Naked Triple don’t have to contain every candidate of the triple. If these candidates are found in other cells in the group they can be excluded.


Sudoku Naked Quadruplet

Naked Quadruplet

The same principle that applies to Naked Pairs can also be applied to four cells – Naked Quadruplets. These are hard to spot, but we show you some tips and tricks to identify this arrangement.


Sudoku Hidden Pairs

Hidden Pairs

In Hidden Pairs, you are still looking for 2 identical candidates in exactly 2 cells within a group, just like we did in Naked Pairs. But this time, the pairs are “hidden” amongst other candidates. If two cells in a group contain a pair of candidates (hidden amongst other candidates) that are not found in any other cells in that group, then other candidates in those two cells can be excluded safely.


Sudoku Hidden Triplets

Hidden Triplets

If three candidates are restricted to three cells in a given group, then all other candidates in those three cells can be excluded. In this video tutorial, we show you how Hidden Triplets work. We also show you how to find the “hidden” interlopers in Triplets that make them difficult to spot.


Sudoku Interaction Part 1 (Locked Candidates)

Interaction Part 1 (Locked Candidates)

Sometimes a candidate within a box is restricted to one row or column. Since one of these cells must contain that specific candidate, the candidate can safely be excluded from the remaining cells in that row or column outside of the box. In this video tutorial, we explore this interaction between a row and a box.


Sudoku Interaction Part 2 (Locked Candidates)

Interaction Part 2 (Locked Candidates)

Sometimes a candidate within a row or column is restricted to one box. Since one of these cells must contain that specific candidate, the candidate can safely be excluded from the remaining cells in the box. In this video tutorial, we explore this interaction between a column and a box.


Sudoku X Wing - Column Variation

X Wing – Column Variation

The X Wing family of techniques are no more difficult than the simpler techniques, but require observation as to how specific candidates relate to each other (in particular patterns) beyond any given row, column or box. In this video tutorial, we deconstruct the X-Wing technique and show you how to use it to eliminate candidates.


Sudoku X Wing - Row Variation

X Wing – Row Variation

In this video tutorial, we’ll cover the row variation of the X-wing technique. This time, we’ll use columns to identify our X-Wing and eliminate candidates from the rows.


Sudoku SwordFish - Column Variation

SwordFish – Column Variation

In this video tutorial, we explore the Swordfish technique. The Swordfish technique is very similar to the X-wing technique. The only difference is that in X-Wing you’re looking for rows and columns Whereas in Swordfish, you’re looking for rows and columns.


Sudoku SwordFish - Row Variation

SwordFish – Row Variation

In this episode, we’ll cover the row variation of the Swordfish technique. We call it the Row variation, because this time, we’ll be removing candidates from the instead of Columns. So the name of the variation comes from we remove the candidates from.


Sudoku JellyFish


In X-wing we looked at 2 rows and columns And in Swordfish we looked at three rows and columns. Now in JellyFish, we’ll be looking at rows and columns. So JellyFish is simply an extension of the Swordfish Technique.


Sudoku XY Wing

XY Wing

The XY wing is quite an advanced technique and just like in many of the previous techniques, it helps us in eliminating candidates from certain cells. So let’s see this technique in action in this video tutorial.


Sudoku XYZ Wing

XYZ Wing

The XYZ wing is simply an extension of the XY wing, but with a slightly different arrangement. In this video tutorial, we demonstrate several variations of the XYZ arrangement.


Sudoku WXYZ Wing


The WXYZ-Wing tecnique is simply an extension of the XYZ-Wing. The objective of using this technique is to eliminate a certain candidate Z instead of finding out a solution to a cell. Similar to XYZ-Wing, one of the cells has the candidates WXYZ.

“I don’t think I could explain any better how to solve Sudoku …”

Recently I came across a Sudoku video tutorial I just had to share with you. I don’t think I could explain any better how to solve Sudoku. The author of this video, Neel Mehta, in 31 lessons, shows you in great detail the Sudoku techniques needed to reach a solution. I have covered most of the techniques on this website, but Neel goes into more detail than I do.
