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 there you go, here are 31 action packed Sudoku Solving - tips, tricks and techniques in Video Tutorial format. They will help you master solving the easy ones right up to the diabolical ones which "get you" and keep you up all night.
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.
Step by Step Videos
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 youíll 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.

Part 1 - Sudoku Basics Techniques
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)
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.
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.
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.
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.
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.
Time: 6:53 mins
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.
Part 2 - Intermediate Sudoku Techniques
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.
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.
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.
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.
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.
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.
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.
Part 3 - Advanced Sudoku Techniques
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.
Time: 7:16 mins
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.
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.
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.
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 <4> rows and columns. So JellyFish is simply an extension of the Swordfish Technique.
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.
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.
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.
Part 4 - Very Advanced for the Addict
Linked Pairs is quite an advanced solving technique. The method is also sometimes called Remote Pairs. Its name comes from a collection of locked pairs that are linked together remotely. In this episode, we show you how to eliminate candidates using linked pairs in the Sudoku Puzzle.
Grid Coloring Part 1
In Grid Coloring, we use conjugate pairs among cells where one cell of the pair must be true while the other must be false. We use colors to hightlight these true-false states and make interesting deductions that help us in eliminating candidates.
Grid Coloring Part 2
In Grid Coloring part 2, we use a variation in logic to solve complex sudoku puzzles.
Multicolors Part 1
In Multicolors, we use 2 sets of true-false chains instead of one. So we use 4 different colors to use this technique. Thi s is a really interesting technique and very powerful.
Multicolors Part 2
Multicolors part 2 is just a variation of the technique used in part 1. It brings out lots of interesting scenarios.
This technique is borrowed from Dr. Epstein's research at the University of California. In this technique you make a simple path diagram connecting candidates that appear in no other possible places in a group (row, column or box). This path diagram then helps us make some awesome conclusions.
Nishio (Guessing and Backtracking)
If you've tried everything else you can think of, you can try guessing and the backtracking method. Most puzzles which require guessing are obviously not well constructed puzzles. But once in a while we do encounter puzzle where nothing seems to work. here you can try Nishio. We show you how to make guesses and draw rewarding deductions from the guess.
Part 5 - Miscellaneous
In this episode, we cover how Sudoku was created and became popular. We cover the story of how retired Judge Wayne Gould became wealthy via Sudoku Syndication and some more intresting trivia about Sudoku.
In Sudoku variations, we cover interesting variations of Sudoku such as Wordoku, Squiggly sudoku, Sudoku for Kids, 10 x10, 12 x 12, 16 x 16 and Samurai Sudokus. You can enjoy these variations if you get bored of the classic 9 x 9 format.

"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.
