Part 2 – Intermediate Sudoku Techniques |
||
 |
Naked PairsA 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.
|
|
 |
Naked TripletsYou 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.
|
|
 |
Naked QuadrupletThe 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.
|
|
 |
Hidden PairsIn 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.
|
|
 |
Hidden TripletsIf 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 VariationThe 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.
|
||
 |
X Wing – Row VariationIn 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 VariationIn 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 VariationIn 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.
|
||
 |
JellyFishIn 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.
|
||
 |
XY WingThe 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.
|
||
 |
XYZ WingThe 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.
|
||
 |
WXYZ WingThe 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 PairsLinked 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 1In 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 2In Grid Coloring part 2, we use a variation in logic to solve complex sudoku puzzles.
|
|
 |
Multicolors Part 1In 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 2Multicolors part 2 is just a variation of the technique used in part 1. It brings out lots of interesting scenarios.
|
|
 |
Bilocation GraphsThis 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.
