This page is for Classic Sudoku solving techniques. For Variants, see Variant Solving Techniques. The techniques listed here will usually apply when variant constraints are present, but the ways the variants interact with these techniques will change depending on the specific constraint.
Logical Solving Techniques
(Really, all the techniques on this page are "logical" from a certain point of view.)
- Subsets (Hidden and Naked)
- Locked Candidates
- Single Digit Techniques
- Alternating Inference Chains
- Almost Locked Sets
- XYZ-Wing, WXYZ-Wing (aka Bent Quad)
- Sue de Coq
- ERI Pair
- ALS-XZ (including doubly-linked)
- ALS-XY-Wing (including triply-linked)
- ALS-W-Wing
- Multiple and Dynamic Forcing Chains
- Global Techniques ("Exotic")
Uniqueness Techniques
- Unique Rectangle
- Unique Loop
- Extended Rectangle
- Bivalue Universal Grave
- Gurth's Symmetrical Placement
- Distinction Theory
