Featured Puzzle: Chain Sudoku #1
I learned about Chain Sudoku puzzles fairly recently, and thought they’d make for a visually cool presentation. This form was popularized under the trademarked name Strimko, which was invented in 2008 by the Grabarchuk family. They’re similar to Jigsaw Sudoku puzzles, with jumbled regions, except they are not necessarily orthogonally contiguous.
Fill in the grid cells with the digits 1-9 such that no number repeats in any row or column, or along any like-colored chain of cells.
In the future, I’ll add new tutorials for specific Sudoku variations. In the meantime, you can find basic Sudoku techniques in our Solving Guide.
