Sudoku Solving Techniques: Naked Pairs and Hidden Pairs

After Naked Singles and Hidden Singles, the next scan that makes progress without guessing is a pair.

Sudoku Solving Techniques: X-Wing

X-Wing is a later advanced scan, after singles, pairs, triples, quads, pointing pairs, and box-line reduction. An X-Wing is one leftover digit that has only two homes in each of two rows, and those homes sit in the same two columns — a rectangle.

6x6 Wordoku puzzle with letters of STUDIO, beside its solution with the hidden word on the shaded row

How Wordoku Works

How to play Wordoku: it is letter Sudoku with a hidden word. The symbols are the distinct letters of one word. Fill every empty cell so each row, each column, and each box holds those letters exactly once. One row or column starts completely blank — on a board like this one, when you finish it, it spells the word. This guide uses a 6×6 board whose hidden line is STUDIO.
