Alphabet Sudoku (also called Word Sudoku or Letter Sudoku) uses a set of nine letters instead of digits 1–9. The rules are otherwise identical. Many Word Sudoku puzzles are designed so that a specific row, column, or diagonal spells out a word or name once solved. This makes the variant popular in newspapers and as a word-game crossover.

Solving Techniques for Easy Level

Technique Description Level
Same Logic, Different Symbols Every classic Sudoku technique applies — just with letters A–I instead of 1–9. Scanning, naked singles, and box interactions all work identically. Beginner
Letter-to-Number Mapping Internally, A=1, B=2, …, I=9. If numbers are more comfortable, mentally map each letter to its digit while solving. Beginner
